I've seen a lot of articles and questions about how to be sure that Excel actually quits when you want it to and the process doesn't stay alive. Here is a knowledge Base article describing the problem and Microsoft's recommended solution. Essentially: 'close files 'Quit Excel xlApp.quit() 'Release and collect garbage System.Runtime.InteropServices.Marshal.FinalReleaseComObject(xl
我已经看到很多关于如何确保Excel实际上在您需要时退出并且该过程不会保持活跃状态的文章和问题。 以下是描述问题的知识库文章和Microsoft推荐的解决方案。 主要有： 'close files 'Quit Excel xlApp.quit() 'Release and collect garbage System.Runtime.InteropServices.Marshal.FinalReleaseComObject(xlApp) GC.Collect() GC.WaitForPendingFinalizers() 许多人不建议杀死这个过程; 请参阅如何正确清理Excel互操作
This is a follow on question to How to properly clean up excel interop objects in c#. The gyst is that using a chaining calls together (eg. ExcelObject.Foo.Bar() ) within the Excel namespace prevents garbage collection for COM objects. Instead, one should explicitly create a reference to each COM object used, and explicitly release them using Marhsal.ReleaseComObject(). Is the behaviour of n
这是如何正确清理c＃中的excel interop对象的问题。 gyst是在Excel命名空间内使用链接调用（例如，ExcelObject.Foo.Bar（））可以防止COM对象的垃圾收集。 相反，应该明确地创建对每个使用的COM对象的引用，并使用Marhsal.ReleaseComObject（）明确地释放它们。 仅在特定于Excel COM对象的链接调用后不释放COM对象的行为？ 无论何时使用COM对象，应用这种模式是否矫枉过正？ 出于两个原因，处理Office应用程序时处理发行
I am not able to get my EXCEL (32) process closed once I am done using it. As you can see in the code below, once ProcessRFAFData function finishes its execution, the EXCEL process doesn't get closed (I can still see EXCEL.EXE*32 in the task manager). For this reason, when SaveErrors starts its execution, I get the following exception: System.Runtime.InteropServices.COMException (0x800A0
一旦完成使用，我无法关闭EXCEL（32）进程。 正如你在下面的代码中看到的那样，一旦ProcessRFAFData函数完成它的执行，EXCEL进程就不会关闭（我仍然可以在任务管理器中看到EXCEL.EXE*32 ）。 由于这个原因，当SaveErrors开始执行时，我得到以下异常： System.Runtime.InteropServices.COMException (0x800A03EC): Microsoft Office Excel cannot open or save any more documents because there is not enough available
I want to set 50 button's click event to - private void buttonOnOff(object sender, EventArgs e).

在设计器中，我已经初始化鼠标向上事件，如下所示this.axImgEdit1.MouseUp + = new System.Windows.Forms.MouseEventHandler（this.axImgEdit1_MouseUpEvent）; 在后面的代码中，事件如下所示。 private void axImgEdit1_MouseUpEvent（object sender，MouseEventArgs e） 但在运行时它是抛出错误。 事件鼠标上移在此ActiveX控件上无效 aximageedit也有它自己的eventargs，但是如果我写它会抛出编译时错误，就像没有重载

我需要在用户控制中添加按钮。 当按钮被点击时，url应该被捕获并存储在会话中。 当我点击按钮时，服务器点击事件没有被调用。 我很困惑，为什么它没有被调用。 我在这里犯了什么错误吗？ 请建议。 我有以下代码： ASCX： <input type="submit" id="QuickViewbutton" value="Click to add this page to Quick View" runat="server" onserverclick="addQuickView" clientidmode="Static"/> ascx.cs

In these delegates: EventHandler public delegate void EventHandler(object sender, EventArgs e); FormClosingEventHandler public delegate void FormClosingEventHandler(object sender, FormClosingEventArgs e); FormClosingEventArgs is inherited from EventArgs . Why can't I bind an FormClosing event with an event handler from EventHandler delegate? I know that the event handler's si
在这些代表中： EventHandler public delegate void EventHandler（object sender，EventArgs e）; FormClosingEventHandler 公共委托无效FormClosingEventHandler（对象发件人，FormClosingEventArgs e）; FormClosingEventArgs从EventArgs继承。 为什么我无法将FormClosing事件与EventHandler委托的事件处理程序绑定？ 我知道事件处理程序的签名必须匹配它的委托，但为什么它不支持匹配的继承类型？ 嗯，这很有
When I create buttons in c#, it creates private void button?_click(object sender,EventArgs e) method as well. How do I call button1_click method from button2_click? Is it possible?
