C# 中的文件大小监控

我在系统与技术部门工作。管理团队并被赋予创建配额管理应用程序的任务，以尝试鼓励用户更好地管理资源，因为我们目前存在磁盘空间问题并且不强制执行硬配额。

目前，我正在使用下面的代码来浏览用户主空间中的所有文件，以检索他们正在使用的空间总量。从我所看到的情况来看，在 C# 中没有其他方法可以做到这一点，它的问题是它们的开销相当高，同时它会取消每个文件的大小然后创建总计。

try
{
    long dirSize = 0;
    FileInfo[] FI = new DirectoryInfo("I:\\").GetFiles("*.*", SearchOption.AllDirectories);
    foreach (FileInfo F1 in FI)
    {
        dirSize += F1.Length;
    }

    return dirSize;
}

因此，我正在寻找一种更快的方法来执行此操作，或者一种在使用 FileSystemWatcher 提供的选项时监视文件大小变化的快速方法。目前我唯一能想到的就是创建一个包含文件位置和每个文件大小的哈希表，因此当发生大小更改事件时，我可以将旧大小与新大小进行比较并更新总数。

任何建议将不胜感激。

I work in the Systems & admin team and have been given the task of creating a quota management application to try and encourage users to better manage there resources as we currently have issues with disc space and don't enforce hard quotas.

At the moment I'm using the code below to go through all the files in a users homespace to retrieve the overall amount of space they are using. As from what I've seen else where theres no other way to do this in C#, the issue with it is theirs quite a high overhead while it retireves the size of each file then creates a total.

try
{
    long dirSize = 0;
    FileInfo[] FI = new DirectoryInfo("I:\\").GetFiles("*.*", SearchOption.AllDirectories);
    foreach (FileInfo F1 in FI)
    {
        dirSize += F1.Length;
    }

    return dirSize;
}

So I'm looking for a quicker way to do this or a quick way to monitor changes in the size of files while using the options avaliable through FileSystemWatcher. At the moment the only thing I can think of is creating a hashtable containing the file location and size of each file, so when a size changed event occurs I can compare the old size against the new one and update the total.

Any suggestions would be greatly appreciated.
