How to serialize System.Uri?

[JohanLarsson]

<Uri AbsoluteUri="https://gitter.im/GuOrg/Gu.Xml" />

Why not <Uri>https://gitter.im/GuOrg/Gu.Xml</Uri>?

[JohanLarsson]

Can we figure out relative/absolute in all cases when deserializing then?

[jnm2]

@JohanLarsson <Uri Relative="true">...</Uri> for the less common case?

I did think Uri could roundtrip through a string losslessly. Do you have tests with counterexamples?

[JohanLarsson]

Nope no unit tests, I don't use uri much so don't know it well. Hence the issue.

Looks like UriKind would need to be serialized: https://docs.microsoft.com/dotnet/api/system.uri.-ctor#System_Uri__ctor_System_String_System_UriKind_
It would be nice if the most common case was the shortest.

[JohanLarsson]

<Uri AbsoluteUri="https://gitter.im/GuOrg/Gu.Xml" />
<Uri RelativeUri="GuOrg/Gu.Xml" />

Are pretty short no?
But I agree that <Uri>https://gitter.im/GuOrg/Gu.Xml</Uri> feels most natural.

[jnm2]

I am pretty sure absolute is the most common, so my mind jumps to making that the default:

<Uri AbsoluteUri="https://gitter.im/GuOrg/Gu.Xml" />
<Uri>https://gitter.im/GuOrg/Gu.Xml</Uri>

<Uri Relative="true">GuOrg/Gu.Xml</Uri>

...but yes, all options presented so far are pretty short.

We also want new Uri("https://gitter.im/GuOrg/Gu.Xml", UriKind.Relative) to roundtrip. Not the business of a serialization library to fix bugs.
