系统诊断过程开始查询 [英] System Diagnostics Process Start Query

问题描述

我的应用程序已经在后台编写定时的Excel工作表.我现在已经导出了Excel工作表，并希望从我的应用程序中将其打开.

因此使用了process.start

System.Diagnostics.Process.Start(FilePath);

问题是在打开文件后，控件没有返回到代码，并且我的打开文件对话框挂起.

因此，我必须关闭该应用程序并重新启动它.

请提出一个解决方案.

My application is already writing a timed excel sheet in the background. I have now exported and excel sheet and want to open it from my application.

so for it is used process.start

System.Diagnostics.Process.Start(FilePath);

Problem is after the file is being opened, control does not return to the code and my open file dialog box hangs.

Thus i have to close the application and restart it.

Please Suggest a solution.

推荐答案

谁在开发这种没有线程的东西?您应该从UI线程执行任何阻止调用，甚至不要执行任何耗时的操作.不幸的是，您没有与我们分享您使用哪种类型的应用程序或UI库，但是想法非常相似.

Who is developing such things without threading? You should do any blocking call from the UI thread, not even any time-consuming operations. Unfortunately, you did not share with us what type of application or UI library do you use, but the ideas are very similar.
