C# Win32_帐户类异常行为

我正在做一个小小的计算机信息工具。现在我正在做用户帐户。我用可用的用户填充一个组合框

ManagementObjectSearcher mosAccounts = new ManagementObjectSearcher("SELECT * FROM Win32_Account");

        foreach (ManagementObject moUA in mosAccounts.Get())
        {
            comboBox4.Items.Add(moUA["Name"].ToString());
        }

然后我显示它们：

private void comboBox4_SelectedIndexChanged(object sender, EventArgs e)
    {
        ManagementObjectSearcher mosAccounts = new ManagementObjectSearcher("SELECT * FROM Win32_Account");

        foreach (ManagementObject moUA in mosAccounts.Get())
        {
            lblDescriptionUA.Text = "Description: " + moUA["Description"].ToString();

            if (moUA["Domain"] != null)
            {
                lblDomain.Text = "Domain: " + moUA["Domain"].ToString();
            }

            else
                lblDomain.Text = "Domain: Not Available";

            if (moUA["InstallDate"] != null)
            {
                lblInstallDateUA.Text = "Install Date: " + moUA["InstallDate"].ToString();
            }

            else
                lblInstallDateUA.Text = "Install Date: Not Available";

            lblLocalAccount.Text = "Local Account: " + moUA["LocalAccount"].ToString();

            if (moUA["SID"] != null)
            {
                lblSID.Text = "SID: " + moUA["SID"].ToString();
            }

            else
                lblSID.Text = "SID: Not Available";

            if (moUA["SIDType"] != null)
            {
                lblSIDType.Text = "SID Type: " + moUA["SIDType"];
            }

            else
                lblSIDType.Text = "SID Type: Not Available";

            if (moUA["Status"] != null)
            {
                lblStatusUA.Text = "Status: " + moUA["Status"].ToString();
            }

            else
                lblStatusUA.Text = "Status: Not Available";
        }
    }

但每次我从组合框中选择一个用户时，标签都会变得疯狂，显示如此多的信息，并切换它。就像他们在一行中显示所有用户的信息一样。我有什么遗漏吗

附加信息：我正在工作。有很多域用户。组合框显示了它们的全部内容。Mybe是因为所有的域用户。我做了一个选项，只显示本地用户，但同样的问题

是-因为这正是您的代码所说的：

// Every time you select a user...
private void comboBox4_SelectedIndexChanged(object sender, EventArgs e)
{
    // Find all the information about all users...
    ManagementObjectSearcher mosAccounts =
        new ManagementObjectSearcher("SELECT * FROM Win32_Account");

    // Iterate over all those users and display it
    foreach (ManagementObject moUA in mosAccounts.Get())
    {
        ...
    }
}

代码正按照您的要求执行。现在，为什么要连接这样的事件处理程序？想想当所选索引更改时，您实际想要实现什么。你真的只想找到一个选中的用户吗？如果是这样，您可能只需要更改在

ManagementObjectSearcher

中使用的查询，然后查找单个结果，而不是迭代所有结果
