You can't - enum values have to be integral values. You can either use attributes to associate a string value with each enum value, or in this case if every separator is a single character you could just use the <code>char</code> value:

<pre><code>enum Separator
{
 Comma = ',',
 Tab = '\t',
 Space = ' '
}
</code></pre>

(EDIT: Just to clarify, you can't make <code>char</code> the underlying type of the enum, but you can use <code>char</code> constants to assign the integral value corresponding to each enum value. The underlying type of the above enum is <code>int</code>.)

Then an extension method if you need one:

<pre><code>public string ToSeparatorString(this Separator separator)
{
 // TODO: validation
 return ((char) separator).ToString();
}
</code></pre>

blocks|key|699443|text|据我所知，您不允许将字符串值分配给枚举。你能做的就是创建一个包含字符串常量的类。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|699444|public+static+class+SeparatorChars

 [EnumMember(Value = &quot;KM&quot;)]
 Kilometer,
 [EnumMember(Value = &quot;MI&quot;)]
 Miles
}

This way the result value for UnitOfMeasure will be KM or MI. This also can be seen in Andrew Whitaker <a href="https://stackoverflow.com/questions/26391632/how-to-serialize-enums-to-different-property-name-using-json-net#answer-26391780">answer</a>.

For people arriving here looking for an answer to a more generic question, you can extend the static class concept if you want your code to look like an <code>enum</code>.

The following approach works when you haven't finalised the <code>enum names</code> you want and the <code>enum values</code> are the <code>string</code> representation of the <code>enam name</code>; use <code>nameof()</code> to make your refactoring simpler.

<pre><code>public static class Colours
{
 public static string Red =&gt; nameof(Red);
 public static string Green =&gt; nameof(Green);
 public static string Blue =&gt; nameof(Blue);
}
</code></pre>

This achieves the intention of an enum that has string values (such as the following pseudocode):

<pre><code>public enum Colours
{
 "Red",
 "Green",
 "Blue"
}
</code></pre>

blocks|key|699586|text|首先，您尝试分配字符串而不是字符，即使它们只是一个字符。使用'，‘代替’，‘。下一件事是，枚举只接受没有char的整数类型，您可以使用Unicode值，但我强烈建议您不要这样做。如果你确定这些值在不同的文化和语言中保持不变，我会使用带有常量字符串的静态类。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|699587|entityMap^0|1G|4|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|K|8|@]|D|@]|E|$]]]|G|$]]

Well first you try to assign strings not chars, even if they are just one character. use ',' instead of ",". Next thing is, enums only take integral types without <code>char</code> you could use the unicode value, but i would strongly advice you not to do so.
If you are certain that these values stay the same, in differnt cultures and languages, i would use a static class with const strings.

While it is really not possible to use a <code>char</code> or a <code>string</code> as the base for an enum, i think this is not what you really like to do.

Like you mentioned you'd like to have an enum of possibilities and show a string representation of this within a combo box. If the user selects one of these string representations you'd like to get out the corresponding enum. And this is possible:

First we have to link some string to an enum value. This can be done by using the <code>DescriptionAttribute</code> like it is described <a href="https://stackoverflow.com/questions/8828511/in-an-enum">here</a> or <a href="https://stackoverflow.com/questions/479410/enum-tostring">here</a>.

Now you need to create a list of enum values and corresponding descriptions. This can be done by using the following method:

<pre><code>/// &lt;summary&gt;
/// Creates an List with all keys and values of a given Enum class
/// &lt;/summary&gt;
/// &lt;typeparam name="T"&gt;Must be derived from class Enum!&lt;/typeparam&gt;
/// &lt;returns&gt;A list of KeyValuePair&amp;lt;Enum, string&amp;gt; with all available
/// names and values of the given Enum.&lt;/returns&gt;
public static IList&lt;KeyValuePair&lt;T, string&gt;&gt; ToList&lt;T&gt;() where T : struct
{
 var type = typeof(T);

 if (!type.IsEnum)
 {
 throw new ArgumentException("T must be an enum");
 }

 return (IList&lt;KeyValuePair&lt;T, string&gt;&gt;)
 Enum.GetValues(type)
 .OfType&lt;T&gt;()
 .Select(e =&gt;
 {
 var asEnum = (Enum)Convert.ChangeType(e, typeof(Enum));
 return new KeyValuePair&lt;T, string&gt;(e, asEnum.Description());
 })
 .ToArray();
}
</code></pre>

Now you'll have a list of key value pairs of all enums and their description. So let's simply assign this as a data source for a combo box.

<pre><code>var comboBox = new ComboBox();
comboBox.ValueMember = "Key"
comboBox.DisplayMember = "Value";
comboBox.DataSource = EnumUtilities.ToList&lt;Separator&gt;();

comboBox.SelectedIndexChanged += (sender, e) =&gt;
{
 var selectedEnum = (Separator)comboBox.SelectedValue;
 MessageBox.Show(selectedEnum.ToString());
}
</code></pre>

The user sees all the string representations of the enum and within your code you'll get the desired enum value.

blocks|key|700186|text|添加更多的东西，因为这里的一些答案没有使用枚举的要点。当然，一种选择是将定义良好的字符串作为静态变量等，但随后您也会为非法值打开接口，即您需要验证输入。对于枚举，可以保证只将允许的值传递到接口。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|700187|enum+Separator

Adding still something more as some of the answers here are missing the point of using enums. Naturally one option is is to have well defined strings as static variables etc, but then you're opening your interface for illegal values also, i.e. you need to validate the input. With enums it's guaranteed that only allowed values are passed to your interface.
<pre><code>enum Separator
{
 Comma,
 Tab,
 Space,
 CRLF,
 SoFunny
}
</code></pre>
In addition to this you can use e.g. an internal Dictionary for the mapping purposes.
<pre><code> private readonly Dictionary&lt;Separator, string&gt; separatorMap = new Dictionary&lt;Separator, string&gt;()
 {
 { Separator.Comma, &quot;,&quot; },
 { Separator.Tab, &quot;\t&quot; },
 { Separator.Space, &quot; &quot; },
 { Separator.CRLF, &quot;\r\n&quot; },
 { Separator.SoFunny, &quot;Your Mom&quot; }
 };
</code></pre>
Even more sophisticated method for doing this is to create a <a href="https://docs.microsoft.com/en-us/dotnet/csharp/programming-guide/classes-and-structs/how-to-create-a-new-method-for-an-enumeration" rel="nofollow noreferrer">static class</a> to give the enum new capabilities and handle the mapping there.
Example of using code above would be like.
<pre><code>public string TransformToSingleString(List&lt;string&gt; values, Separator separator)
{
 var separateWith = separatorMap[separator];
 ...
}
</code></pre>

blocks|key|484291|text|我希望有一个更优雅的解决方案，比如只允许在语言级别使用字符串类型enum，但似乎还不支持它。下面的代码基本上与其他答案的想法相同，但我认为它更短，可以重复使用。您所要做的就是在每个enum条目上添加一个[Description("")]，并添加一个包含10行的类。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|484292|类：|484293|public+static+class+Extensions

I wish there were a more elegant solution, like just allowing string type <code>enum</code> in the language level, but it seems that it is not supported yet. The code below is basically the same idea as other answers, but I think it is shorter and it can be reused. All you have to do is adding a <code>[Description(&quot;&quot;)]</code> above each <code>enum</code> entry and add a class that has 10 lines.
The class:
<pre><code>public static class Extensions
{
 public static string ToStringValue(this Enum en)
 {
 var type = en.GetType();
 var memInfo = type.GetMember(en.ToString());
 var attributes = memInfo[0].GetCustomAttributes(typeof(DescriptionAttribute), false);
 var stringValue = ((DescriptionAttribute)attributes[0]).Description;
 return stringValue;
 }
}
</code></pre>
Usage:
<pre><code> enum Country
 {
 [Description(&quot;Deutschland&quot;)]
 Germany,
 [Description(&quot;Nippon&quot;)]
 Japan,
 [Description(&quot;Italia&quot;)]
 Italy,
 }

 static void Main(string[] args)
 {
 Show(new[] {Country.Germany, Country.Japan, Country.Italy});

 void Show(Country[] countries)
 {
 foreach (var country in countries)
 {
 Debug.WriteLine(country.ToStringValue());
 }
 }
 }
</code></pre>

We can't define enumeration as string type. The approved types for an enum are byte, sbyte, short, ushort, int, uint, long, or ulong.

I am trying to define an <code>Enum</code> and add valid common separators which used in CSV or similar files. Then I am going to bind it to a <code>ComboBox</code> as a data source so whenever I add or remove from the Enum definition, I would not need to change anything in the combo box.

The problem is how can I define enum with string representation, something like:

<code>public enum SeparatorChars{Comma = ",", Tab = "\t", Space = " "}</code>

How to define an enum with string value?

我正在尝试定义一个Enum并添加在CSV或类似文件中使用的有效公共分隔符。然后，我将把它绑定到一个ComboBox作为数据源，这样每当我在枚举定义中添加或删除时，我就不需要更改组合框中的任何内容。问题是我如何使用字符串表示来定义枚举，比如：public enum SeparatorChars{Comma = ",", Tab = "\t", Space = " "}
