Hi Friends,

I'm new to C#.net. I need to concat the two String lists. how can i do the following?

string[] a=  new string[fileA.Count] Ex: a, b, c, d
string[] b=  new string[fileB.Count] Ex: e, f, g, h

Now I need to Combine both the lists like

string[] c = new string[fileA.Length + fileB.Length]

i want like this

c[] = {a, b, c, d, e, f, g, h}

regards
Harish Reddy

Please try this...

C#

string[] a = new string[2];
            a[0] = "a";
            a[1] = "b";
            string[] b = new string[2];
            b[0] = "c";
            b[1] = "d";
            string[] c = new string[4];

            a.CopyTo(c, 0);
            b.CopyTo(c, a.Length);


            Console.WriteLine(c.ToString());
