Use of Uri IsWellFormedUriString when Uri TryCreate works perfectly

Question

I am using code:

Uri.TryCreate(sURL, UriKind.Absolute, out URI)

which works fine.

Do I need to call Uri.IsWellFormedUriString(sURL, UriKind.Absolute) ? I mean I want to know what is the use of Uri.IsWellFormedUriString when Uri.TryCreate works perfectly?

Answer 1

Uri.IsWellFormedUriString calls TryCreate internally as well as calling Uri.IsWellFormedOriginalString so the results may differ from simply calling TryCreate.

From ILSpy

public static bool IsWellFormedUriString(string uriString, UriKind uriKind)
{
    Uri uri;
    return Uri.TryCreate(uriString, uriKind, out uri) && uri.IsWellFormedOriginalString();
}

From MSDN

[Uri.IsWellFormedOriginalString] indicates whether the string used to construct this Uri was well-formed and is not required to be further escaped.
