识别网络路径存在的最快方法 [英] Fastest way to identify Network Path Exists

问题描述

在我的应用程序中，我需要搜索网络路径并根据文件夹的存在进行一些处理.让我们举个例子，我必须在网络上搜索路径，如果路径存在，我必须启用一些控件，否则我需要禁用这些控件.我尝试使用 DirectoryInfo 对象并获得正确的值:

In my application I need to search for a network path and do some processing based on the existence of the folder. Let us take an example, I have to search for a path on network and if path exists I have to enable some controls otherwise I need to disable the controls. I tried using DirectoryInfo object and getting the correct values:

    DirectoryInfo dirInfo = new DirectoryInfo(@"\ServerIPAddress\FolderName");

    if(dirInfo.Exists)
    {
            //do something
    }
    else
    {
           //do something else
    }

上述代码的问题是获取 Exists 属性需要花费超过 2 分钟的时间.

The problem with the above code is it is consuming more than 2 minutes for getting the Exists property.

有没有更快的方法来检查网络路径是否存在.

Is there any faster way to check for network path existence.

谢谢和问候，

推荐答案

通常只有在指定路径中不存在文件夹时，这才需要时间.您可以使用不同的线程来检查此处描述的文件夹的存在(以及代表):如何在 GetFileAttributes 中避免网络停顿?

Usually this would take time only if the folder does not exist in the specified path. You could use a different thread to check the existence of the folder as described here (along with delegates): How to avoid network stalls in GetFileAttributes?
