幫助文件夾路徑的大小

Question

我正在嘗試編寫一個應用程序來使用以下代碼計算一組共享的大小。然而，問題在於，隨着搜索深入到共享中，循環中的文件路徑變量變得很大，引發異常並因此不能繼續。我發現一些說合並@"\\?\"允許charachter計數增加，但我不知道如何正確地追加它。正如您所期望的，我的份額採用\\server\name的形式。

謝謝。

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

拋出後你可能只是做這樣的事情：

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

Answer 2

試試這個：

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());
