How to get DateTime month in upper case?

Question

I am using the following to format a DateTime:

DateTime CusDate = dateTimePicker1.Value;
string Date = CusDate.ToString("ddMMMyyyy");

I am getting the format such that "Nov" is not in upper case:

04Nov2011

But I want the format of "Nov" in capital letters, like this:

04NOV2011

This is because I am downloading a file from a website programatically which is in this format.

Answer 1

Just do the string ToUpper():

    DateTime CusDate = dateTimePicker1.Value;
    string Date = CusDate.ToString("ddMMMyyyy").ToUpper();
