Compiling and executed a c# program

If you are using Visual Studio.Net for compiling and executing C# programs, take the following steps:
1. Start Visual Studio.

2. On the menu bar, choose File, New, Project.

3. Choose Visual C# from templates, and then  choose Windows.

4. Choose Console Application.

5. Specify a name for your project, and then choose the OK button.

6. The new project appears in Solution Explorer.

7. Write code in the Code Editor.

8. Click the Run button or the F5 key to run the project. A Command Prompt window appears that contain the line Hello World.

You can compile a C# program by using the
command-line instead of the Visual Studio IDE:
* Open a text editor and add the above- mentioned code.

* Save the file as helloworld.cs

* Open the command prompt tool and go to the directory where you saved the file.

* Type csc helloworld.cs and press enter to compile your code.

* If there are no errors in your code, the command prompt will take you to the next line and would generate helloworld.exe executable file.

* Next, type helloworld to execute your program.

* You will be able to see "Hello World" printed on the screen.
