I am looking to retrieve the relative part of the current Blazor page URL.
For example if I am currently on https://www.mywebsite.com/someoverview, I wish to retrieve /someoverview.
It's not Blazor specific, we have the Uri class:
var uri = new Uri(@"https://www.mywebsite.com/someoverview");
var relativePath = uri.LocalPath; // or .PathAndQuery
or for the current Blazor page:
@inject NavigationManager Navigator
<a href="@Navigator.ToBaseRelativePath(Navigator.Uri)">here</a>
but do note that ToBaseRelativePath() does not include a leading /
, it is different from LocalPath. You can mix & match.
