如何根据驱动名判断该驱动是否安装

先添加对System.Management的引用 using System.Management;
...
SelectQuery selectQuery = new SelectQuery("select * from win32_logicaldisk");
ManagementObjectSearcher searcher = new ManagementObjectSearcher(selectQuery);
int i = 0;
foreach (ManagementObject disk in searcher.Get())
{
//获取驱动器盘符
this.listBox1.Items.Add(disk["Name"].ToString());
}
