ManagementScope Conn = new ManagementScope("＼＼＼＼" + txtWmiIpOrAddress.Text + "＼＼root＼＼cimv2", options);　处报错：ManagementException : Invalid parameter

[解决办法]
貌似是你斜线是半角的吧？？？
ManagementScope Conn = new ManagementScope("＼＼＼＼" + txtWmiIpOrAddress.Text + "＼＼root＼＼cimv2", options);

ManagementScope 类
===================》

 ManagementScope Conn = new ManagementScope("\\\\FullComputerName\\root\\cimv2");
 scope.Connect();

目测反斜杠是全角的，全角字符不是合法的路径字符，
