String.Concat Method (String[])

public static string Concat(
	params string[] values
)

The method concatenates each object in values; it does not add any delimiters.

An Empty string is used in place of any null object in the array.

The following example demonstrates the use of the Concat method with a String array.


using System;

public class ConcatTest {
    public static void Main() {

        // make an array of strings. Note that we have included spaces
        string [] s = { "hello ", "and ", "welcome ", "to ", "this ", "demo! " };

        // put all the strings together
        Console.WriteLine(string.Concat(s));

        // sort the strings, and put them together
        Array.Sort(s);
        Console.WriteLine(string.Concat(s));
    }
}
