将布尔值转换为长整数 [英] convert a bool into long

问题描述

我尝试将布尔值0和1转换为long

像-0和-1

i try to a bool value 0 and 1 convert in long

like -0 and -1

bool flag=false;

long iApplyTilde = (long) -(flag > false);

请帮助

预先感谢

please help

thanks in advance

推荐答案

您似乎正在尝试根据 flag 的值为字符分配代字号.您为什么要转换为冗长的麻烦?只需在 if 语句中测试 flag 的值，然后采取相应措施即可.如果需要，

It appears that you''re trying to assign a tilde to a character, based upon the value of flag. Why are you going to the trouble of converting to a long? Just test the value of flag in an if statement, and act accordingly. If you must,

long lflag = 0;
if (flag) lflag=1;
long iApplyTilde = lflag;

但我认为没有必要进行所有这些额外工作.

but I see no reason for all that extra work.

第一:-0不存在

first: -0 does noet exist

bool flag = true;
long iApplyTilde = Convert.ToInt64(flag) *-1;
Console.WriteLine(iApplyTilde);
Console.ReadKey(true);

这可能会有所帮助，

It might be helpful,

static void Main(string[] args)
{
    Console.WriteLine(GetLongValue(((DateTime.Now.Second % 2) == 0)));
}

private static Int64 GetLongValue(bool flag)
{
    return -Convert.ToInt64(flag);
}
