返回數字月份作爲字符串從日期

Question

我試圖從DateTime值獲取數字月份作爲字符串，而是我獲取MonthName，dayOfMonth。這裏是我的代碼：

string columnDate = "7/1/2003 12:00:00 AM"; 
string datePart = "M"; 
DateTime newDate = DateTime.Parse(columnDate); // 7/1/2003 12:00:00 AM as date 
dateToReturn = newDate.ToString(datePart); 
// dateToReturn is set to "July 01". It's supposed to be "7" 

我在做什麼錯？

Answer 1

何不乾脆

dateToReturn = newDate.Month.ToString(); 

或

dateToReturn = newDate.Month.ToString("D2"); 

有一個與前導零格式的月份部分。

Answer 2

dateToReturn = String.Format("{0:M}",Convert.toDateTime(newDate));
