c# - 从 MS-Word ApplicationClass 获取 PID？

Question

考虑这段代码:

using Microsoft.Office.Interop.Word;

ApplicationClass _application = new ApplicationClass();

我能否从 _application 启动的 Winword.exe 进程中获取 PID？

我需要 PID，因为文件已损坏，我无法退出 ApplicationClass，即使使用以下代码也是如此:

_application.Quit(ref saveFile, ref missing, ref missing);
System.Runtime.InteropServices.Marshal.ReleaseComObject(_application);
GC.Collect();
GC.WaitForPendingFinalizers();

我不能搜索winword.exe进程杀掉，因为我会有好几个，不知道杀哪个。如果我能为每个 ApplicationClass 获得一个 PID，我就可以杀死正确的 winword.exe 进程，它给我带来了退出的麻烦。

这是如何做到的。

//Set the AppId
string AppId = ""+DateTime.Now.Ticks(); //A random title

//Create an identity for the app

this.oWordApp = new Microsoft.Office.Interop.Word.ApplicationClass();
this.oWordApp.Application.Caption = AppId;
this.oWordApp.Application.Visible = true;

while (GetProcessIdByWindowTitle(AppId) == Int32.MaxValue) //Loop till u get
{
    Thread.Sleep(5);
}

///Get the pid by for word application
this.WordPid = GetProcessIdByWindowTitle(AppId);

///You canh hide the application afterward            
this.oWordApp.Application.Visible = false;

/// <summary>
/// Returns the name of that process given by that title
/// </summary>
/// <param name="AppId">Int32MaxValue returned if it cant be found.</param>
/// <returns></returns>
public static int GetProcessIdByWindowTitle(string AppId)
{
   Process[] P_CESSES = Process.GetProcesses();
   for (int p_count = 0; p_count < P_CESSES.Length; p_count++)
   {
        if (P_CESSES[p_count].MainWindowTitle.Equals(AppId))
        {
                    return P_CESSES[p_count].Id;
        }
   }

    return Int32.MaxValue;
}
