推荐答案

这样简单:

结构System.DateTime具有定义的"-"(减法运算符)；其返回类型为System.TimeSpan.

请参阅 http://msdn.microsoft.com/en-us/library/system.datetime.aspx [^ ] .

这应该足够了.

不要转换"任何东西.您需要使用System.DateTime结构，而不是它的字符串表示形式.您仅应在屏幕上显示时间数据时创建字符串表示形式.在这种情况下，您只需要根据线程的当前UI文化或仅自定义适当的格式即可.

请参阅此处的System.DateTime: http://msdn.microsoft.com/en-us/library/system.datetime.aspx [^ ].
有关格式，请参见:
http://msdn.microsoft.com/en-us/library/az4se3k1.aspx [ ^ ]，

This as simple as this:

The structure System.DateTime has "-" (subtraction operator) defined; its return type is System.TimeSpan.

See http://msdn.microsoft.com/en-us/library/system.datetime.aspx[^].

This should be more then enough.

Do not "convert" anything. You need to work with System.DateTime structure, not with string representation of it. You only should create string representation when you show time data on screen. In this case you just need to appropriate format, based on current UI culture of your thread or just custom.

See System.DateTime here: http://msdn.microsoft.com/en-us/library/system.datetime.aspx[^].
For formatting, see:
http://msdn.microsoft.com/en-us/library/az4se3k1.aspx[^],
