Fill the combobox manually and do a string replace on the enum.

Here is exactly what you need to do:

<pre><code>comboBox1.Items.Clear();
MyEnum[] e = (MyEnum[])(Enum.GetValues(typeof(MyEnum)));
for (int i = 0; i &lt; e.Length; i++)
{
 comboBox1.Items.Add(e[i].ToString().Replace("_", " "));
}
</code></pre>

To set the selected item of the combobox do the following:

<pre><code>comboBox1.SelectedItem = MyEnum.My_Value_2.ToString().Replace("_", " ");
</code></pre>

blocks|key|4322|text|如果您有权访问Framework3.5，则可以执行以下操作：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4323|Enum.GetValues(typeof(MyEnum))

++++++++++++++++{
++++++++++++++++++++Value+=+e,

++++++++++++++++});|code-block|syntax|javascript|4324|这将返回一个匿名类型的文本，其中包含一个IEnumerable属性和一个Text属性，前者是枚举类型本身，后者包含枚举数的字符串表示形式，但下划线被替换为空格。|4325|Value属性的用途是，您可以确切地知道在组合框中选择了哪个枚举数，而不必取回下划线并分析字符串。|4326|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|N|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|O|8|@]|9|@]|A|$]]|$1|I|3|J|5|6|7|P|8|@]|9|@]|A|$]]|$1|K|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|L|$]]

If you have access to the Framework 3.5, you could do something like this:

<pre><code>Enum.GetValues(typeof(MyEnum))
 .Cast&lt;MyEnum&gt;()
 .Select(e=&gt; new
 {
 Value = e,
 Text = e.ToString().Replace("_", " ")
 });
</code></pre>

This will return you an IEnumerable of an anonymous type, that contains a Value property, that is the enumeration type itself, and a Text property, that will contain the string representation of the enumerator with the underscores replaced with space.

The purpose of the Value property is that you can know exactly which enumerator was chosen in the combo, without having to get the underscores back and parse the string.

blocks|key|1914640|text|如果你使用的是.NET+3.5，你可以添加这个扩展类：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1914641|public+static+class+EnumExtensions+{

++++private+static+string+ToFriendlyName(this+string+orig)+{
++++++++return+orig.Replace("_",+"+");

}|code-block|syntax|javascript|1914642|然后，要设置您的组合框，您只需执行以下操作：|1914643|MyEnum+val+=+MyEnum.My_Value_1;
comboBox1.DataSource+=+val.GetFriendlyNames();
comboBox1.SelectedItem+=+val.GetFriendlyName();|1914644|这应该适用于任何枚举。您必须确保对包含EnumExtensions类的名称空间使用using语句。|1914645|entityMap^0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Q|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|R|8|@]|9|@]|A|$E|F]]|$1|K|3|L|5|6|7|S|8|@]|9|@]|A|$]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

If you're using .NET 3.5, you could add this extension class:

<pre><code>public static class EnumExtensions {

 public static List&lt;string&gt; GetFriendlyNames(this Enum enm) {
 List&lt;string&gt; result = new List&lt;string&gt;();
 result.AddRange(Enum.GetNames(enm.GetType()).Select(s =&gt; s.ToFriendlyName()));
 return result;
 }

 public static string GetFriendlyName(this Enum enm) {
 return Enum.GetName(enm.GetType(), enm).ToFriendlyName();
 }

 private static string ToFriendlyName(this string orig) {
 return orig.Replace("_", " ");
 }
}
</code></pre>

And then to set up your combo box you'd just do:

<pre><code>MyEnum val = MyEnum.My_Value_1;
comboBox1.DataSource = val.GetFriendlyNames();
comboBox1.SelectedItem = val.GetFriendlyName();
</code></pre>

This should work with any Enum. You'd have to make sure you have a using statement for the namespace that includes the EnumExtensions class.

blocks|key|1914649|text|如果您能够修改定义枚举的代码，以便可以在不修改实际枚举值的情况下向值添加属性，则可以使用此扩展方法。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1914650|///+<summary>

If you are able to modify the code defining the enum, so you could add attributes to the values without modifying the actual enum values, then you could use this extension method.

<pre><code>/// &lt;summary&gt;
/// Retrieve the description of the enum, e.g.
/// [Description("Bright Pink")]
/// BrightPink = 2,
/// &lt;/summary&gt;
/// &lt;param name="value"&gt;&lt;/param&gt;
/// &lt;returns&gt;The friendly description of the enum.&lt;/returns&gt;
public static string GetDescription(this Enum value)
{
 Type type = value.GetType();

 MemberInfo[] memInfo = type.GetMember(value.ToString());

 if (memInfo != null &amp;&amp; memInfo.Length &gt; 0)
 {
 object[] attrs = memInfo[0].GetCustomAttributes(typeof(DescriptionAttribute), false);

 if (attrs != null &amp;&amp; attrs.Length &gt; 0)
 {
 return ((DescriptionAttribute)attrs[0]).Description;
 }
 }

 return value.ToString();
}
</code></pre>

blocks|key|1909266|text|我认为将内部枚举名称映射到用户空间并不是一个好主意。如果重构枚举值呢？所以我建议你看看这个article+(Localizing+.NET+Enums)。使用本文描述的技术，您不仅可以用空格替换'_‘，还可以为不同的语言(使用资源)创建不同的枚举表示。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1909267|entityMap|0|LINK|mutability|MUTABLE|url|http://www.codeproject.com/KB/cs/LocalizingEnums.aspx^0|19|V|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

I think that this is not very good idea to map internal enum name into user space. What if you refactor your enum value? So I suggest you to take a look at this <a href="http://www.codeproject.com/KB/cs/LocalizingEnums.aspx" rel="nofollow noreferrer">article (Localizing .NET Enums)</a>. Using technique described in this article, you can not only replace '_' with spaces, but also make different enum representation for different languages (using resources).

blocks|key|4402|text|试试这个。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4403|comboBox1.DataSource+=+Enum.GetValues(typeof(MyEnum))

comboBox1.ValueMember+=+"Value";|code-block|syntax|javascript|4404|描述，我更倾向于使用“...although”属性(根据Steve+Crane的回答)。|4405|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

Try this...

<pre><code>comboBox1.DataSource = Enum.GetValues(typeof(MyEnum))
 .Cast&lt;MyEnum&gt;()
 .Select(e =&gt; new { Value = e, Description = e.ToString().Replace("_"," ") })
 .ToList();
comboBox1.DisplayMember = "Description";
comboBox1.ValueMember = "Value";
</code></pre>

...although, I would be more inclined to use a "Description" attribute (as per Steve Crane's answer).

blocks|key|4934|text|我喜欢凯尔西的答案，尽管我会使用除了'e‘之外的另一个变量，比如'en’，所以这个答案可以用在麻烦较少的事件处理程序中；事件处理程序中的'e‘往往是EventArgs参数。至于LINQ和IEnumerable方法，在我看来，对于.NET+3.5的非WPF+ComboBoxes来说，它似乎更加复杂和困难。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|4935|entityMap^0|22|9|2L|B|3K|8|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]|$9|K|A|L|B|C]|$9|M|A|N|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|O|8|@]|D|@]|E|$]]]|G|$]]

I like Kelsey's answer although I would use another variable other than 'e' such as 'en' so the answer can be used in event handlers with less hassle; 'e' in event handlers tends to be the <code>EventArgs</code> argument.
As for the LINQ and <code>IEnumerable</code> approach, it seems to me to be more complex and difficult to adapt for non-WPF <code>ComboBox</code>es with .NET 3.5

I have an enum, example:

<pre><code>enum MyEnum
{
My_Value_1,
My_Value_2
}
</code></pre>

With :

<pre><code>comboBox1.DataSource = Enum.GetValues(typeof(MyEnum));
</code></pre>

But now my question: How can I replace the "_" with " " so that it becomes
items with spaces instead of underscores? And that a databound object still
works

我有一个枚举示例：enum MyEnum{My_Value_1,My_Value_2}通过以下方式：comboBox1.DataSource = Enum.GetValues(typeof(MyEnum));但现在我的问题是:如何将"_“替换为”“，使其成为带有空格而不是下划线的项？并且数据绑定对象仍然有效
