How to create .exe file with csc?

I open cmd.exe and write:

C:\Users\user\Desktop\Project2

It works and shows me my console application, but when I write:

C:\Users\user\Desktop\csc Project2

or

C:\Users\user\Desktop\csc.exe Project2

It doesn't work(

I have done the same thing with command prompt and visual studio command prompt.

So, what can I do to create .exe file in this way?
