Uri.AbsoluteUri vs Uri.OriginalString

I recently found out about the odd behavior of Uri.ToString() (namely, it decrypts some characters and is therefore primarily suitable for displaying). I am trying to resolve between AbsoluteUri and OriginalString as a "go-to" to convert a Uri object to a string (for example, as a razor).

So far, the only difference I have found between the two is that AbsoluteUri will not work for relative uris (for example, new Uri("foo", UriKind.Relative).AbsoluteUri ). This seems like a point in favor of OriginalString . However, I am worried about the word “original,” because it suggests that some things might not be encoded or shielded correctly.

Can anyone confirm the difference between these two properties (except for the one difference I found)?

Normalization is a good reason to use AbsoluteUri over OriginalString :

 new Uri("http://foo.bar/var/../gar").AbsoluteUri // http://foo.bar/gar new Uri("http://foo.bar/var/../gar").OriginalString // http://foo.bar/var/../gar

I always use OriginalString since I ran into several problems with AbsoluteUri . Namely:

AbsoluteUri behaves differently in .NET 4.0 vs .NET 4.5 ( see )

.NET Framework 4.0

 var uri = new Uri("http://www.example.com/test%2F1"); Console.WriteLine(uri.OriginalString); // http://www.example.com/test%2F1 Console.WriteLine(uri.AbsoluteUri); // http://www.example.com/test/1 <-- WRONG

.NET Framework 4.5

 var uri = new Uri("http://www.example.com/test%2F1"); Console.WriteLine(uri.OriginalString); // http://www.example.com/test%2F1 Console.WriteLine(uri.AbsoluteUri); // http://www.example.com/test%2F1

AbsoluteUri does not support relative URIs

 var uri = new Uri("/test.aspx?v=hello world", UriKind.Relative); Console.WriteLine(uri.OriginalString); // /test.aspx?v=hello world Console.WriteLine(uri.AbsoluteUri); // InvalidOperationException: This operation is not supported for a relative URI.

AbsoluteUri does unwanted shielding

 var uri = new Uri("http://www.example.com/test.aspx?v=hello world"); Console.WriteLine(uri.OriginalString); // http://www.example.com/test.aspx?v=hello world Console.WriteLine(uri.AbsoluteUri); // http://www.example.com/test.aspx?v=hello%20world <-- WRONG
