UserAppDataReigistry不會持續

我有以下類來堅持我的相機設置。UserAppDataReigistry不會持續

using System; 
using System.Drawing; 
using System.Windows.Forms; 
using DevExpress.XtraEditors.Camera;   

public class CameraDeviceHelper 
    { 
     public string DeviceMoniker; 
     public string DeviceName; 
     public int DeviceResolutionWidth; 
     public int DeviceResolutionHeight; 

     const string kDeviceName = "CameraDeviceName"; 
     const string kDeviceMoniker = "CameraDeviceMoniker"; 
     const string kDeviceResolutionWidth = "CameraDeviceResolutionWidth"; 
     const string kDeviceResolutionHeight = "CameraDeviceResolutionHeight"; 

     public bool SaveCameraDevice(CameraControl cc) 
     { 
      try 
      { 
       DeviceMoniker = cc.Device.DeviceMoniker; 
       DeviceName = cc.Device.Name; 
       DeviceResolutionWidth = cc.Device.Resolution.Width; 
       DeviceResolutionHeight = cc.Device.Resolution.Height; 

       Application.UserAppDataRegistry.SetValue(kDeviceName, DeviceName); 
       Application.UserAppDataRegistry.SetValue(kDeviceMoniker, DeviceMoniker); 
       Application.UserAppDataRegistry.SetValue(kDeviceResolutionWidth, DeviceResolutionWidth); 
       Application.UserAppDataRegistry.SetValue(kDeviceResolutionHeight, DeviceResolutionHeight); 

       return true; 
      } 
      catch (Exception) 
      { 
       return false; 

      } 

     } 
     public bool RestoreCameraDevice(CameraControl cc) 
     { 
      try 
      { 
       DeviceName = Application.UserAppDataRegistry.GetValue(kDeviceName, DeviceName).ToString(); 
       DeviceMoniker =Application.UserAppDataRegistry.GetValue(kDeviceMoniker, DeviceMoniker).ToString(); 
       DeviceResolutionWidth = (int) Application.UserAppDataRegistry.GetValue(kDeviceResolutionWidth, DeviceResolutionWidth); 
       DeviceResolutionHeight = (int)Application.UserAppDataRegistry.GetValue(kDeviceResolutionHeight, DeviceResolutionHeight); 

       var moniker = new DevExpress.Data.Camera.CameraDeviceInfo(DeviceMoniker, DeviceName); 
       cc.Device = new CameraDevice(moniker); 
       var sz = new Size(DeviceResolutionWidth,DeviceResolutionHeight); 
       cc.Device.Resolution = sz; 
       if (cc.Device.Resolution.Width != sz.Width) 
       { MessageBox.Show("Not set");} 

       cc.Start(); 

       return true; 
      } 
      catch (Exception) 
      { 
       return false; 

      } 

     } 
    } 
}

應用程序運行時的持續工作。但是，當我重新啓動應用程序時，設置會丟失。

我叫我的窗體的負荷的方法和FormClosed事件

private void Camera_Load(object sender, EventArgs e) 
    { 
     textEdit1.Text = PhotoCaption; 
     cameraDeviceHelper = new CameraDeviceHelper(); 
     try 
     { 
      cameraDeviceHelper.RestoreCameraDevice(cameraControl1); 

     } 
     catch (Exception) 
     { 
      // probably first time... so just dont complain 
      throw; 
     } 

    } 

    private void Camera_FormClosed(object sender, FormClosedEventArgs e) 
    { 
     cameraDeviceHelper.SaveCameraDevice(cameraControl1); 
    }

顯示所有相關代碼。例如。所有你稱之爲「SaveCameraDevice」和「RestoreCameraDevice」的地方。 –

你是否連載然後回到文件？看到這個鏈接https://msdn.microsoft.com/en-gb/library/ms973902.aspx –

看着http://geekswithblogs.net/whiletrue/archive/2009/01/11/save-configuration-settings-in -registry.aspx –

的解決方案是不是有一個*在每一個應用程序生成註冊表項將改變時間的AssemblyVersion 否則。
