How to run a C# code in batch file?

Write your C# program and compile it as an exe program. In your batch file simply call it. If you need some value from the program use the return statement to return an integer.

Note: all code is untested, pseudo code and given for examples only. Syntax errors abound.

If you need to pass parameters to your C# program simply pass them when you call the program.

@echo off set Parm2=Parameter2 MyCSharpProgram.exe %1 %Parm2% Parameter3 if (errorlevel 2) GOTO label2 if (errorlevel 1) GOTO label1 goto end label1: rem do something here based an returning a value of 1 GOTO end label2: rem do something here based on returning a value of 2 GOTO end rem yeah, above line not needed but I always add it to document what I'm doing. :end echo Thank you for your support.
