C#另外一种方法获取硬盘序列号

string GetDiskID()
        {
            try
            {
                //获取硬盘ID 
                String HDid = "";
                ManagementClass mc = new ManagementClass("Win32_DiskDrive");
                ManagementObjectCollection moc = mc.GetInstances();
                foreach (ManagementObject mo in moc)
                {
                    HDid = (string)mo.Properties["Model"].Value;
                }
                moc = null;
                mc = null;
                return HDid;
            }
            catch
            {
                return "unknow";
            }
            finally
            {
            }

        }

获取固有磁盘序列号：

 

ManagementClass命名空间是System.Management

以上代码用于获取C盘的序列号,而不是硬盘的固有序号.

获取硬盘的固有序号:

using System;
using System.Runtime.InteropServices;

namespace ArLi.CommonPrj {

#region how use this?
/*
string sVol = getvol.GetVolOf("C");
*/
#endregion

public class getvol{

[DllImport("kernel32.dll")]
private static extern int GetVolumeInformation(
string lpRootPathName,
string lpVolumeNameBuffer,
int nVolumeNameSize,
ref int lpVolumeSerialNumber,
int lpMaximumComponentLength,
int lpFileSystemFlags,
string lpFileSystemNameBuffer,
int nFileSystemNameSize
);

public static string GetVolOf(string drvID){
const int MAX_FILENAME_LEN = 256;
int retVal = 0;
int a =0;
int b =0;
string str1 = null;
string str2 = null;

int i = GetVolumeInformation(
drvID + @":\",
str1,
MAX_FILENAME_LEN,
ref retVal,
a,
b,
str2,
MAX_FILENAME_LEN
);

return retVal.ToString("x");
}
}
}
