Solution 1

Use System.IO.Directory.GetFiles. See http://msdn.microsoft.com/en-us/library/system.io.directory.aspx[^].

It might help you,

C#

public static Int32 HowManyFiles(string folderName)
{
    return Directory.Exists(folderName) ? Directory.GetFiles(folderName).Count() : 0;
}
public static Int32 HowManyImageFiles(string folderName)
{
    //Need to update the list according your situation.
    IList myList = new List<string>() { ".jpeg", ".jpg", ".gif", ".bmp" };
    return Directory.Exists(folderName) ? Directory.GetFiles(folderName).Where(item => myList.Contains(Path.GetExtension(item))).Select(item => item).Count() : 0;
}

usage:

C#

var result = HowManyFiles(@"C:\temp");
var resultWithImage = HowManyImageFiles(@"C:\temp");

:)
