二、使用DiskID32.dll获取硬件标识
using System;
using System.Collections.Generic;
using System.Text;
using System.Runtime.InteropServices;
using System.Reflection;
using System.Security;
using System.Security.Cryptography;
using System.IO;
namespace TestDemo
{
public class ComputerInfo
{
[DllImport("DiskID32.dll")]
public static extern long DiskID32(ref byte DiskModel, ref byte DiskID);
public static string GetDiskID()
{
byte[] DiskModel = new byte[31];
byte[] DiskID = new byte[31];
int i;
string Model = "";
string ID = "";
if (DiskID32(ref DiskModel[0], ref DiskID[0]) != 1)
{
for (i = 0; i < 31; i++)
{
if (Convert.ToChar(DiskID[i]) != Convert.ToChar(0))
{
ID = ID + Convert.ToChar(DiskID[i]);
}
}
ID = ID.Trim();
}
else
{
Console.WriteLine("获取硬盘序列号出错");
}
return ID;
}
}
}
三、使用ManagementClass类获取
private void GetCpuId()
{
ManagementClass mc = new ManagementClass("Win32_Processor");
ManagementObjectCollection moc = mc.GetInstances();
string strID = null;
foreach (ManagementObject mo in moc)
{
strID = mo.Properties["ProcessorId"].Value.ToString();
break;
}
textBox1.Text += "CPU ID:" + strID;
}
private void GetMotherBoardId()
{
ManagementClass mc = new ManagementClass("Win32_BaseBoard");
ManagementObjectCollection moc = mc.GetInstances();
string strID = null;
foreach (ManagementObject mo in moc)
{
strID = mo.Properties["SerialNumber"].Value.ToString();
break;
}
textBox2.Text += "主板 ID:" + strID;
}
private void GetHardDiskId()
{
ManagementClass mc = new ManagementClass("Win32_PhysicalMedia");
//网上有提到，用Win32_DiskDrive，但是用Win32_DiskDrive获得的硬盘信息中并不包含SerialNumber属性。
ManagementObjectCollection moc = mc.GetInstances();
string strID = null;
foreach (ManagementObject mo in moc)
{
strID = mo.Properties["SerialNumber"].Value.ToString();
break;
}
textBox3.Text += "硬盘 ID:" + strID;
}
private void GetBiosId()
{
ManagementClass mc = new ManagementClass("Win32_BIOS");
ManagementObjectCollection moc = mc.GetInstances();
string strID = null;
foreach (ManagementObject mo in moc)
{
strID = mo.Properties["SerialNumber"].Value.ToString();
break;
}
textBox4.Text += "BIOS ID:" + strID;
}
private void GetMacAddressId()
{
ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration");
ManagementObjectCollection moc = mc.GetInstances();
string strMac = null;
foreach (ManagementObject mo in moc)
{
if ((bool)mo["IPEnabled"] == true)
{
strMac = mo["MacAddress"].ToString();
break;
}
}
textBox5.Text += "Mac Address:" + strMac;
}
private void GetAllProcessor()
{
ManagementClass mc = new ManagementClass("Win32_Processor");
ManagementObjectCollection moc = mc.GetInstances();
foreach (ManagementObject mo in moc)
{
richTextBox1.Text += "\r\n============CUP信息＝＝＝＝＝＝＝＝＝＝＝";
foreach (PropertyData pd in mo.Properties)
{
richTextBox1.Text += "\r\n" + pd.Name + "\t";
if (pd.Value != null)
{
richTextBox1.Text += pd.Value.ToString();
}
}
richTextBox1.Text += "\r\n\r\n============＝＝＝＝＝＝＝＝＝＝＝";
}
}
