c# type to handle relative and absolute URI's and local file paths
提问by BCS
I have a use cases where I will be dealing with both local file paths (e.g. c:\foo\bar.txt) and URI's (e.g. http://somehost.com/fiz/baz). I also will be dealing with both relative and absolute paths so I need functionality like Path.Combineand friends.
我有一个用例，我将同时处理本地文件路径（例如c:\foo\bar.txt）和 URI（例如http://somehost.com/fiz/baz）。我还将处理相对路径和绝对路径，因此我需要像Path.Combine和朋友一样的功能。
Is there an existing C# type I should use?The Uri typemight work but at a passing glance, it seems to be URI only.
我应该使用现有的 C# 类型吗？该URI类型可能会奏效，但在路过一目了然，它似乎只是URI。

Using the Uri class, it seems to be working. It turns any file path to the `file:///..." syntax in the Uri. It handles any URI as expected, and it has capacity to deal with relative URIs. It depends on what else you are trying to do with that path.
使用 Uri 类，它似乎有效。它将任何文件路径转换为 Uri 中的 `file:///..." 语法。它按预期处理任何 URI，并且它具有处理相对 URI 的能力。这取决于您还想做什么那条路。
(Updated to show the use of relative Uri's):
（更新以显示相对 Uri 的使用）：
string fileName = @"c:\temp\myfile.bmp";
string relativeFile = @".\woohoo\temp.bmp";
string addressName = @"http://www.google.com/blahblah.html";
Uri uriFile = new Uri(fileName);
Uri uriRelative = new Uri(uriFile, relativeFile);
Uri uriAddress = new Uri(addressName);
Console.WriteLine(uriFile.ToString());
Console.WriteLine(uriRelative.ToString());
Console.WriteLine(uriAddress.ToString());
Gives me this output:
给我这个输出：
file:///c:/temp/myfile.bmp
file:///c:/temp/woohoo/temp.bmp
http://www.google.com/blahblah.html
