What you want to do? I mean is it ok if the final output is string?

There are multiple ways.See following code in vb.net

C#

Shared Function ConvertDateFormatForPrint(ByVal dtVal As Object) As Object
       Return Date.Parse(dtVal).ToString("dd/MM/yyyy")
End Function

1. Your format is incorrect. Change it to "dd-MM-yyyy"
2. Why do you want conversion of dt to the desired format than back to the original format? You already have both "MM-dd-yyyy" format date as well as "dd-MM-yyyy" format date.

C#

DateTime dt = System.DateTime.Now;
string format = "dd-MM-yyyy";           
string newDate = dt.ToString(format);

This works for me. Try this.

C#

lbltime.Text = System.DateTime.Now.ToShortDateString();
        string d1 = DateTime.Parse(lbltime.Text).ToString("yyyy-MM-dd");

by using this code
string dt1 = System.DateTime.Now.ToShortDateString();
string dd = DateTime.Parse(dt1).ToString("DD-MM-YYYY");
MessageBox.Show(dd);
it gives me same out put as "DD-10-YYYY"

Change your date format to this:
dd-MM-yyyy

That is because your format is wrong. Dont use "DD-MM-YYYY", use "dd-MM-yyyy". Change your format and this code will work.

try
           {
               DateTime dt = DateTime.Now;//dtiFrom.Value.Date;
               string format = "DD-MM-YYYY";            // Use this format
              // MessageBox.Show(dt.ToString(format));   // here its shows result as DD-10-YYYY
               MessageBox.Show(dt.ToString("dd-MM-yyyy"));
               DateTime dt1 = Convert.ToDateTime(dt.ToString("MM/dd/yyy"));
           }
           catch (Exception ee)
           {
               MessageBox.Show(ee.Message, "Error Message!");
           }

Your format should be as follows:

string format = "dd-MM-yyyy";
Casing is important with string formatting, you may think it strange that the month uses upper-case, but this is because lower case m and mm is used to represent minutes.

Note that the reason your output displays DD and YYYY is because any character that is not reserved as a format character will be outputted with no change. Uppercase D and Y are not reserved which is why they display in the output, just as - remains unchanged.

If you wish to output reserved format characters then you can escape them using \.
