I've wrote this little method to achieve the goal in the subj., however, is there more efficient (simpler) way of doing this? who will search for this like I did.
var fileName = new System.Text.StringBuilder();
fileName.Append("*Bad/ :, Filename,? ");
// get rid of invalid chars
while (fileName.ToString().IndexOfAny(System.IO.Path.GetInvalidFileNameChars()) > -1)
{
fileName = fileName.Remove(fileName.ToString().IndexOfAny(System.IO.Path.GetInvalidFileNameChars()), 1);
}
?

I'm trying to remove extraneous characters like quotes, commas, etc from my dataset. I get the fact in the standard way of doing things in your code behind you simply go
string data = data.replace(",",""); or something like this. However, a datasource doesn't seem to give me that capability. What can I do to make it do this?

If I manually rename the file and remove the # symbol, the file will open ok. How do I prevent users from uploading a file with a # sign in it, or how do I strip out that symbol?
