How can I split a string with a string delimiter? [duplicate]

I have this string:

My name is Marco and I'm from Italy

I'd like to split it, with delimiter is Marco and, so I should get an array with

My name at [0] and
I'm from Italy at [1].

How can I do it with C#?

I tried with:

.Split("is Marco and")

But it wants only a single char.

Solution 1:

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

If you have a single character delimiter (like for instance ,), you can reduce that to (note the single quotes):

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

Solution 2:

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

Consider the spaces surronding "is Marco and". Do you want to include the spaces in your result, or do you want them removed? It's quite possible that you want to use " is Marco and " as separator...

Solution 3:

You are splitting a string on a fairly complex sub string. I'd use regular expressions instead of String.Split. The later is more for tokenizing you text.

For example:

var rx = new System.Text.RegularExpressions.Regex("is Marco and");
var array = rx.Split("My name is Marco and I'm from Italy");

Solution 4:

Try this function instead.

string source = "My name is Marco and I'm from Italy";
string[] stringSeparators = new string[] {"is Marco and"};
var result = source.Split(stringSeparators, StringSplitOptions.None);
