UrlEncode and character "*"

[Anne]

To ensure a filename (entered by a user) does not contain any special
characters, I use the "UrlEncode" method:
string FileName = System.Web.HttpUtility.UrlEncode(textBox.Text);

Unfortunately, the character "*" is not encoded so I have an error
writing on disk if the filename contains a "*".

Is there another C# method that handles all special characters,
including the "*" ?

You should look at using a regular expression validator to allow only the
submission of alpha chars? That way you wont have to worry about the
encoding. Also, if you cant do that then use replace to change any invalid
chars to underscores so you would have a valid filename.

Hello,

I have this link for you:

HttpUtility.UrlEncode encodes an URL string so it is not misunderstood, and
is not used for the filesystem.
