我已经解决了这个问题。在将日期插入表格之前，以及每当我想根据sysytem更改格式的地方时，我都会通过此代码更改它并且

  String  date = MyDate.Text; 
 DateTime paydate = Convert.ToDateTime（date，System.Globalization.CultureInfo.GetCultureInfo（  hi-IN 跨度>）DateTimeFormat）; 

I am using DateTimePicker , i set it's customFormat property to dd/MM/yyyy. In the system i have the format M/d/yyyy. How can i make the DateTimePicker independent from the systems one.

I have tried statements like

    MyDate.Format = DateTimePickerFormat.Custom;
    MyDate.CustomFormat="dd/MM/yyyy";
but it's doesn't work.

I have solved this . Before insert date in to table, and every where when i want to change format according sysytem then i changed it by this code and

String date = MyDate.Text;
DateTime paydate =Convert.ToDateTime(date,System.Globalization.CultureInfo.GetCultureInfo("hi-IN").DateTimeFormat);
