Image 控件占用图片资源不释放的问题的解决方法：

ＸＡＭＬ：

<Image Name="_imgDisplay" Stretch="Fill" /><dxe:PopupImageEdit                        Name="popupImageEdit" MouseDoubleClick="popupImageEdit_MouseDoubleClick"                        VerticalAlignment="Center"                        Width="300" IsReadOnly="true"                        PopupMaxHeight="400"                        PopupMaxWidth="400"                        ShowMenu="{Binding Path=IsChecked, ElementName=chkShowMenu}"                         Stretch="{Binding Path=EditValue, ElementName=cmbStretch}"                        ShowLoadDialogOnClickMode="{Binding Path=EditValue, ElementName=cmbLoadDialogMode}" />

点击“Edit Image” 调用系统自带绘图工具进行修改

/// <summary>/// 对Ｉｍａｇｅ控件上的图片进行修改/// </summary>/// <param name="sender"></param>/// <param name="e"></param>private void ImgEdit_Click(object sender, RoutedEventArgs e){string filePath = string.Format("\"{0}\"", ImgPath);// 先释放独占资源ImgOld = null;GC.Collect();System.Diagnostics.ProcessStartInfo processStartInfo = new System.Diagnostics.ProcessStartInfo();processStartInfo.FileName = "mspaint.exe";// 调用系统自带的绘图工具画图（修改）processStartInfo.Arguments = filePath;Process process = System.Diagnostics.Process.Start(processStartInfo);process.EnableRaisingEvents = true;process.WaitForExit();//　重然加载图片LoadImage();}

保存图片正常

其余部分代码：

private String _imgPath = String.Empty;public String ImgPath{get{return _imgPath;}set{_imgPath = value;OnPropertyChanged("ImgPath");}}private void LoadImage(){ImgPath = @"C:\\Documents and Settings\\Administrator\\My Documents\\My Pictures\\A4T3S4B74T8E0001.jpg";ImgOld = new BitmapImage(new Uri(ImgPath, UriKind.Absolute));popupImageEdit.Source = ImgOld.Clone();_imgDisplay.Source = ImgOld.Clone();}BitmapImage ImgOld = null;
