Question

我有以下函数用于标识启动特定进程的用户的用户名：

 Private Function GetProcessAssociatedUserID(ByVal processName As String) As String
    Dim user(1) As String

    Try
        Dim query As New SelectQuery(processName)
        Dim searcher As New System.Management.ManagementObjectSearcher(query)
        For Each process As ManagementObject In searcher.Get()
            process.InvokeMethod("GetOwner", CType(user, Object()))
        Next
    Catch ex As Exception

    End Try

    Return user(0)

End Function

然而，在ForEach启动的某个地方，我得到了这个＆＃34; ManagementException被抓住了：无效的课程＆＃34;异常抛入我的catch块。我已经通过调试但仍然无法解决问题。任何帮助将不胜感激。

你可以尝试这样做

Private Function GetProcessAssociatedUserID(ByVal processName As String) As String
    Dim query = "Select * from Win32_Process Where Name = """ + processName + """"
    Dim searcher = New ManagementObjectSearcher(query)
    Dim processList = searcher.Get()    
    For Each mObj As ManagementObject In processList
        Dim argList As String() = {String.Empty, String.Empty}
        Dim returnVal = Convert.ToInt32(mObj.InvokeMethod("GetOwner", argList))
        If returnVal = 0 Then
            Return argList(1) + "\\" + argList(0)
        End If
    Next
    Return ""
End Function

此代码段适用于.NET Framework 3.5及更高版本。有关详细信息，请参阅using-managementobjectsearcher-in-systemmanagement-is-getting-compiling-errors
