The method concatenates arg0 and arg1by calling the parameterless ToString method of arg0 and arg1; it does not add any delimiters.

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

If either of the arguments is an array reference, the method concatenates a string representing that array, instead of its members (for example, "System.String[]").

The following example demonstrates concatenating two objects.

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

The output is

The concatenated Objects are: c32
