Update your question with the code you are using. There are TONS of possibilities.

What line does the error appear on? In what method did you put the code in (e.g., page load, form load, button click)?

You didn't set the password. That may be one of the reasons for an error. Also, remove the try/catch to see the line number the error is occurring on (or look at the stack trace in the exception.

Solution 1

There is an object that you did not initialize before you tried to use it.

Without seeing your code that corresponds to the error line number, we won't be able to help more than that.

Chances are you've got some copy-and-pasted code that you didn't fully copy, you're missing the = new SomeObject().

Cheers.

You're doing it wrong.

I know, my answer might seem vague, or even obtuse, but the quality of the question dictates the quality of the ansewr.
