how to display files inside directory

Question

i am trying to get list of files inside the directory in this case "c:\dir\" (ofcourse i have files inside) and i wanted to display the name of those files in console program build in c#....

initially i did this....

static class Program
    {
        static void Main()
        {
            string[] filePaths = Directory.GetFiles(@"c:\dir\");
            Console.WriteLine();
            Console.Read();


        }
    }

how can i see the name of those files....... any help would be appreciated.....

thank you.

(further i would like to know if possible any idea on sending those file path towards dynamic html page.... any general concept how to do that...)

If by "file names" you mean literally just the names and not the full paths:

string[] filePaths = Directory.GetFiles(@"c:\dir");
for (int i = 0; i < filePaths.Length; ++i) {
    string path = filePaths[i];
    Console.WriteLine(System.IO.Path.GetFileName(path));
}

So if you wanted to display a message "Directory is empty..." or something like that would you use an if/else statement? If so what would the criteria for if be? I tried "if i == 0" as my if criteria but it's not working. – Matt P Jul 01 '14 at 19:38
@MattP: Sounds like you want to check `if (filePaths.Length == 0)` (outside the `for` loop)? – Dan Tao Jul 01 '14 at 20:11

Loop through the files and print them one at a time:

foreach(string folder in Directory.GetDirectories(@"C:\dir"))
{
    Console.WriteLine(folder);
}

foreach(string file in Directory.GetFiles(@"C:\dir"))
{
    Console.WriteLine(file);
}

but it doesnot shows me the folder names e.g i got 5 folder and 1 .jpeg it only displays .jpeg. – tike Jan 29 '10 at 20:12
Use Directory.GetDirectories to print all the folders as well. I edited the post to show this. – Aaron Jan 29 '10 at 20:14
GetFiles returns an array of type FileInfo , it should be foreach(FileInfo fi in Directory.GetFiles(@"C:\Dir")) { Console.WriteLine(file.Name);} – Ta01 Jan 29 '10 at 20:14
@tike: Then you want `GetFileSystemEntries` instead of `GetFiles`. – Dan Tao Jan 29 '10 at 20:16
@bnkdev: You're mistaken; `Directory.GetFiles` returns a string[]. The `DirectoryInfo.GetFiles` method returns a FileInfo[]. – Dan Tao Jan 29 '10 at 20:18

Send paths towards an HTML file? I'm not sure what you mean by this. Do you want to fill an HTML file with paths? Are you trying to host a web page that lists files on your local drive? – Aaron Jan 29 '10 at 20:29
actually this is basic web server development process.. i want to learn how to create a dynamic html page which could take path for files.... for example above filepaths. basically i want to create a html file which could give me link to that particular file which was displayed in my console application. – tike Jan 29 '10 at 20:33

Keep in mind that if there are many files in the folder you will have memory problems.
.Net 4.0 contains a fix: C# directory.getfiles memory help
