TimeSpan到整数 [英] TimeSpan to integer

问题描述

如何将TimeSpan 对象转换为等效的整数值?谢谢.

How can I convert a TimeSpan object to an equivalent integer value? Thank you.

推荐答案

我知道这个问题早已被标记为答案了，但是我认为从另一个角度来看这可能很有趣. .


首先TimeSpan在内部表示为long(只需获取TimeSpan.Ticks属性，鲍勃是您的叔叔)，因此它已经是整数类型.

其次，您可以将其转换为十进制，仅用于编码练习:

I know this has halready had a response marked as the answer, but I was thinking it might be fun to look at it from another viewpoint...


First TimeSpan is represented internally as a long (just get the TimeSpan.Ticks property, and Bob''s your uncle), so it''s already an integer type.

Second, you could convert it to a decimal, just for the coding exercise:

public static class ExtensionMethods
{
    //-------------------------------------------------------------
    public static decimal ToDecimal(this TimeSpan span)
    {
        decimal spanSecs = (span.Hours * 3600) + (span.Minutes * 60) + span.Seconds;
        decimal spanPart = spanSecs / 86400M;
        decimal result = span.Days + spanPart;
        return result;
    }
    //-------------------------------------------------------------
    public static TimeSpan ToTimeSpan(this decimal value)
    {
        int days = Convert.ToInt32(Math.Ceiling(value));
        value -= days;
        int time = Convert.ToInt32(value * 86400M);
        TimeSpan result = new TimeSpan(1, 0, 0, time, 0);
        return result;
    }
}

用法如下:

Usage would be thus:

TimeSpan span          = new TimeSpan(0,12,0,0,0);
decimal  spanAsDecimal = span.ToDecimal();
TimeSpan span2         = spanAsDecimal.ToTimeSpan();

有用?也许吧，也许不是.编码有趣吗?是的.

警告:这无需考虑毫秒，但添加起来很容易.

Useful? Maybe, maybe not. Fun to code? Yep.

Caveat: This doesn''t take milliseconds into account, but it would be easy to add.

我将不得不假设标签是错误的，并且您正在考虑.net System.TimeSpan结构.

如果是，则 System.TimeSpan.Ticks [

I''ll have to assume that the tag is wrong, and that you are thinking of the .net System.TimeSpan structure.

If you are, then System.TimeSpan.Ticks[^] is your answer.

int intValueLow32Bits = Convert.ToInt32( 0x00000000FFFFFFFF & ticksAsLong );
int intValueHigh32Bits = Convert.ToInt32( ticksAsLong >> 32 );

如果您正在考虑其他问题，我将需要更多信息...
