Converting a URI path to a relative file system path in .NET

Question

How do I convert an absolute or relative URI path (e.g. /foo/bar.txt) to a (segmentwise) corresponding relative file system path (e.g. foo\\bar.txt

Answer 1

I figured out this way to produce a full absolute file system path from a relative or absolute URI and a base path.

With:

Uri basePathUri = new Uri(@"C:\abc\");

From a relative URI:

string filePath = new Uri(basePathUri, relativeUri).AbsolutePath;

From an absolute URI:

// baseUri is a URI used to derive a relative URI
Uri relativeUri = baseUri.MakeRelativeUri(absoluteUri);
string filePath = new Uri(basePathUri, relativeUri).AbsolutePath;
