Converting a C++ struct to an C# struct
Hello,
I am new to C# and have a problem implementing an unmanaged .dll into an C# project which needs managed code.
The .dll is already accepted and also the correct entry points are found, the last problem seems to been the conversion from an C++ struct to an C# struct.
Here is the C++ code:
typedef struct SymbolRequest {
WORD SecurityType;
BYTE ExchangeId;
char Symbol[20];
DWORD Flags;
} SymbolRequest;
Of course I have already tried it by my own for several days but it always throws an exception stating that something tries to write or read in secured memory --- I expect that my conversions are wrong. See what I got in C#:
[StructLayout(LayoutKind.Sequential)]
public struct SymbolRequestStruct
{
public short SecurityType;
public byte ExchangeId;
[MarshalAs(UnmanagedType.ByValTStr, SizeConst = 20)]
public string Symbol;
public uint Flags;
}
Something has to be wrong and it would be nice if someone can help me since I am having the problem since more than three days.
Thank you in advance.
JB
