Note

The options sent to the command-line compiler (as well as most other command-line tools) can be pre-

fixed with either a dash (

-?

) or a slash (

/?

).

To compile TestApp.cs into a console application named TestApp.exe, change to the directory

containing your source code file:

cd C:\CscExample

and enter the following command set (note that command-line flags must come before the name of

the input files, not after):

csc /target:exe TestApp.cs

Here I did not explicitly specify an /out flag, therefore the executable will be named TestApp.exe,

given that TestApp is the name of the input file. Also be aware that most of the C# compiler flags

support an abbreviated version, such as /t rather than /target (you can view all abbreviations by

entering csc -? at the command prompt).

csc /t:exe TestApp.cs

Furthermore, given that the /t:exe flag is the default output used by the C# compiler, you

could also compile TestApp.cs simply by typing

csc TestApp.cs

TestApp.exe can now be run from the command line as shown in Figure 2-2.
