C#在Linux下获取文件夹信息（所在磁盘总大小，使用空间，已用空间，使用率）

1.第一种使用shell命令实现：

 1 private DiskInfo LinuxGetFolderDiskInfo(string path)
 2         {
 3             DiskInfo disk = new DiskInfo();
 4             if (string.IsNullOrEmpty(path))
 5             {
 6                 return disk;
 7             }
 8             if (!path.StartsWith("/"))
 9             {
10                 path = "/" + path;
11             }
12 
13             string shellPathLine = string.Format("cd {0}", path);
14             string printLine = " awk '{print $2,$3,$4,$5}'";
15             string shellLine = string.Format("df -k {0} |", path) + printLine;
16             logger.Debug(string.Format("执行命令:{0}", shellLine));
17 
18             Process p = new Process();
19             p.StartInfo.FileName = "sh";
20             p.StartInfo.UseShellExecute = false;
21             p.StartInfo.RedirectStandardInput = true;
22             p.StartInfo.RedirectStandardOutput = true;
23             p.StartInfo.RedirectStandardError = true;
24             p.StartInfo.CreateNoWindow = true;
25             p.Start();
26             p.StandardInput.WriteLine(shellPathLine);
27             p.StandardInput.WriteLine(shellLine);
28             p.StandardInput.WriteLine("exit");
29 
30             string strResult = p.StandardOutput.ReadToEnd();
31             logger.Debug(string.Format("输出结果：{0}", strResult));
32             string[] arr = strResult.Split('\n');
33             if (arr.Length==0)
34             {
35                 return disk;
36             }
37             string[] resultArray = arr[1].TrimStart().TrimEnd().Split(' ');
38             if (resultArray==null || resultArray.Length == 0)
39             {
40                 return disk;
41             }
42 
43             disk.TotalSize = Convert.ToInt32(resultArray[0]);
44             disk.UsedSize = Convert.ToInt32(resultArray[1]);
45             disk.AvailableSize = Convert.ToInt32(resultArray[2]);
46             disk.Use = resultArray[3];
47             logger.Debug(string.Format("Linux获取目录：{0},总大小:{1},已用:{2},未用:{3},使用率:{4}", path, disk.TotalSize, disk.UsedSize, disk.AvailableSize, disk.Use));
48 
49             return disk;
50         }

2.第二种使用statvfs()函数实现：（需要下载Mono.Posix.dll，引用using Mono.Unix.Native;）

 1 public DiskInfo LinuxGetFolderDiskInfo(string path)
 2         {
 3             DiskInfo disk = new DiskInfo();
 4             try
 5             {
 6                 if (string.IsNullOrEmpty(path))
 7                 {
 8                     return disk;
 9                 }
10                 if (!path.StartsWith("/"))
11                 {
12                     path = "/" + path;
13                 }
14 
15                 Statvfs stavfs;
16                 Syscall.statvfs(path, out stavfs);
17                 disk.TotalSize = (long)(stavfs.f_blocks * stavfs.f_bsize);
18                 disk.AvailableSize = (long)(stavfs.f_bavail * stavfs.f_bsize);
19                 disk.UsedSize = (long)(stavfs.f_bfree * stavfs.f_bsize);
20 
21                 logger.Debug(string.Format("Linux获取目录：{0},总大小:{1},已用:{2},未用:{3}", path, disk.TotalSize, disk.UsedSize, disk.AvailableSize));
22                 return disk;
23             }
24             catch (Exception ex)
25             {
26                 logger.Error(ex);
27                 return disk;
28             }
29         }

 1 public class DiskInfo
 2     {
 3         public long TotalSize { get; set; }
 4 
 5         public long UsedSize { get; set; }
 6 
 7         public long AvailableSize { get; set; }
 8 
 9         public string Use { get; set; }
10     }
