C# does not support methods that use variable length arguments (varargs).
The compiler automatically resolves calls to this method to the same method that uses a parameter array.

Parameters

String.Concat(Object, Object, Object, Object) has the following parameters.

• arg0 - The first object to concatenate.
• arg1 - The second object to concatenate.
• arg2 - The third object to concatenate.
• arg3 - The fourth object to concatenate.

Returns

Example

The following example illustrates the use of the Concat(Object, Object, Object, Object) method to concatenate a list of variable parameters.

//from w  w w  .j  ava2s .  c  om
using System;
using System.Collections;

public class Example
{
   public static void Main()
   {
      string[] words = { "A", "B", "C", "D" };

      string scrambledWord = String.Concat(words[0], words[1], 
                                              words[2], words[3]);
      Console.WriteLine(scrambledWord);

   }
}

The code above generates the following result.
