vb.net怎么结束进程?Imports System
Imports System.Management
Module Module1
Public Sub Main()
Dim service As ManagementObject = New ManagementObject( "win32_service=""winmgmt""")
Dim options As InvokeMethodOptions = New InvokeMethodOptions
options.Timeout = New TimeSpan(0, 0, 0 , 5)
Dim outParams As ManagementBaseObject = service.InvokeMethod("StopService" , Nothing, options)
Console.WriteLine("状态vb.net结束:"outParams("Returnvalue"))

vb.net中如何结束一个线程vb.net中如何结束一个线程
一般而言,如果您想终止一个线程,您可以使用System.Threading.Thread类的Abort方法. 例如:
Dim worker As ThreadStart = New ThreadStart(AddressOf workerthreadmethod)
Dim t As Thread = New Thread(worker)
t.Start()
MessageBox.Show("Wait for a while for the thread to start.")
MessageBox.Show(t.ThreadState.ToString())
t.Abort()
MessageBox.Show(t.ThreadState.ToString())
t.Join()
MessageBox.Show(t.ThreadState.ToString())
当然,在调用Abort方法后,线程并不是立刻终止,要等线程的所有finally快中的代码完成后才会完全终止. 所以在主线程中可以用Join方法来同步,当线程还未完全终止时,t.Join()将处于等待,直到t线程完全结束后再继续执行后面的语句 。
Abort方法是会导致线程跳出一个异常错误的,你需要在代码中捕获该异常 。下面是一个比较完整的VB.NET线程例子:
Imports System
Imports System.Threading
Public Class MyTestApp
Public Shared Sub Main()
Dim t As New Thread(New ThreadStart(AddressOf MyThreadMethod))
'Start the thread
t.Start()
MsgBox("Are you ready to kill the thread?")
'Kill the child thread and this will cause the thread raise an exception
t.Abort()
' Wait for the thread to exit
t.Join()
MsgBox("The secondary thread has terminated.")
【vb.net结束 vb结束运行】End Sub
Shared Sub MyThreadMethod()
Dim i As Integer
Try
Do While True
Thread.CurrentThread.Sleep(1000)
Console.WriteLine("This is the secondary thread running.")
Loop
Catch e As ThreadAbortException
MsgBox("This thread is going to be terminated by the Abort method in the Main function")
End Try
End Sub
End Class
Thread.Abort()方法用来永久销毁一个线程,而且将抛出ThreadAbortException异常 。使终结的线程可以捕获到异常但是很难控制恢复,仅有的办法是调用Thread.ResetAbort()来取消刚才的调用,而且只有当这个异常是由于被调用线程引起的异常 。因此,A线程可以正确的使用Thread.Abort()方法作用于B线程,但是B线程却不能调用Thread.ResetAbort()来取消Thread.Abort()操作 。
vb.net 怎么结束进程好像不难吧?
我放进了Button1的Click事件里 。
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
On Error GoTo Errmessages'在做系统操作时加排错标签是个好习惯
Dim TargetName As String = "ibmdict" '存储进程名为文本型,注:进程名不加扩展名
Dim TargetKill() As Process = Process.GetProcessesByName(TargetName) '从进程名获取进程
Dim TargetPath As String'存储进程路径为文本型
If TargetKill.Length1 Then'判断进程名的数量 , 如果同名进程数量在2个以上 , 用For循环关闭进程 。
For i = 0 To TargetKill.Length - 1
TargetPath = TargetKill(i).MainModule.FileName
TargetKill(i).Kill()
Next
ElseIf TargetKill.Length = 0 Then'判断进程名的数量,没有发现进程直接弹窗 。不需要的 , 可直接删掉该If子句
MsgBox("没有发现进程!")
Exit Sub
ElseIf TargetKill.Length = 1 Then'判断进程名的数量,如果只有一个,就不用For循环
