问题 The problem When I try to save a file over ~1.5 MiB with EPPlus ExcelPackage.Save() throws a System.IO.IsolatedStorage.IsolatedStorageException . The explanation I'm creating a SSIS package with Visual Studio 2008 9.0.30729.4462 QFE and .NET Framework 3.5 SP1 to export the content of a SQL Server 2008 SP2 10.0.4311.0 64 bit table through the EPPlus 2.9.0.1 library.

问题 I'm trying to modify a combo box on my WinForms application, and I'm getting some strange behavior. I'm trying two methods: Here is the method I need to invoke: private void modifyCombo(ClassInfoHolder oldClass, ClassInfoHolder newClass) { this.monitoredComboBox.Items[monitoredComboBox.Items.IndexOf(oldClass)] = newClass; } I'm trying two different ways to invoke this method from the GUI thread. This one works: delegate void modifyComboCollection(ClassInfoHolder oldClass, ClassInfoHolder

问题 I've built a WPF Control which displays an Image. Now I would like to change that image at a very fast rate. I've build an ImageContainer class which holds the image and has a ChangedEventHandler which updates the Image in my control when changed. The code which is executed looks like this: videoImageThread = new Thread( new ThreadStart( delegate() { this.VideoCapture.Dispatcher.Invoke( System.Windows.Threading.DispatcherPriority.Normal, new Action( delegate() { videoImage.Source =

log4Net issues with NUnit (Tried v2.5.7, 2.5.2, 2.4.8, 2.4.7)

问题 I'm getting an error (see bottom of post) when running NUnit against a production code assembly. The production code assembly has a reference to a third party framework that uses log4net internally (Specifically, this is SimplyAccounting's SDK). The version of log4net that it uses is 1.2.9.0. Outside of this third party framework which we use via the public api from the dll files, log4net is not part of our production code. While troubleshooting, I eliminated the reference to the production

How to rethrow the inner exception of a TargetInvocationException without losing the stack trace

由 南笙酒味 提交于 2019-11-27 20:34:38
I have many methods which are calling using Delegate.DynamicInvoke . Some of these methods make database calls and I would like to have the ability to catch a SqlException and not catch the TargetInvocationException and hunt through its inners to find what's actually gone wrong. I was using this method to rethrow but it clears the stack trace: try { return myDelegate.DynamicInvoke(args); } catch(TargetInvocationException ex) { Func<TargetInvocationException, Exception> getInner = null; getInner = delegate(TargetInvocationException e) { if (e.InnerException is TargetInvocationException) return

Why is TargetInvocationException treated as uncaught by the IDE?

问题 I have some code that is using reflection to pull property values from an object. In some cases the properties may throw exceptions, because they have null references, etc. object result; try { result = propertyInfo.GetValue(target, null); } catch (TargetInvocationException ex) { result = ex.InnerException.Message; } catch (Exception ex) { result = ex.Message; } Ultimately the code works correctly, however when I am running under the debugger: When the property throws an exception, the IDE
