C# example: List files in a directory using ListView

ListView can be used to implement a file manager.Here i simply specify a hint to list files of a directory.

for this, first drag and drop a ListView control to your form. Set it's view property to Details. In the column property add a new column and set its text to "Filename".

now, use this reference to your code

using System.IO;         //This should be added to your code if you want to do file operations.

now in the load event of the form write the below code

         try

            {
// Check if directory is present or not

                if ( Directory.Exists( @"C:\Users\Public\Pictures\Sample Pictures") )

                {

                    DirectoryInfo di = new DirectoryInfo(@"C:\Users\Public\Pictures\Sample Pictures");

// here if '@' is not used then we need to write "C:\\Users\\Public\\Pictures\\Sample Pictures"

                    FileInfo[] files = di.GetFiles();

                    foreach (FileInfo f in files)

                    {
//filename(without path) is added to listview1

                        listView1.Items.Add(f.Name);
// to add full path name then use 'FullName' property instead of 'Name' property

                    }

                }

                else

                    MessageBox.Show("Folder doesn't exist");

            }

            catch (Exception ex)

            {

                MessageBox.Show(ex.Message,"Error");

            }


The above code can be written simply as below

         try

            {
// Check if directory is present or not

           if ( Directory.Exists( @"C:\Users\Public\Pictures\Sample Pictures") )

           {                

                   

  foreach (FileInfo f in new DirectoryInfo(@"C:\Users\Public\Pictures\Sample Pictures").GetFiles())

                    {
//filename(without path) is added to listview1

                        listView1.Items.Add(f.Name);

                    }

                }

                else

                    MessageBox.Show("Folder doesn't exist");

            }

            catch (Exception ex)

            {

                MessageBox.Show(ex.Message,"Error");

            }
