Using Unmanaged C++ Structure in C#

[VFaul]

How do I convert the following unmanaged C++ structures in C# (which I will be using in PInvoke calls)? typedef struct { unsigned char Camera; unsigned char DecoderId; } VIDEO_SEQ_CMD; typedef struct { int CompressionMode; VIDEO_SEQ_CMD VideoSequence[64]; } USER_CONFIG_DATA; I think the following works for the first struct. I'm not sure how to handle the array in the second struct. [StructLayout(LayoutKind.Explicit, CharSet = CharSet.Ansi)] public struct VideoSeqCmd { [FieldOffset(0), MarshalAs(UnmanagedType.U1)] public byte Camera; [FieldOffset(1), MarshalAs(UnmanagedType.U1)] public byte DecoderId; } Thanks!

See this... [StructLayout(LayoutKind.Explicit, CharSet = CharSet.Ansi)] public struct UsserConfigData { [FieldOffset(0), MarshalAs(UnmanagedType.I4)] public int CompressionMode; [FieldOffset(1), MarshalAs(UnmanagedType.ByValArray, SizeConst=16, ArraySubType=UnmanagedType.Struct)] VideoSeqCmd [] VideoSequence; }
