This article mainly introduces "what is the method of C # Windows application". In daily operation, I believe that many people have doubts about what the method of C # Windows application is. The editor consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful for you to answer the doubt of "what is the method of C # Windows application?" Next, please follow the editor to study!

We use Visual Studio 2005 to create the sample program. First, create a blank project of the C # Windows application and name the solution and project GetLogicDrives. On the default Form1 form, we each place a ListView and a Button control, leaving the default name of the control unchanged, set the View property of ListView1 to Details, double-click the Columns property of ListView1, and add five columns for the details view, namely: disk letter, volume label, type, capacity and free space. Set the Text property of Button1 to Refresh to add a click event for the Button1

The code of the C # Windows application is as follows:

Private void button1_Click (object sender, EventArgs e) {listView1.Items.Clear (); SelectQuery selectQuery = new SelectQuery ("select * from win32_logicaldisk"); ManagementObjectSearcher searcher = new ManagementObjectSearcher (selectQuery); int item0; foreach (ManagementObject disk in searcher.Get ()) {/ / disk letter listView1.Items.Add (disk ["Name"]. ToString ()); / / Volume label try {listView1.Items.Add (disk ["VolumeName"]. ToString ()) } catch {listView1.Items[ I] .SubItems.Add ("device not ready");} / / Drive type string DriveType; try {DriveType = disk ["DriveType"]. ToString (); switch (DriveType) {case "0": listView1.Items.SubItems.Add ("unknown device"); break; case "1": listView1.Items[ I] .SubItems.Add ("not partitioned"); SubItems.Add ("not partitioned") Case "2": listView1.Items[ I] .SubItems.Add ("removable disk"); break; case "3": listView1.Items[ I] .SubItems.Add ("hard disk"); break; case "4": listView1.Items [I] .SubItems.Add ("network drive"); break; case "5": listView1.Items[ I] .SubItems.add ("CD-ROM"); break Case "6": listView1.Items[ I] .SubItems.Add ("memory disk"); break;}} catch {listView1.Items.Add ("unknown type");} / / capacity try {listView1.Items [I] .SubItems.Add (GetSizeUseUnit (disk ["Size"]. ToString ());} catch {listView1.Items [I] .SubItems.Add ("device not ready") } / / remaining space try {listView1.Items[ I] .SubItems.Add (GetSizeUseUnit (disk ["FreeSpace"]. ToString ());} catch {listView1.Items.SubItems.Add ("device not ready");} itemsAdd;} items.Add;} at this point, the study of "what is the method of C# Windows application" is over, hoping to solve everyone's doubts. The collocation of theory and practice can better help you learn, go and try it!
