How to read a string like ("05.10/2012 5:30:29 PM") and use it in a DateTime value ?

答

Hello

试试这个:

Hello

Try this:

DateTime myDateTime = DateTime.Parse("05.10/2012 5:30:29 PM");

或

DateTime myDateTime;
DateTime.TryParse("05.10/2012 5:30:29 PM", out myDateTime)

假设每个日期都在单独的行中，则可以使用
读取所有日期

Assuming each date is on a separate line, you can read them all with

string[] lines = File.ReadAllLines(path);

然后，您可以使用Datetime.ParseExact或DateTime.TryParseExact将每个转换为DateTime:

You can then convert each one to a DateTime using Datetime.ParseExact, or DateTime.TryParseExact:

foreach (string line in lines)
   {
   DateTime dt = DateTime.ParseExact(line, "dd.MM/yyyy h:mm:ss tt", CultureInfo.InvariantCulture);
   ...
   }

这里有一个DateTime格式代码列表:为显示-格式字符串说明 [ ^ ]
