本文实例讲述了C#实现读取指定盘符硬盘序列号的方法。分享给大家供大家参考，具体如下：
using System;
using System.IO;
using System.Runtime.InteropServices;
using System.Text;
using Microsoft.Win32;
namespace Wjb.ReadOrWriteIniAndReg
{
/**/ ////// 读取指定盘符的硬盘序列号
///
public class HardDiskVal
{
[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
);
/**/ ///
/// 获得盘符为drvID的硬盘序列号，缺省为C
///
///
///
public string HDVal( 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();
}
public string HDVal()
{
const int MAX_FILENAME_LEN = 256;
int retVal = 0;
int a =0;
int b =0;
string str1 = null ;
string str2 = null ;
int i = GetVolumeInformation(
"c:\\" ,
str1,
MAX_FILENAME_LEN,
ref retVal,
a,
b,
str2,
MAX_FILENAME_LEN
);
return retVal.ToString();
}
}
希望本文所述对大家C#程序设计有所帮助。
