public static void Main() {
Console.WriteLine("A simple C# program.");
}
}

class const continue decimal default
delegate do double else enum
event explicit extern false finally
fixed float for foreach goto
if Implicit In Int Interface
Internal Is lock long namespace
new null object operator out
override params private protected public
readonly ref return sbyte sealed
short sizeof stackalloc static string
struct switch this throw true
try typeof uint ulong unchecked
unsafe ushort using virtual void
volatile while

Using csc.exe, the C# Command-Line Compiler
To create and run programs using the C# command-line compiler:
- Enter the program using a text editor.
- Compile the program.
- Run the program.
Compiling the Program
C:\>csc Example.cs
Prior to running csc.exe, you may need to run the batch file vcvars32.bat, which is typically found in the //Program Files/Microsoft Visual Studio.NET/Vc7/Bin directory.
- The name of a C# program is arbitrary
- By convention, C# programs use the .cs file extension
