帮助文件夹路径的大小

Question

我正在尝试编写一个应用程序来使用以下代码计算一组共享的大小。然而，问题在于，随着搜索深入到共享中，循环中的文件路径变量变得很大，引发异常并因此不能继续。我发现一些说合并@"\\?\"允许charachter计数增加，但我不知道如何正确地追加它。正如您所期望的，我的份额采用\\server\name的形式。

谢谢。

try 
{ 
    //Checks if the path is valid or not 
    if (!Directory.Exists(folder)) 
    { 
     return folderSize; 
    } 
    else 
    { 
     try 
     { 
      foreach (string filePath in Directory.GetFiles(folder)) 
      { 
       if (File.Exists(filePath)) 
       { 
        FileInfo finfo = new FileInfo(filePath); 
        folderSize += finfo.Length; 
       } 
      } 

      foreach (string dir in Directory.GetDirectories(folder)) 
       folderSize += GetDirectorySize(dir); 
     } 
     catch (NotSupportedException e) 
     { 
      Console.WriteLine("Unable to calculate folder size: {0}", e.Message); 
     } 
    } 
}

Answer 1

抛出后你可能只是做这样的事情：

DirectoryInfo di = new DirectoryInfo(rootFolder); 
foreach (FileInfo finfo in di.GetFiles("*.*", SearchOption.AllDirectories) 
{ 
    folderSize += finfo.Length; 
} 

Answer 2

试试这个：

string path = @"\\Server\Share"; 

System.IO.DirectoryInfo dInfo = new System.IO.DirectoryInfo(path); 
long totalSize = 0; 

foreach (FileInfo fInfo in dInfo.GetFiles("*", SearchOption.AllDirectories)) { 
    totalSize += fInfo.Length; 

} 

Console.Out.WriteLine(totalSize.ToString());
