c# - 如何使用 Vb.NET 或 C# 终止进程？

Question

我有一个场景，我必须检查用户是否已经打开了 Microsoft Word。如果他有，那么我必须杀死 winword.exe 进程并继续执行我的代码。

有没有人有任何使用 vb.net 或 c# 杀死进程的直接代码？

Answer 1

您需要使用System.Diagnostics.Process.Kill方法。您可以使用 System.Diagnostics.Proccess.GetProcessesByName获取所需的过程。

示例已在此处发布，但我发现非 .exe 版本效果更好，因此类似于：

foreach ( Process p in System.Diagnostics.Process.GetProcessesByName("winword") )
{
    try
    {
        p.Kill();
        p.WaitForExit(); // possibly with a timeout
    }
    catch ( Win32Exception winException )
    {
        // process was terminating or can't be terminated - deal with it
    }
    catch ( InvalidOperationException invalidException )
    {
        // process has already exited - might be able to let this one go
     }
}

您可能不必处理NotSupportedException，这表明该过程是远程的。

Answer 2

完全终止 Word 进程是可能的（参见其他一些回复），但完全粗鲁和危险：如果用户在打开的文档中有重要的未保存更改怎么办？更不用说这将留下的陈旧的临时文件......

这可能是您在这方面所能做到的（VB.NET）：

    Dim proc = Process.GetProcessesByName("winword")
    For i As Integer = 0 To proc.Count - 1
        proc(i).CloseMainWindow()
    Next i

这将有序地关闭所有打开的 Word 窗口（如果适用，提示用户保存他/她的工作）。当然，在这种情况下，用户始终可以单击“取消”，因此您也应该能够处理这种情况（最好通过“请关闭所有 Word 实例，否则我们无法继续”对话框... )

Answer 3

这是一个简单的示例，说明如何杀死所有文字进程。

Process[] procs = Process.GetProcessesByName("winword");

foreach (Process proc in procs)
    proc.Kill();

Answer 4

您可以绕过安全问题，创建一个更礼貌的应用程序，只需检查 Word 进程是否正在运行，并要求用户关闭它，然后单击应用程序中的“继续”按钮。这是许多安装人员采用的方法。

private bool isWordRunning() 
{
    return System.Diagnostics.Process.GetProcessesByName("winword").Length > 0;
}

当然，只有当您的应用程序有 GUI 时，您才能这样做

    public bool FindAndKillProcess(string name)
    {
        //here we're going to get a list of all running processes on
        //the computer
        foreach (Process clsProcess in Process.GetProcesses()) {
            //now we're going to see if any of the running processes
            //match the currently running processes by using the StartsWith Method,
            //this prevents us from incluing the .EXE for the process we're looking for.
            //. Be sure to not
            //add the .exe to the name you provide, i.e: NOTEPAD,
            //not NOTEPAD.EXE or false is always returned even if
            //notepad is running
            if (clsProcess.ProcessName.StartsWith(name))
            {
                //since we found the proccess we now need to use the
                //Kill Method to kill the process. Remember, if you have
                //the process running more than once, say IE open 4
                //times the loop thr way it is now will close all 4,
                //if you want it to just close the first one it finds
                //then add a return; after the Kill
                try 
                {
                    clsProcess.Kill();
                }
                catch
                {
                    return false;
                }
                //process killed, return true
                return true;
            }
        }
        //process not found, return false
        return false;
    }

Answer 6

在我的托盘应用程序中，我需要清理 Excel 和 Word 互操作。所以这个简单的方法一般会杀死进程。

这使用通用异常处理程序，但可以轻松拆分为多个异常，如其他答案中所述。如果我的日志记录产生很多误报（即不能杀死已经杀死的），我可能会这样做。但到目前为止如此指导（工作笑话）。

/// <summary>
/// Kills Processes By Name
/// </summary>
/// <param name="names">List of Process Names</param>
private void killProcesses(List<string> names)
{
    var processes = new List<Process>();
    foreach (var name in names)
        processes.AddRange(Process.GetProcessesByName(name).ToList());
    foreach (Process p in processes)
    {
        try
        {
            p.Kill();
            p.WaitForExit();
        }
        catch (Exception ex)
        {
            // Logging
            RunProcess.insertFeedback("Clean Processes Failed", ex);
        }
    }
}

这就是我当时的称呼：

killProcesses((new List<string>() { "winword", "excel" }));

Answer 7

像这样的东西会起作用：

foreach ( Process process in Process.GetProcessesByName( "winword" ) )
{
    process.Kill();
    process.WaitForExit();
}

Answer 8

检测进程是否正在运行并告诉用户手动关闭它是更好的做法，更安全和更有礼貌。当然，如果它们消失了，您也可以添加超时并终止进程...

Answer 9

我打开了一个 Word 文件，2。现在我通过 vb.net 运行时以编程方式打开另一个 word 文件。3.我想通过编程方式单独杀死第二个进程。4.不要杀死第一个进程

请看下面的例子
