按位桶移位的问题在C#中向左和向右旋转 [英] Problem with Bitwise Barrel Shift Rotate left and right in C#

问题描述

在C ++中，我有这样的代码.

In C++ I have code like this.

    static UInt32 rol(UInt32 value, UInt32 bits)
    {
        bits &= 31;
        return ((value << bits) | (value >> (32 - bits)));
    }

    static UInt32 ror(UInt32 value, UInt32 bits)
    {
        bits &= 31;
        return ((value >> bits) | (value << (32 - bits)));
    }

在C#中看起来如何?我想同样的方式..唯一的问题

how would it look in C#? I think the same exact way.. only problem

错误2运算符'>>'无法应用于类型'uint'和'uint'的操作数
错误3运算符'>>'无法应用于类型'uint'和'uint'的操作数
错误1运算符'<<'不能应用于类型为'uint'和'uint'的操作数
错误4运算符'<<'不能应用于类型为'uint'和'uint'的操作数

Error 2 Operator '>>' cannot be applied to operands of type 'uint' and 'uint'
Error 3 Operator '>>' cannot be applied to operands of type 'uint' and 'uint'
Error 1 Operator '<<' cannot be applied to operands of type 'uint' and 'uint'
Error 4 Operator '<<' cannot be applied to operands of type 'uint' and 'uint'

推荐答案

对于移位运算符，右侧变量应使用int类型.

You should use int type for the right side variable in shift operators.
