有人有一些关于如何使用主机名、用户名和密码从远程系统检索 Win32_ComputerSystem WMI 类的对象的示例 C# 代码吗?

连接:
try
{
rcOptions = new ConnectionOptions();
rcOptions.Authentication = AuthenticationLevel.Packet;
rcOptions.Impersonation = ImpersonationLevel.Impersonate;
rcOptions.EnablePrivileges = true;
rcOptions.Username = servername + @"\" + username;
rcOptions.Password = password;
mScope = new ManagementScope(String.Format(@"\\{0}\root\cimv2", servername), rcOptions);
mScope.Connect();
if (mScope.IsConnected == true) { MessageBox.Show("Connection Succeeded", "Alert"); } else { MessageBox.Show("Connection Failed", "Alert"); }
if (mScope.IsConnected == true) { lblConnectionStateWarning.Text = "Connected"; } else { lblConnectionStateWarning.Text = "Disconnected"; } //I have a label that displays connectionstate, you can leave that out
}
catch (Exception ex) { MessageBox.Show(ex.Message); }
使用方法获取查询,加载到字典并返回到列表视图
private void FindWMI(string servername, string classSelection, ConnectionOptions rcOptions, ListView listView)
{
try
{
var dct = new Dictionary<string, string>();
List<ListViewItem> itemsList = new List<ListViewItem>();
oQuery = new ObjectQuery("select * from " + classSelection);
moSearcher = new ManagementObjectSearcher(mScope, oQuery);
moCollection = moSearcher.Get();
Invoke(new MethodInvoker(() =>
{
listView.Items.Clear();
}));
foreach (ManagementObject mObject in moCollection)
{
if (mObject != null)
{
foreach (PropertyData propData in mObject.Properties)
{
if (propData.Value != null && propData.Value.ToString() != "" && propData.Name != null && propData.Name != "")
dct[propData.Name] = propData.Value.ToString();
//Don't forget this, when the result is an array, you want all the strings in that array..
if (propData.Value is Array) { dct[propData.Name] = ""; foreach (string stringArray in (string[])propData.Value) { dct[propData.Name] += stringArray + "\n"; } }
}
}
}
foreach (KeyValuePair<string, string> listItem in dct)
{
ListViewItem lstItem = new ListViewItem(listItem.Key);
lstItem.SubItems.Add(listItem.Value);
itemsList.Add(lstItem);
}
Invoke(new MethodInvoker(() =>
{
listView.Items.AddRange(itemsList.ToArray());
}));
}
catch (Exception) { }
}
