Question

Awhile ago I asked you another question(Click here to view the question).

This is my problem when using that source file you gave me:

public unsafe struct tPacket_5000_E {     public Int16 size;     public Int16 opcode;     public byte securityCount;     public byte securityCRC;     public byte flag;     fixed byte blowfish[8];  //Please NOTE THIS     public Int32 seedCount;     public Int32 seedCRC; public fixed Int32 securityseed[19]; }; 

The struct is marked as ‘Unsafe’ ,because of the blowfish array.I couldn’t find any other way to declare an array inside structure.

The problem: When I parse the packet into that structure,the function doesn’t put anything in blowfish[8],it’s like it doesnt exist.Instead it puts the bytes in seedCount and seedCRC instead in blowfish or securityseed. They are always empty

This is my code:

 tPacket_5000_E packet = new tPacket_5000_E();  packet = (tPacket_5000_E)CDynamicCastHelper.CastIntoFields(packet, data2, CastOptions.ReverseDWord | CastOptions.ReverseDWord); 

Why it doesn’t work for arrays? Is it ,because it’s unsafe?

Thanks in advance!

Look at MarshalAs attribute instead.
