为什么我得到String未被识别为有效的DateTime错误？

Question

尝试解析s我得到了异常

  

＆＃34; String未被识别为有效的DateTime＆＃34;

string s = @"07/24/2014 14:46:47";
DateTime dt = DateTime.Parse(s);

Answer 1

System.Globalization.CultureInfo provider =
   System.Globalization.CultureInfo.InvariantCulture;
string dateTimeString = @"07/24/2014 14:46:47";
string dateTimeFormat = @"MM/dd/yyyy HH:mm:ss";
var dateTime = DateTime.ParseExact(dateTimeString, dateTimeFormat, provider);

有用的链接：

• DateTime.ParseExact Method on MSDN
• Standard Date and Time Format Strings on MSDN
• The "/" custom format specifier on MSDN
• Using the Escape Character on MSDN

Answer 2

DateTime myDate = DateTime.ParseExact("7/24/2014 14:46:47", 
  "MM/dd/yyyy HH:mm:ss", System.Globalization.CultureInfo.InvariantCulture);

Answer 3

正如Sayse和Sriram Sakthivel所说，你需要传递字符串所在的格式

DateTime.ParseExact(s, "MM-dd-yyyy HH:mm:ss", CultureInfo.InvariantCulture);
