How do I grab what is written to console with CSharpCodeProvider

Question

I use following to compile C# in runtime:

CompilerParameters parameters = new CompilerParameters
        {
            GenerateInMemory = true,
            GenerateExecutable = true,
            IncludeDebugInformation =  true
        };


        // True - memory generation, false - external file generation
        // True - exe file generation, false - dll file generation

        var res = pro.CompileAssemblyFromSource(parameters,
            code);

        Assembly assembly = res.CompiledAssembly;
        Type program = assembly.GetType("First.Program");
        MethodInfo main = program.GetMethod("Main");
        var invoke = main?.Invoke(null, null);

res.Output is an empty list, and If the code has Console.WriteLine(), It gets written to main application's console, however; I wanna grab what is written.

You also should check res.Errors. If there are errors, then they will be there instead. If both Errors and Output are empty, then you may have had a successful compilation without any output. Check: cr.NativeCompilerReturnValue.ToString()

There are no errors, and it writes to parent application's debug, but I wanna fetch it instead. – Talha Talip Açıkgöz Oct 21 '17 at 16:41
@TalhaTalipAçıkgöz Not sure what would cause that. You could use a debug listener: https://msdn.microsoft.com/en-us/library/system.diagnostics.debug.listeners(v=vs.110).aspx – AaronLS Oct 21 '17 at 16:45
I will take a look, but I think there should be a better way. – Talha Talip Açıkgöz Oct 21 '17 at 16:47
I made it an external file, and with a process, read the stream; still thanks for the help. – Talha Talip Açıkgöz Oct 21 '17 at 19:39
