是否可以从另一个 c# 控制台应用程序控制 WinForm?

问题描述

我是 2 天大的 .NET C# 编码员，试图从 ProjectB - C# 控制台应用程序控制 ProjectA - WinForm.

I'm 2 days old .NET C# coder trying to get control on ProjectA - WinForm from ProjectB - C# console app.

基本上，我使用 WatiN 在 ProjectA 中的 WebBrowser 控件中自动进行测试.

Basically I'm using WatiN to automate test within WebBrowser control in ProjectA.

当我运行执行 winformWithWebBrowserTest.exe 的 ProjectB 时，显示带有 webbrowser 的 winform.但是随后它无法访问form1.如何从 ProjectB 访问 webbrowser 控件???

When I run ProjectB which executes winformWithWebBrowserTest.exe, the winform with webbrowser shows up. But then it fails to access form1. How can I access the webbrowser control from ProjectB ???

错误:

System.Runtime.IteropServices.InvalidComObjectException
COM
object that has been separated from its underlying RCW cannot be used

ProjectA WinForm: (winformWithWebBrowserTest.exe)

namespace WindowsFormsApplication1
{
    public partial class Form1 : System.Windows.Forms.Form
    {
        public Form1()
        {
            InitializeComponent();
        }
    }//end class

}//end namespace

项目 B 控制台应用:(WatinConsoleExample.cs)

namespace ConsoleApplication1
{
    class WatinConsoleExample
    {
        [STAThread]
        static void Main(string[] args)
        {
            //run ProjectA exe
            System.Diagnostics.Process Proc = new System.Diagnostics.Process();
            Proc.StartInfo.FileName = "C:\\Users\\m-takayashiki\\Documents\\Visual Studio 2010\\Projects\\winformWithWebBrowserTest\\winformWithWebBrowserTest\\bin\\Release\\winformWithWebBrowserTest.exe";
            Proc.Start();


            WindowsFormsApplication1.Form1 form1 = new Form1();

            var t = new Thread(() =>
            {
                Settings.AutoStartDialogWatcher = false;
                //exception occurs below ..........
                var ie = new IE(form1.webBrowser1.ActiveXInstance);
                ie.GoTo("http://www.google.com");
                ie.TextField(Find.ByClass("lst")).TypeText("this is awesome!!");
                ie.Button(Find.ByName("btnG")).Click();
            });
            t.SetApartmentState(ApartmentState.STA);
            t.Start();

        }
    }
}

推荐答案

您不能这样做，因为两个进程都在各自的进程空间中运行您需要进行进程间通信，这对于 2 天大的人来说是不推荐的:)

You cannot do it , since both processes are running in their seperate process space & you need to go over interprocess communication which is not recommended for a 2 days old:).
