Question

我想通过vb.net使用完整文件路径终止应用程序，所以我正在使用此代码段

Public Sub forceCopy()
        Try
            'Dim strDatabasePath As String = My.Computer.FileSystem.CombinePath(Application.UserAppDataPath, "LIC.mdf")
            'Dim strdbLogPath As String = My.Computer.FileSystem.CombinePath(Application.UserAppDataPath, "LIC_log.ldf")
            Dim strDatabasePath As String = My.Computer.FileSystem.CombinePath(My.Application.Info.DirectoryPath, "LIC.mdf")
            Dim strdbLogPath As String = My.Computer.FileSystem.CombinePath(My.Application.Info.DirectoryPath, "LIC_log.ldf")
            Dim path As String = My.Computer.FileSystem.CombinePath(My.Application.Info.DirectoryPath, "LIC.mdf")
            Dim matchingProcesses = New List(Of Process)

            For Each process As Process In process.GetProcesses()
                For Each m As ProcessModule In process.Modules
                    If String.Compare(m.FileName, path, StringComparison.InvariantCultureIgnoreCase) = 0 Then
                        matchingProcesses.Add(process)
                        Exit For
                    End If
                Next
            Next

            For Each p As Process In matchingProcesses
                p.Kill()
            Next
            My.Computer.FileSystem.CopyFile(strDatabasePath, "c:\backup\LIC.mdf", True)

            My.Computer.FileSystem.CopyFile(strdbLogPath, "c:\backup\LIC_log.ldf", True)

            MessageBox.Show("Backup taken successfully")
        Catch ex As Exception
            MsgBox(ex.Message)
        End Try


    End Sub

我收到异常“访问被拒绝”。有什么想法？编辑：我在此行收到错误：For Each m As ProcessModule In process.Modules

Answer 1

您需要使用Try / Catch包装If String.Compare(m.FileName, ...)块。有几个假的和特权进程，其FileName属性是您无法访问的。

像这样杀死SQL Server是一个非常糟糕的想法。使用ServiceController类很好地问。您需要UAC elevation才能这样做。

Answer 2

只有提升的进程才能枚举您不拥有的进程加载的模块。
