It is possible to pass come compiler  options directly to the code compiler (e.g. Microsoft C# compiler csc.exe) directly from the script code:

options - compiler options as per csc.exe compiler command line interface.

Sample

The following example demonstrates how to define a compiler compiler symbol to be used for the conditional compilation.

static string code = @"using System;                         public class Script                         {                             public static void Print(string greeting)                             {                             #if USE_TIMESTAMP                                  Console.Write(DateTime.Now.ToString() + "":"");                             #endif                                                                  Console.WriteLine(greeting);                             }                          }"  ...  //executing code with USE_TIMESTAMP defined  Print = CSScript.LoadCode("//css_co /define:USE_TIMESTAMP;\n" + code)                  .GetStaticMethod();
