来自 C# 进程类的无效操作异常 [英] Invalid Operation Exception from C# Process Class

问题描述

当我使用 VSTS 调试器查看 Process 类实例的属性时，许多属性都被标记为 InvalidOperationException.为什么?我做错了什么吗?

When I use VSTS debugger to see the properties of instance of class Process, many of the properties are marked with InvalidOperationException. Why? Am I doing anything wrong?

我正在使用 VSTS 2008 + C# + .Net 2.0 来开发控制台应用程序.

I am using VSTS 2008 + C# + .Net 2.0 to develop a console application.

这是我的代码:

System.Diagnostics.Process myProcess = new System.Diagnostics.Process();
myProcess.StartInfo.FileName = "IExplore.exe";
myProcess.StartInfo.Arguments = @"www.google.com";
myProcess.StartInfo.Verb = "runas";
myProcess.Start();

以及调试器的截图:

推荐答案

在拍摄调试器图片时，您是否真的开始了这个过程?这是我希望在调用 Start() 方法之前看到的屏幕截图.

Had you actually started the process when the debugger picture was taken? That's the screenshot I'd expect to see before the Start() method is called.

注意，常见的模式是创建一个ProcessStartInfo，填充它，然后调用静态的Process.Start(startInfo) 方法.这使得它在概念上更简单:在 Process 对象启动之前，您不会看到它.

Note that the common pattern is to create a ProcessStartInfo, populate it, and then call the static Process.Start(startInfo) method. That makes it conceptually simpler: you don't see the Process object until it's been started.
