StreamWriter generate IOException Unable to find the specified file

Question

I have the following code:

using (StreamWriter writer = new StreamWriter(filename, true))
{
   writer.WriteLine(mydata);
}

that from time to time generate this error: IOException.Message = "Unable to find the specified file" .

The filename string is specified by the user and can be a network location like:

\\mycorp\Shared\Data.xml

And mydata variable is a string too.

Is it possible that this code will generate a FileNotFoundException ?

The answer to the question "Is it possible that this code will generate a FileNotFoundException ?" is: No.

I suggest checking where the exception is coming from. It should give a line number in the exception stack trace.
