如何使用Vb.NET或C#终止进程?
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,那么我必须终止winword.exe进程并继续执行我的代码 是否有人使用vb.net或c#直接编写了终止进程的代码?您将要使用该方法。您可以使用 这里已经发布了一些示例,但我发现非.exe版本工作得更好,所以类似于:如何使用Vb.NET或C#终止进程?,c#,vb.net,process,kill,C#,Vb.net,Process,Kill,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,那么我必须终止winword.exe进程并继续执行我的代码 是否有人使用vb.net或c#直接编写了终止进程的代码?您将要使用该方法。您可以使用 这里已经发布了一些示例,但我发现非.exe版本工作得更好,所以类似于: foreach ( Process p in System.Diagnostics.Process.GetProcessesByName("winword") ) { try {
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
,这表明该进程是远程的。下面是一个简单的示例,说明如何终止所有Word进程
Process[] procs = Process.GetProcessesByName("winword");
foreach (Process proc in procs)
proc.Kill();
类似这样的方法会奏效:
foreach ( Process process in Process.GetProcessesByName( "winword" ) )
{
process.Kill();
process.WaitForExit();
}
完全终止Word进程是可能的(请参阅其他一些答复),但绝对是粗鲁和危险的:如果用户在打开的文档中有重要的未保存更改,该怎么办?更不用说这会留下陈旧的临时文件 这可能是您在这方面所能做到的(VB.NET):
这将有序地关闭所有打开的Word窗口(如果适用,提示用户保存其工作)。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(最好通过弹出“请关闭所有Word实例,否则我们无法继续”对话框…您可以绕过安全问题,通过简单地检查Word进程是否正在运行,创建一个更礼貌的应用程序,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,只有当你的应用程序有GUI时,你才能这样做。更好的做法是,更安全、更礼貌地检测进程是否正在运行,并告诉用户手动关闭它。当然,如果进程消失,您也可以添加超时并终止进程…请参见下面的示例
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;
