怎么获取打印机和打印状态,还有其对应的打印文件的队列?

[lg314]

如题.就像系统提供的打印机状态查看,同时也可以删除打印队列的文档.有什么办法可以实现吗?

使用API EnumJobs

收藏了 。等待高手指点

using System.Management; 
string printerName = "HP";
string query = string.Format("SELECT * from Win32_Printer WHERE Name LIKE '%{0}%'", printerName);
ManagementObjectSearcher searcher = new ManagementObjectSearcher(query);
ManagementObjectCollection coll = searcher.Get();

foreach (ManagementObject printer in coll)
{
    foreach (PropertyData property in printer.Properties)
    {
        MessageBox.Show(string.Format("{0}: {1}", property.Name, property.Value));
    }
} 

记得Add reference, System.Mamagement这DLL
