How can I check at runtime whether a C# application is a Windows application or a console application?
I want to write a generic output library (output to textbox or console when console app).
For that reason, if I could check whether it is a asp application would be useful, too.
I think you may be attacking the problem in the wrong way. Without knowing more about what you are doing here is what I’d suggest:
Create an interface called something like IOutputWriter with a Write(…) method. Then create an implementation for each environment (ConsoleOutputWriter, TextboxOutputWriter, etc…). Each environment can use the appropriate implementation since they know what type of app they are.
