C# accessing folder/files thru webservice

How can I have a webservice read/browse a folder content ?

For instance this type of code:

    FolderBrowserDialog folderBrowser;
    folderBrowser = new System.Windows.Forms.FolderBrowserDialog();

    folderBrowser.Description = "...";
    folderBrowser.ShowNewFolderButton = false;
    folderBrowser.RootFolder = Environment.SpecialFolder.MyComputer;

When I build the solution I get this error...

The type or namespace name 'FolderBrowserDialog' could not be found (are you missing a using directive or an assembly reference?)

I know it doesn't make a lot of sense trying to use a dialog in a webservice but how else can I do it?

My webservice receives a string and then I want to browse for files that contain that string in a folder.

Use a StreamReader to read a text file:

StreamReader reader = File.OpenText(filename);

string contents = reader.ReadToEnd();

reader.Close();

To list files in a folder:

 DirectoryInfo di = new DirectoryInfo(fullPathToFolder);
 FileInfo[] fileList = di.GetFiles("*.aspx");

 foreach(FileInfo fi in fileList)
 {
     // do something with fi.Name
 }

Have a look at the System.IO.Directory.GetFiles() method. Displaying the FolderBrowser dialog can naturally only be used with thick client interactive WinForms apps.

You'll need to use System.IO namespace to navigate into your filesystem; as you noted, doesn't make sense trying to display a dialog on a webservice call.
