The Substring() method in C# is used to retrieve a substring from this instance. The substring starts at a specified character position and continues to the end of the string.SyntaxThe syntax is as follows -public string Substring (int begnIndex); public string Substring (int begnIndex, int len);Above, begnIndex is the zero-based starting character position of a substring in this instance.
