managementclassc#怎么获取USB储存设备，比如U盘/移动硬盘/硬盘盒（硬盘）/内存卡都获取出盘符

C#中创建ManagementClass为什么会函数计算超时？

问题解决办： 右键前程序集引用选择添加引用.NET选项卡选择System.Management点击确定即 虽程序写using System.Management:实际没添加.dll文件引用 者FF是CPU或者主板芯片坏,也可能是供电不足：

C# winform授权：获取cpu和硬盘的序列号，得到机器码，传给服务器端，从而生成注册码，使软件注册使用。问

首先在添加引用中选中System.Management 再在开始部门： using System.Management; using System.Management.Instrumentation; private void GetInfo() { string cpuInfo = "";//cpu序列号 ManagementClass cimobject = new ManagementClass("Win32_Processor"); ManagementObjectCollection moc = cimobject.GetInstances(); foreach(ManagementObject mo in moc) { cpuInfo = mo.Properties["ProcessorId"].Value.ToString(); Response.Write ("cpu序列号："+cpuInfo.ToString ()); } //获取硬盘ID String HDid; ManagementClass cimobject1 = new ManagementClass("Win32_DiskDrive"); ManagementObjectCollection moc1 = cimobject1.GetInstances(); foreach(ManagementObject mo in moc1) { HDid = (string)mo.Properties["Model"].Value; Response.Write ("硬盘序列号："+HDid.ToString ()); } //获取网卡硬件地址 ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration"); ManagementObjectCollection moc2 = mc.GetInstances(); foreach(ManagementObject mo in moc2) { if((bool)mo["IPEnabled"] == true) Response.Write("MAC address {0}"+mo["MacAddress"].ToString()); mo.Dispose(); } } 在添加引用中选中System.Management 再在开始部门： using System.Management; using System.Management.Instrumentation; private void GetInfo() { string cpuInfo = "";//cpu序列号 ManagementClass cimobject = new ManagementClass("Win32_Processor"); ManagementObjectCollection moc = cimobject.GetInstances(); foreach(ManagementObject mo in moc) { cpuInfo = mo.Properties["ProcessorId"].Value.ToString(); Response.Write ("cpu序列号："+cpuInfo.ToString ()); } //获取硬盘ID String HDid; ManagementClass cimobject1 = new ManagementClass("Win32_DiskDrive"); ManagementObjectCollection moc1 = cimobject1.GetInstances(); foreach(ManagementObject mo in moc1) { HDid = (string)mo.Properties["Model"].Value; Response.Write ("硬盘序列号："+HDid.ToString ()); } //获取网卡硬件地址 ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration"); ManagementObjectCollection moc2 = mc.GetInstances(); foreach(ManagementObject mo in moc2) { if((bool)mo["IPEnabled"] == true) Response.Write("MAC address {0}"+mo["MacAddress"].ToString()); mo.Dispose(); } } 有原始数据，生成注册码的部分，按算法处理一下就行，好象这种方法挻流行。

在WMI中，通过Win32_DiskDrive对象可以获取磁盘驱动器的相关信息： ManagementClass mc = new ManagementClass("Win32_DiskDrive"); ManagementObjectCollection moc = mc.GetInstances(); foreach (ManagementObject mo in moc) { propertyInfo = mo.Properties[PropertyName].Value.ToString(); }
