How to execute C# code?

 

In this chapter we are going to tell you that “how a code written in C# language is executed?”. In the previous chapter we have told you that C# program can be written in Notepad as well as in Visual Studio 2010 IDE. So here we are going to explain the procedure of execution of C# code written in both Notepad and Visual Studio 2010 IDE one by one:

 

Execution of C# code written in Notepad

 

    • Write the following code in the Notepad:
using System;
namespace SampleApplication
{
class Sample
{
static void Main(string[] args)
{ /* my first program in C# */
Console.WriteLine(“Sample Program”);
Console.ReadLine();
}
}
}

    • Now save the above code in any location where you want to save it as “Sample.cs”.
    • Now Go to Start->All Programs->Microsoft Visual Studio 2010->Visual Studio Tools->Visual Studio 2010 Command Prompt.
    • Now set the path of command prompt with the location where you saved your program.
    • Now compile your program by writing following command:
D:> csc sample.cs

    • This will give some information about the version and .NET Framework.. If there is any error then it will produce the error message.
    • Now to run the application write the following command:
D:>sample

    • This will produce the output as given below:

Execution of C# code written in Visual Studio 2010 IDE

 

    • Open Microsoft Visual Studio 2010.
    • Now go to File->New Project.
    • This will open a “New Project dialog” box select Visual C# language and Console Application from the pane and give the name to the project as Sample and press OK.
    • Visual Studio 2010 IDE will open a editor with some previously written code remove that code and add the following code in that editor:
using System;
namespace SampleApplication
{
class Sample
{
static void Main(string[] args)
{ /* my first program in C# */
Console.WriteLine(“Sample Program”);
Console.ReadLine();
}
}
}

    • Now press F5 key this will give the following output:
