The method concatenates arg0, arg1, and arg2 by calling the parameterless ToString method of each object; it does not add any delimiters.

string.Empty is used in place of any null argument.

The following example demonstrates concatenating three objects.

using System;
public class StringConcatExample {
 public static void Main() {
 string str = String.Concat( 'c', 32, "String" );
 Console.WriteLine( "The concatenated Objects are: {0}", str );
 }
}
   

The output is

The concatenated Objects are: c32String
