推荐答案

这是因为您正在解析字符串而未指定表示时间的字符串的确切格式，这与默认情况下预期的不同。请使用 System.String.DateTime.ParseExact 或之一准确指定格式.System.String.DateTime.TryParseExact ：

请记住 ParseExact 抛出异常是识别失败，所以您应该处理异常，或使用 TryParseExact 表单。



格式说明符请参阅：

This is because you are parsing the string without specifying exact format of the string representing time, which is not the same which is expected by default. Please specify the format exactly using one of the System.String.DateTime.ParseExact or System.String.DateTime.TryParseExact:
http://msdn.microsoft.com/en-us/library/system.datetime.aspx[^].

Remember that ParseExact throws exception is the recognition is failed, so you should either handle the exception, or use the TryParseExact form.

For format specifiers, please see:
