Compiler Error CS1032
Cannot define/undefine preprocessor symbols after first token in file
The #define
and #undef
preprocessor directives must be used at the beginning of a program, before any other keywords, such as those used in the namespace declaration.
The following sample generates CS1032:
C#
// CS1032.cs
namespace x
{
public class clx
{
#define a // CS1032, put before namespace
public static void Main()
{
}
}
}
