我有一个场景需要检查用户是否已经打开了Microsoft Word。如果是,我需要杀死winword.exe进程并继续执行我的代码。
有没有人有用VB.NET或C#杀死进程的简单代码?
您需要使用System.Diagnostics.Process.Kill方法。您可以使用System.Diagnostics.Proccess.GetProcessesByName获取所需的进程。
已经在此处发布了示例,但我发现非.exe版本效果更好,因此类似以下内容:
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
}
}
你可能不需要处理NotSupportedException
,这表示该进程是远程的。
完全杀死Word进程是可能的(请参见其他回复),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?更不用说这将留下过时的临时文件了...
在这方面,这可能是你能做的最远的地方(VB.NET):
Dim proc = Process.GetProcessesByName("winword")
For i As Integer = 0 To proc.Count - 1
proc(i).CloseMainWindow()
Next i
这将按顺序关闭所有打开的Word窗口(如适用,提示用户保存其工作)。当然,在这种情况下,用户总是可以点击“取消”,因此您应该能够处理这种情况(最好通过弹出一个“请关闭所有Word实例,否则我们无法继续”的对话框...)
这里有一个简单的示例,可以说明如何终止所有的Word进程。
Process[] procs = Process.GetProcessesByName("winword");
foreach (Process proc in procs)
proc.Kill();
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;
}
您可以绕过安全问题,通过检查Word进程是否正在运行,并要求用户关闭它,然后在您的应用程序中单击“继续”按钮来创建一个更加礼貌的应用程序。这是许多安装程序采用的方法。
private bool isWordRunning()
{
return System.Diagnostics.Process.GetProcessesByName("winword").Length > 0;
}
/// <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);
}
}
}
killProcesses((new List<string>() { "winword", "excel" }));
CloseMainWindow
。我只希望他们有一天开始废弃像这样有害的API,这显然是内核级别的,任何用户空间应用程序都不应该有这种可能性。 - specializt类似这样的代码可以正常工作:
foreach ( Process process in Process.GetProcessesByName( "winword" ) )
{
process.Kill();
process.WaitForExit();
}
最好的做法是检测进程是否正在运行,并告诉用户手动关闭它,这样更安全、更礼貌。当然,您也可以添加超时并在用户离开后终止进程...
我打开了一个Word文件, 2. 现在我通过vb.net程序运行时以编程方式打开另一个Word文件。 3. 我想要单独通过编程方式终止第二个进程。 4. 不要终止第一个进程。
