估计只能用api了

[jinta2001]

WMI可以的

[huangjinyin]

在C#下能实现吗？用API？

[jinta2001]

using System;
using System.Management;
using System.Windows.Forms;

namespace WMISample
{
public class MyWMIQuery
{
public static void Main()
{
try
{
ManagementObjectSearcher searcher =
new ManagementObjectSearcher("root\\CIMV2",
"SELECT * FROM Win32_PrintJob");

foreach (ManagementObject queryObj in searcher.Get())
{
Console.WriteLine("-----------------------------------");
Console.WriteLine("Win32_PrintJob instance");
Console.WriteLine("-----------------------------------");
Console.WriteLine("Document: {0}", queryObj["Document"]);
}
}
catch (ManagementException e)
{
MessageBox.Show("An error occurred while querying for WMI data: " + e.Message);
}
}
}
}

如果是使用API来处理打印任务，光那些参数就会搞死人

WMI的MSDN那有呢，或技术指南的，入门级的
