List layers in directory .Net ArcObjects or plain .Net -- C# preferably

Question

Any code samples to list arcgis layer files from a directory so they can be looped over?

Answer 1

Using a windows form, button, and listbox you could use this:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
 Try
 ' make a reference to a directory
 Dim di As New IO.DirectoryInfo("c:\temp")
 Dim diar1 As IO.FileInfo() = di.GetFiles("*.lyr*")
 Dim dra As IO.FileInfo
 'list the names of all files in the specified directory
 For Each dra In diar1
 ListBox1.Items.Add(dra.Name)
 Next
 Catch ex As Exception
 MessageBox.Show("Error " & ex.ToString)
 End Try
 End Sub

Answer 2

This should be easy to convert to C#, it is still .NET. Make sure to mark what artwork posted as the answer if it gives you the expected results.

try
{
 DirectoryInfo di = new DirectoryInfo(@"c:\temp");
 FileInfo diar1 = new di.GetFiles("*.lyr*");
 foreach(FileInfo dra in diar1)
 {
 ListBox1.Items.Add(dra.Name);
 }
}
catch(Exception ex)
{
 //do something with exception
}

The following function goes through a directory, gets a list of all the XML files, sorts the list by name, then writes the filenames of the XML files out to a text file. It does a little more than you need, but the principal is there of looping through the directory and doing something with the files - just another way to go about it.

public static void make_enerdeq_filelist(Constants c)
// Create Enerdeq_Filelist.txt to feed our ETL job
{
 // Kill Enerdeq_Filelist.txt if it exists
 if (File.Exists(c.infaServer + c.fileList))
 {
 File.Delete(c.infaServer + c.fileList);
 }
 // Sort files by name-alpha, INFA wants sorted input
 DirectoryInfo dir = new DirectoryInfo(c.infaServer);
 StreamWriter sw = File.CreateText(c.infaServer + c.fileList);
 string[] xml_files = Directory.GetFiles(c.infaServer);
 IComparer comp = new FileComparer(FileComparer.CompareBy.Name);
 Array.Sort(xml_files, comp);
 foreach (string xml_file in xml_files)
 {
 FileInfo fi = new FileInfo(xml_file);
 string file_name = fi.Name;
 if (file_name.EndsWith(".xml")) // XML files only
 {
 sw.WriteLine(file_name);
 sw.Flush();
 }
 }
 sw.Close();
}
