比较: public static extern int comp2(byte[] a, byte[] b, int count);
[DllImport("msvcrt.dll", CallingConvention = CallingConvention.Cdecl, SetLastError = false)] static extern int memcmp(byte[] b1, byte[] b2, UIntPtr count); [DllImport("msvcrt.dll", CallingConvention = CallingConvention.Cdecl, SetLastError = false)] static extern int memcmp(IntPtr ptr1, IntPtr ptr2, int count); [DllImport("msvcrt.dll", CallingConvention = CallingConvention.Cdecl, SetLastError = false)] static extern unsafe int memcmp(void* ptr1, void* ptr2, int count); 复制: [DllImport("msvcrt.dll", EntryPoint = "memcpy", CallingConvention = CallingConvention.Cdecl, SetLastError = false)]
public static extern IntPtr memcpy(IntPtr dest, IntPtr src, UIntPtr count); [DllImport("msvcrt.dll", EntryPoint = "memcpy", CallingConvention = CallingConvention.Cdecl, SetLastError = false)] public static extern IntPtr MemCopy(byte[] dest, byte[] src, UIntPtr count); 还有一个复制的方法: System.Runtime.InteropServices.Marshal.Copy(buffer, bytes, 0, size)
