第一种方法:
通过WMI来读取硬盘的ID.代码如下:
1 public string DiskDrive
2 {//硬盘厂商
3 get
4 {
5 string strDiskDrive;
6 ManagementObjectSearcher opSearch;
7 ManagementObjectCollection mocSystem;
8 strDiskDrive="";
9 try
10 {
11 opSearch = new ManagementObjectSearcher("SELECT * FROM Win32_DiskDrive");
12 mocSystem=opSearch.Get();
13 foreach( ManagementObject opInfo in mocSystem)
14 {
15 strDiskDrive+= opInfo["PNPDeviceID"].ToString().Trim() ;
16 }
17 }
18 catch
19 {
20 //TO DO：添加异常处理
21 }
22 return strDiskDrive;
23 }
24 }
2 {//硬盘厂商
3 get
4 {
5 string strDiskDrive;
6 ManagementObjectSearcher opSearch;
7 ManagementObjectCollection mocSystem;
8 strDiskDrive="";
9 try
10 {
11 opSearch = new ManagementObjectSearcher("SELECT * FROM Win32_DiskDrive");
12 mocSystem=opSearch.Get();
13 foreach( ManagementObject opInfo in mocSystem)
14 {
15 strDiskDrive+= opInfo["PNPDeviceID"].ToString().Trim() ;
16 }
17 }
18 catch
19 {
20 //TO DO：添加异常处理
21 }
22 return strDiskDrive;
23 }
24 }
第二种方法:
通过windowsAPI方法调用硬盘的ID.代码如下:
