Question

I am trying to filter outout of a method, so only files with a “FF-” prefix will be returned.

My code is as follows:

 DirectoryInfo dinfo = new DirectoryInfo(@"C:\Windows\system32\tasks");
            FileInfo[] Files = dinfo.GetFiles("*.*");
            foreach (FileInfo file in Files)
            {
                listBox1.Items.Add(file.Name);
            }

Answer 1

Like this?

FileInfo[] Files = dinfo.GetFiles("FF-*.*");

Directory.GetFiles Method

Quote:

* - Zero or more characters.  
? - Exactly zero or one character. 

For example, the searchPattern string
“*t” searches for all names in path
ending with the letter “t”. The
searchPattern string “s*” searches for
all names in path beginning with the
letter “s”.
