How to Add Hyphens in C Sharp

The C# language has several string functions that let you append characters to existing strings. You use the "+=" notation to add a hyphen to a C# string. You use this notation when you want to build a string of characters that you later use to store data to a database or display the information to the user.

Instructions

1. Open the Visual Studio software from the Microsoft Windows "Start" menu. Open your C# project after VS loads.

2. Double-click the ".cs" file you want to use to append the hyphen to the string. If you do not already have a string you want to use, the following code shows you how to create a string:

   string mystring = string.Empty;

3. Append the hyphen to the string. The following code takes the existing string content and appends a hyphen to the text:

   mystring = "some text here";
   mystring += "-";

4. Display the output. In this example, the output displays "some text here-" in the console. The following code shows you how to display the results:

   System.Console.WriteLine(mystring);
