c#键入以处理相对和绝对URI以及本地文件路径

使用Uri类,它似乎可以正常工作。它将任何文件路径转换为`file:///...Uri中的语法。它按预期处理任何Uri,并具有处理相对Uri的能力。这取决于您试图对该路径执行的其他操作。

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());

给我这个输出:

file:///c:/temp/myfile.bmp  
file:///c:/temp/woohoo/temp.bmp  
http://www.google.com/blahblah.html
