C# 0 The Complete Reference

{

 and end with a 

}

. This is why those 

lines in the program don’t end with a semicolon. Blocks provide a mechanism for grouping 

statements and are discussed later in this chapter.

The first 

}

 in the program ends 

Main( )

, and the last 

}

 ends the 

Example

 class definition.

One last point: C# is case-sensitive. Forgetting this can cause serious problems. For 

example, if you accidentally type 

main

 instead of 

Main

, or 

writeline

 instead of 

WriteLine

,

the preceding program will be incorrect. Furthermore, although the C# compiler 

will

 compile 

classes that do not contain a 

Main( )

 method, it has no way to execute them. So, had you 

mistyped

Main

, you would see an error message that states that 

Example.exe

 does not have 

an entry point defined.
