帮助了解文件夹路径的大小

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。然而问题是，随着搜索深入到共享中，循环中的文件路径变量变得很大，抛出异常，因此无法继续。我发现一些东西说结合@"\\?\" 可以增加字符数，但我不知道如何正确附加它。如您所料，我的分享采用\\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);
        }
    }
}

尝试建议的答案后引发异常

Answer 1

你可以这样做：

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());
