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.

Solution 1

Just do the string ToUpper():

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

Solution 2

After you're done with the toString...

string date = date.ToUpper();

Solution 3

Use the String.ToUpper() method:

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

Solution 4

Convert the string to upper case (won't affect the numbers):

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

Simpler to add the .ToUpper() call after the .ToString("ddMMMyyyy") call, I think. Not sure if there's any actual under-the-hood differences though.

The compiler will probably optimise it anyway.

True enough. Might be interesting to compare the MSIL between the two, but for all intents and purposes it's fine either way.
