You can use the split() method of String class from JDK to split a String based on a delimiter e.g. splitting a comma-separated String on a comma, breaking a pipe-delimited String on a pipe, or splitting a pipe-delimited String on a pipe.
Use the Split method when the substrings you want are separated by a known delimiting character (or characters). Regular expressions are useful when the string conforms to a fixed pattern. Use the IndexOf and Substring methods in conjunction when you don't want to extract all of the substrings in a string.
Split(char[]) Method This method is used to splits a string into substrings that are based on the characters in an array. Syntax: public String[] Split(char[] separator); Here, separator is a character array that delimits the substrings in this string, an empty array that contains no delimiters, or null.
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(',');
.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...
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");
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);
