Question

我有一个方法，允许在word中打开word文档，并在完成之前等待单词退出。

如果单词尚未运行，则一切正常。

如果word正在运行，则该过程立即退出，因此我可以等待退出。

如果单词已经在运行，我可以等待文档关闭的任何想法吗？

这是在Windows 8.1

    public void ShowExternalReference(string externalRef, bool waitForCompletion)
    {
        if (externalRef.NotEmpty())
        {
            var pInfo = new ProcessStartInfo {FileName = externalRef};

            // Start the process.
            Process p = Process.Start(pInfo);

            if (waitForCompletion)
            {
                // Wait for the window to finish loading.
                p.WaitForInputIdle();

                // Wait for the process to end.
                p.WaitForExit();
            }
        }
    }

您可以获取当前正在运行的Word进程并附加到事件

我收到了一些信息here

以下是将文档附加到文档中并将其放入文档的示例...

希望这有帮助。

using Word = Microsoft.Office.Interop.Word;


namespace WindowsFormsApplication1
{

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }

    private void Form1_Load_1(object sender, EventArgs e)
    {
    }

    public void ShowExternalReference(string externalRef, bool waitForCompletion)
    {
        if (externalRef.Length > 0)
        {
            var pInfo = new ProcessStartInfo { FileName = externalRef };
            bool isrunning = false;
            Process [] pList = Process.GetProcesses();
            foreach(Process x in pList)
            {
                if( x.ProcessName.Contains("WINWORD"))
                {
                    isrunning = true;
                    Word.Application myWordApp =
                          System.Runtime.InteropServices.Marshal.GetActiveObject(
                          "Word.Application") as Word.Application;
                    if(myWordApp.ActiveDocument.FullName.Contains(externalRef))
                        // do something
                        myWordApp.ActiveDocument.Content.Text = " already open";
                }
            }
            if(!isrunning)
            {
                // Start the process.
                Process p = Process.Start(pInfo);

                if (waitForCompletion)
                {
                    // Wait for the window to finish loading.
                    p.WaitForInputIdle();

                    // Wait for the process to end.
                    p.WaitForExit();
                }
            }
        }
    }


    private void button1_Click(object sender, EventArgs e)
    {
        string myWordFile = @"C:\Temp\test.docx";
        ShowExternalReference(myWordFile, true);
    }


    private void listView1_ItemChecked(object sender, ItemCheckEventArgs e)
    {
        listView1.Items[e.Index].Group = listView1.Groups[e.NewValue == CheckState.Checked ? 0 : 1];
    }

Answer 2

Process[] pname = Process.GetProcessesByName("winword.exe");
if(pname.Length == 0)
{
   //not running..
}

你可以通过一个后台线程来循环它，也许是为了不断测试Word是否正在运行，并在事件没有时触发事件

使用Word运行的Process.Start无法等待退出
