<pre><code>string[] result = input.Split(new string[] {"\n", "\r\n"}, StringSplitOptions.RemoveEmptyEntries);
</code></pre>

This covers both \n and \r\n newline types and removes any empty lines your users may enter.

I tested using the following code:

<pre><code> string test = "PersonA\nPersonB\r\nPersonC\n";
 string[] result = test.Split(new string[] {"\n", "\r\n"}, StringSplitOptions.RemoveEmptyEntries);
 foreach (string s in result)
 Console.WriteLine(s);
</code></pre>

And it works correctly, splitting into a three string array with entries "PersonA", "PersonB" and "PersonC".

blocks|key|322265|text|这取决于你想做什么。另一种选择是使用StringReader类并使用枚举器，这对于较小的列表可能是过度杀伤力，但对于较大的字符串可能会更有效：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|322266|IEnumerable<string>+GetNextString(string+input)

}|code-block|syntax|javascript|322267|这同时支持\n和\r\n行结束。因为它返回一个IEnumerable，所以您可以使用foreach处理它，或者使用任何标准的linq扩展(ToList()、ToArray()、Where等)。|322268|例如，使用foreach|322269|var+ss+=+"Hello\nworld\r\ntwo+bags\r\nsugar";

It depends what you want to do. Another option, which is probably overkill for small lists, but may be more memory efficient for larger strings, is to use the <code>StringReader</code> class and use an enumerator:

<pre><code>IEnumerable&lt;string&gt; GetNextString(string input)
{
 using (var sr = new StringReader(input))
 {
 string s;
 while ((s = sr.ReadLine()) != null)
 {
 yield return s;
 }
 }
}
</code></pre>

This supports both <code>\n</code> and <code>\r\n</code> line-endings. As it returns an <code>IEnumerable</code> you can process it with a <code>foreach</code>, or use any of the standard linq extensions (<code>ToList()</code>, <code>ToArray()</code>, <code>Where</code>, etc).

For example, with a <code>foreach</code>:

<pre><code>var ss = "Hello\nworld\r\ntwo bags\r\nsugar";
foreach (var s in GetNextString(ss))
{
 Console.WriteLine("==&gt; {0}", s);
}
</code></pre>

I have an ASP.NET page with a multiline textbox called txbUserName. Then I paste into the textbox 3 names and they are vertically aligned:

<ul>
<li>Jason</li>
<li>Ammy</li>
<li>Karen</li>
</ul>

I want to be able to somehow take the names and split them into separate strings whenever i detect the carriage return or the new line. i am thinking that an array might be the way to go. 
Any ideas?

thank you.

How to split strings on carriage return with C#?

集成开发环境

我有一个ASP.NET页面，其中包含一个名为txbUserName的多行文本框。然后我将3个名字粘贴到文本框中，它们垂直对齐：JasonAmmyKaren每当我检测到回车符或换行符时，我希望能够以某种方式获取这些名称，并将它们拆分成单独的字符串。我在想，数组可能是最好的选择。有什么想法吗？谢谢。
