c# - Process.Start with Word 运行失败等待退出

Question

我有一个方法可以让一个word文档在word中打开，然后等待word退出后再完成。

如果 word 尚未运行，则一切正常。

如果 word 正在运行，进程会立即退出，所以我不能等待退出。

如果 word 已经在运行，我有什么想法可以等待文档关闭吗？

这是在 Windows 8.1 上

    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();
            }
        }
    }

可以获取当前运行的Word Process并附加到事件

我得到了一些信息 here

这是一个附加文本并将其放入文档的示例...

希望这对您有所帮助。

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];
    }
