如何在整个系统中检查文件的给定路径是否存在 [英] how to check given path for file is exist or not in entire system

问题描述

大家好，



我有一些路径，比如programfiles\Test\test.xml。



我需要检查给定路径存在哪个驱动器。



例如，如果给定路径存在于C驱动器中，那么我需要返回C盘。



如何实现，C＃中是否有任何功能可以实现这一点。

Hi All,

I have some path like "programfiles\Test\test.xml".

I need to check in which drive the given path exists.

for example if the given the path exists in "C" drive then i need to return C drive .

How to achieve,Is there any functionality in C# through which we can achieve this.

推荐答案

不 - 你必须手动完成，依次检查每个驱动器。

No - you would have to do it manually, by checking each drive in turn.

DriveInfo[] drives = DriveInfo.GetDrives();

将列出所有可用的，并且drives [n] .Name属性将为您提供C：\部分，以便您可以使用Path.Combine形成一个完整的测试路径。

Will list all those available to you, and the drives[n].Name property will give you the "C:\" part so you can use Path.Combine to form a complete path for testing.
