如何使两个WORD变为DWORD

Question

        short val1 = short.MaxValue;
        short val2 = short.MaxValue;

        int result = val1;
        result |= val2 << 16;

        Console.WriteLine( "Result =\t" + result );         //2147450879
        Console.WriteLine( "Expected =\t" + int.MaxValue ); //2147483647

Answer 1

short已签名,因此最大值为0x7FFF.连接这导致0x7fff7fff而不是0x7fffffff2147450879.所以你看到的实际上是正确的.
