How Can I Split a String in C# Using a Single Character or a String as a Delimiter?

Splitting a String with a Delimiter

In C#, the Split() method enables you to split a string into substrings based on a specified delimiter. However, by default, it only accepts a single character as a delimiter.

Splitting with a String Delimiter

To split a string using a string as a delimiter, you can specify the delimiter as an array within the Split() method. For example:

string[] tokens = str.Split(new[] { "is Marco and" }, StringSplitOptions.None);

In this case, str is the input string, and tokens will contain an array of two substrings:

• tokens[0]: "My name"
• tokens[1]: "I'm from Italy"

Simplifying for Single-Character Delimiters

If you are splitting the string using a single character delimiter, such as a comma ,, you can simplify the code as follows:

string[] tokens = str.Split(',');

This approach is more concise, especially when dealing with simple delimiters.
