PInvoke a C++ unsigned char [][] to C#?

[linuxfedora]

The C++ structure like that:

typedef struct d_setting
{
unsigned short setting1;
unsigned char name[100][200];
}D_SETTING;

typedef struct d_config
{
unsigned short data;
D_SETTING setting;
}D_CONFIG;

And i tried to call the C++ function by creating the corresponding structure in C# like:

[StructLayout(LayoutKind.Sequential)]
public struct D_SETTING
{
public ushort setting1;
public byte[][] name;
}

[StructLayout(LayoutKind.Sequential)]
public struct D_CONFIG
{
public ushort data;
public D_SETTING setting;
}

But the name is not correct, the program crash..
How could i create the structure for unsigned char[][] in C++??
Thanks.
