Replacing all the occurences of a string with new value

In a string text, if some texts which occur at many places, need to be replaced by some different value then a regular expression can be used.This can be done by using System.Text.RegularExpressions.Regex class of .NET framework.

For example suppose a string variable str contains "This is <> and it used by the regex class.The value for <> will be replaced." We want to replace all the occurences of placeholder <> with some name say "DOTNETSPIDER" then the following code will do this -

using System.Text.RegularExpressions;

class ReplaceDemo
{
   public string ReplaceName(string originalText,string name)
   {
     originalText =Regex.Replace(originalText, <>, name);
   }
}
