怎樣才能用VB.NET的代碼來(lái)關(guān)閉一個(gè)在運(yùn)行的程序

軟糖來(lái)回答羅：通過(guò)System.Diagnostics命名空間下的Process類來(lái)關(guān)閉程序的進(jìn)程

Dim?進(jìn)程集合?=?Process.GetProcessesByName("進(jìn)程名稱")

For?Each?進(jìn)程?In?進(jìn)程集合

進(jìn)程.Kill()

'進(jìn)程.Close()?'或者使用關(guān)閉

Next

也可以先獲取所有進(jìn)程，再來(lái)判斷這些進(jìn)程的名稱ProcessName

Dim?獲取本地所有進(jìn)程?=?Process.GetProcesses()

For?Each?進(jìn)程?In?獲取本地所有進(jìn)程

If?進(jìn)程.ProcessName?=?"explorer.exe"?Then?進(jìn)程.Kill()

Next

如何在編的VB.NET程序使用時(shí)關(guān)閉電腦

有兩種方法，第一種是調(diào)用shutdown.exe

shell("shutdown.exe路徑 -s -t 0") '-t是延遲時(shí)間，0表示立刻關(guān)機(jī)

另一種就是使用API了，好像是ExitWindow，你可以去搜索一下其用法。
