// Allocate a new buffer (skip this if you already have one) 
byte[] buffer = new byte[256]; 
unsafe 
{ 
    // The "fixed" statement tells the runtime to keep the array in the same 
    // place in memory (relocating it would make the pointer invalid) 
    fixed (byte* ptr_byte = &buffer[0]) 
    { 
     // Cast the pointer to sbyte* 
     sbyte* ptr_sbyte = (sbyte*) ptr_byte; 

     // Do your stuff here 
    } 

    // The end of the "fixed" block tells the runtime that the original array 
    // is available for relocation and/or garbage collection again 
}

Truyền thành mảng và sau đó truyền thành byte [] sẽ là đủ.

byte [] unsigned = {0, 1, 2};

sbyte [] signed = (sbyte []) (Array) unsigned;
