ManagementObjectSearcher选择网络打印机？

我使用 :

ManagementObjectSearcher searcher = new 
    ManagementObjectSearcher("root\\CIMV2", "SELECT * FROM Win32_Printer");

来获取打印机，但它找到本地打印机。可以通过ip选择网络打印机吗？

将“网络”传递给 ManagementObjectCollection 中每个项目的对象索引器。如果打印机是网络打印机，它将返回 true。同样，您可以传递“本地”来确定打印机是否是本地的。

var searcher = new ManagementObjectSearcher("root\\CIMV2", "SELECT * FROM Win32_Printer");
var results = searcher.Get();

IList<ManagementBaseObject> printers = new List<ManagementBaseObject>();

foreach (var printer in results) {
    if ((bool)printer["Network"]) {
        printers.Add(printer);
    }
}

Pass "Network" to the object indexer of each item in your ManagementObjectCollection. If the printer is a network printer it will return true. Likewise you can pass "Local" to determine if the printer is local.

var searcher = new ManagementObjectSearcher("root\\CIMV2", "SELECT * FROM Win32_Printer");
var results = searcher.Get();

IList<ManagementBaseObject> printers = new List<ManagementBaseObject>();

foreach (var printer in results) {
    if ((bool)printer["Network"]) {
        printers.Add(printer);
    }
}
