Regex question
-
I hace some code which starts:
if (textBox1.Text.Length > 0) { String pat = "*.csv"; Regex r = new Regex (pat, RegexOptions.IgnoreCase); Match m = r.Match(textBox1.Text); if (m.Success) { GetCSV(textBox1.Text); }which is giving me the error: "parsing "*.csv" - Quantifier {x,y} following nothing." What am I doing wrong please? -

What am I doing wrong please?Everything? Regex pattern patching is not as simple as "*.xxx" for file name: '*' means "repeated zero or more times" and '.' means any character. If you are trying to match the entire text box with a wild card filename, then why not just do:
if (textBox1.Text == "*.csv")
{
...
}since that will work.

What am I doing wrong please?Or something like
if ( textBox1.Text.EndsWith ( ".csv" ) ) ...But I would likely use a System.IO.FileInfo and check its Extension property.
