Interop C to C# RRS feed

  • Question

  • Hello. Could you specify links to clear rules on how the laws of the unmanaged types is displayed in the language with the c # types.  I'm trying to write a managed wrapper for c # library and very foul. Here is a simplified example, for which I can't write wrapper:
    Sorry for the terrible knowledge of English, Russian Forum answers No.
    #define LONGLONG long long
    typedef struct
       char* filename;
       char zcmptype[12];
    typedef struct
       LONGLONG* headstart;
       TColumn* tableptr;
    How to implement this definition in c #?

  • [StructLayout(LayoutKind.Sequential, CharSet=CharSet.Ansi)]
    public struct TColumn {
        public string filename;
        [MarshalAsAttribute(UnmanagedType.ByValTStr, SizeConst=12)]
        public string zcmptype;
    public struct FitsFile {
        public System.IntPtr headstart;
        public System.IntPtr tableptr;
