关于c#实现c++一样的位寻址
最近在学习c#，但是遇到一个union的问题，之前有一段代码是c++的,如下,怎样在c#中实现这种功能呢？望高人指点啊，不甚感激。
struct stBitType
{
unsigned int Bit0 :1;
unsigned int Bit1 :1;
unsigned int Bit2 :1;
unsigned int Bit3 :1;
unsigned int Bit4 :1;
unsigned int Bit5 :1;
unsigned int Bit6 :1;
unsigned int Bit7 :1;
};
union unBitConvert
{
struct stBitType BitValue;
unsigned char ucValue;
};
unsigned char modMult02(unsigned char x)
{
union unBitConvert Input,Output;
Input.ucValue=x;
Output.BitValue.Bit0=Input.BitValue.Bit7;
Output.BitValue.Bit7=Input.BitValue.Bit6;
Output.BitValue.Bit6=Input.BitValue.Bit5;
Output.BitValue.Bit5=Input.BitValue.Bit4;
Output.BitValue.Bit2=Input.BitValue.Bit1;
Output.BitValue.Bit1=Input.BitValue.Bit0^Input.BitValue.Bit7;
Output.BitValue.Bit3=Input.BitValue.Bit2^Input.BitValue.Bit7;
Output.BitValue.Bit4=Input.BitValue.Bit3^Input.BitValue.Bit7;
return Output.ucValue;
}
[解决办法]
public struct unBitConvert { int innerValue; public byte ucValue { get { return (byte)(innerValue & 0xff); } set { innerValue = value; } } public bool Bit0 { get { return (innerValue & 1) != 0; } set { if (value) { innerValue |= 1; } else { innerValue &= ~1; } } } public bool Bit1 { get { return (innerValue & 2) != 0; } set { if (value) { innerValue |= 2; } else { innerValue &= ~2; } } } public bool Bit2 { get { return (innerValue & 4) != 0; } set { if (value) { innerValue |= 4; } else { innerValue &= ~4; } } } public bool Bit3 { get { return (innerValue & 8) != 0; } set { if (value) { innerValue |= 8; } else { innerValue &= ~8; } } } public bool Bit4 { get { return (innerValue & 16) != 0; } set { if (value) { innerValue |= 16; } else { innerValue &= ~16; } } } public bool Bit5 { get { return (innerValue & 32) != 0; } set { if (value) { innerValue |= 32; } else { innerValue &= ~32; } } } public bool Bit6 { get { return (innerValue & 64) != 0; } set { if (value) { innerValue |= 64; } else { innerValue &= ~64; } } } public bool Bit7 { get { return (innerValue & 128) != 0; } set { if (value) { innerValue |= 128; } else { innerValue &= ~128; } } } }
