c# - 访问被拒绝。 (来自 HRESULT : 0x80070005 (E_ACCESSDENIED) 的异常

Question

代码:

ManagementObjectSearcher searcher = new ManagementObjectSearcher(scope, query);
ManagementObjectCollection queryCollection = searcher.Get();

上面的代码抛出以下异常请帮助..我在一些文章中读到这个错误是由于 WMI 损坏而抛出的？是这种情况吗？我必须重建 WMI 还是有任何替代方法？或更好的解决方案

错误:

Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED)

System.Runtime.InteropServices.Marshal.ThrowExceptionForHRInternal(Int32 errorCode, IntPtr errorInfo) at System.Runtime.InteropServices.Marshal.ThrowExceptionForHR(Int32 errorCode) at System.Management.ManagementScope.InitializeGuts(Object o) at System.Management.ManagementScope.Initialize() at System.Management.ManagementScope.Connect() at WebApplication3.lanusers.Button1_Click1(Object sender, EventArgs e) in C:\Users\user\documents\visual studio 2010\Projects\WebApplication3\WebApplication3\lanusers.aspx.cs:line 120 IpAddress192.168.1.55HostNamenkn-PC

Answer 1

错误代码0x80070005与WMI权限有关。

0x8007xxx : Errors originating in the core operating system. WMI may return this type of error because of an external failure, for example, DCOM security failure.

为了修复此错误，您必须在客户端和服务器计算机中设置适当的权限。试试这些链接
