String Concat Function (C#.net)

Concatenates two specified instances of String and returns the new string that contains both the concatenated strings.

For example:

               

      string strOne = "Osama";

      string strTwo = "Maverick";

      MessageBox.Show(string.Concat(strOne,strTwo));

   

   Output:

            OsamaMaverick

If you write this:

 

  MessageBox.Show(strOne + strTwo);

Then Output would be the same:

      

    Output:

            OsamaMaverick

Another example:

  

            string strOne = "1";

            string strTwo = "2";

            MessageBox.Show(strOne + strTwo);

   Output:

            12 (because it concatenates and cant add them together)

 If you write this:

            

            string strOne = "1";

            string strTwo = "2";

           

            //Convering both strings to integer type

            int intToStr = int.Parse(strOne);

            int intToStr2 = int.Parse(strTwo);

            //Add them

            int result = intToStr + intToStr2;

            //Displays the addition result

            MessageBox.Show(result.ToString());

  

   Output:

            3

 Or can write like this:

            //Direct convert to int and displays

            MessageBox.Show((int.Parse(strOne) + int.Parse(strTwo)).ToString());

  Output:

            3
