我认为您必须更新您的代码，如下所示。

private void btnGetPrinters_Click(object sender, EventArgs e) 
{ 
    // Use the ObjectQuery to get the list of configured printers 
    var oquery = new System.Management.ObjectQuery("SELECT * FROM Win32_Printer"); 

    var mosearcher = new System.Management.ManagementObjectSearcher(oquery); 

    System.Management.ManagementObjectCollection moc = mosearcher.Get(); 

    foreach (ManagementObject mo in moc) 
    { 
     System.Management.PropertyDataCollection pdc = mo.Properties; 

     foreach (System.Management.PropertyData pd in pdc) 
     { 
      if ((bool)mo["Network"]) 
      { 
       cmbPrinters.Items.Add(mo[pd.Name]); 
      } 
     } 
    } 
}
