Marshaling ushort[,] multidimensional array in C# -


i've inherited code need interface with. there marshaled command want call c#. code call looks this;

[dllimport(dll_path, charset = charset.ansi, callingconvention = callingconvention.stdcall)]     public static extern void readtable([marshalas(unmanagedtype.lparray)] ushort[,] buffer);

so 'readtable' command fills in multidimensional array 'buffer'.

i'm not able well, here (non-compiling) attempt;

ushort[,] mytable = new ushort[5,100];   // multidimensional array  unsafe {   fixed (ushort* inputptr = &mytable[0, 0])   {       readtable(inputptr);   } }

obviously not compiling, i'm of newbie fix error.

i want declare;

fixed(ushort[,]* inputptr = &mytable)

but nonsense.

anyone understand plight? heaps!

try this:

ushort[,] mytable = new ushort[5,100]; readtable(mytable);

unless readtable keeps pointer after returns, marshaler's pinning , unpinning array work fine you.
