How to Split Strings with Multi-Character Delimiters in C#?

Use multi-character delimiter to split string in C#

When splitting a string using the Split method in C#, the default behavior is to use a single character delimiter. However, in some cases you may need to use a delimiter that consists of multiple characters, such as a word.

To do this, you can specify a delimiter string when calling the Split method. The following example demonstrates how to split the string "This is a sentence" using the delimiter "is":

<code class="language-csharp">string source = "This is a sentence";
string[] stringSeparators = new string[] { "is" };
string[] result = source.Split(stringSeparators, StringSplitOptions.None);

foreach (string s in result)
{
    Console.Write("'{0}' ", String.IsNullOrEmpty(s) ? "" : s);
}</code>

This code will produce the following output:

<code>'This ' 'a sentence' ' '</code>

StringSplitOptions.None argument indicates that the split should not remove empty elements from the resulting array. If you want to remove empty elements, you can specify StringSplitOptions.RemoveEmptyEntries instead.
