确定SharePoint 2007中使用子文件夹的网站集和子网站的文件大小

Question

此程序用于遍历我的所有网络应用程序，深入到所有网站集和子网站并确定每个网站集和子网站的空间。一切工作正常，如果我一次手动询问1网站集，但如果我试图让它发生编程我不断收到算术溢出异常。是否有人可以查看我的代码并解释为什么只有在尝试所有Web应用程序时才会发生此异常，而不是在单个网站集被询问时发生？

下面是代码：

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Text; 
using Microsoft.SharePoint; 
using Microsoft.SharePoint.Administration; 

namespace SiteSize 
{ 
    class Program 
    { 
     static void Main(string[] args) 
     { 
      long siteCollectionSize = 0; 

      string baseUrl = "http://intranet"; 

      Console.WriteLine("Base Url: " + baseUrl + " (Change baseUrl to list sites starting with)"); 
      foreach (SPWebApplication mainSite in SPWebService.ContentService.WebApplications) 
      { 
       foreach (SPSite siteCollections in mainSite.Sites) 
       { 
        foreach (SPWeb web in siteCollections.AllWebs) 
        { 
         long webSize = GetSPFolderSize(web.RootFolder) + web.RecycleBin.Cast<SPRecycleBinItem>().Sum(r => r.Size); 

         if (web.Url.StartsWith(baseUrl)) 
         { 
          Console.WriteLine(string.Format("({0} {1}", web.Url, FormatSize(webSize))); 
          siteCollectionSize += webSize; 
         } 
        } 
       } 
      } 
      Console.WriteLine("Total Size: " + FormatSize(siteCollectionSize)); 
     } 



     public static long GetSPFolderSize(SPFolder folder) 
     { 
      long folderSize = 0; 
      foreach (SPFile file in folder.Files) 
       folderSize += file.TotalLength + file.Versions.Cast<SPFileVersion>().Sum(f => f.Size); 
      folderSize += folder.SubFolders.Cast<SPFolder>().Sum(sf => GetSPFolderSize(sf)); 
      return folderSize; 
     } 

     public static string FormatSize(long size) 
     { 

      if (size > Math.Pow(1024, 3)) 
       return (size/Math.Pow(1024, 3)).ToString("#,#.##") + " GB"; 

      else if (size > Math.Pow(1024, 2)) 

       return (size/Math.Pow(1024, 2)).ToString("#,#.##") + " MB"; 

      else if (size > 1024) 
       return (size/1024).ToString("#,#.##") + " KB"; 

      else 
       return size.ToString("#,#.##") + " Bytes"; 
     } 
    } 
} 

以下是错误：

Answer 1

版本属性Size是一个int。这是问题。

尝试......

folderSize += file.TotalLength + file.Versions.Cast<SPFileVersion>().Sum(f => (long)f.Size);
