Suppose that you want to list all BMP files under the 
f:\Pictures directory. You can write a code as shown in the 
code snippet given in Listing 3: 

Listing

DirectoryInfo dir = new DirectoryInfo(@"F:\WINNT");
FileInfo[] bmpfiles = dir.GetFiles("*.bmp);
Console.WriteLine("Total number of bmp files", 
bmpfiles.Length);
Foreach( FileInfo f in bmpfiles)
{
  Console.WriteLine("Name is : {0}", f.Name);
  Console.WriteLine("Length of the file is : {0}", 
f.Length);
  Console.WriteLine("Creation time is : {0}", 
f.CreationTime);
  Console.WriteLine("Attributes of the file are : {0}",
                    f.Attributes.ToString());
}
