@inherits Custom.Hybrid.RazorTyped
@using ToSic.Razor.Blade

@{ var currentPageUrl = Link.To(parameters: MyPage.Parameters); }
<ol>
  <li>
    <a href='@Link.To()'>Link to current page <em>without</em>
    Parameters: @Link.To()</a>
  </li>
  <li>
    <a href='@currentPageUrl'>Link to current page preserving 
    parameters @currentPageUrl</a>
  </li>
</ol>

Because MyPage.Parameters / CmsContext.Page.Parameters follows the query string convention adding a new parameter isn't too difficult.
To add a new parameter you can use the .Add(key, value) method or add the parameters as string following the convention as for example &name=2sxc.

Current page URL with new parameter from string: https://2sxc.org/dnn-tutorials/en/razor/settings/home/tut/code-link-parameters-modify/name/2sxc

Current page URL with new parameter from .Add(...): https://2sxc.org/dnn-tutorials/en/razor/settings/home/tut/code-link-parameters-modify/name/2sxc

@inherits Custom.Hybrid.RazorTyped
@using ToSic.Razor.Blade

@{
  // Example using string
  var newParamsFromString = MyPage.Parameters + "&name=2sxc";

  // Page parameters using .Add(...) method
  var newParamsFromAdd = MyPage.Parameters.Add("name", "2sxc");
}

<p>Current page URL with new parameter from string: @Link.To(parameters: newParamsFromString)</p>
<p>Current page URL with new parameter from <code>.Add(...)</code>: @Link.To(parameters: newParamsFromAdd)</p>

To remove a parameter you can use the .Remove(key) method or modify the string containing parameters.

Current page URL with removed parameter: https://2sxc.org/dnn-tutorials/en/razor/settings/home/tut/code-link-parameters-modify

@inherits Custom.Hybrid.RazorTyped
@using ToSic.Razor.Blade

@{
  var currentParamsRemoved = MyPage.Parameters.Remove("basics320");
}
<!-- unimportant stuff, hidden -->
<p>Current page URL with removed parameter: @Link.To(parameters: currentParamsRemoved)</p>

To change a parameter you can use the .Set(key, value) method or modify the string containing parameters.

@inherits Custom.Hybrid.RazorTyped
@using ToSic.Razor.Blade

@{
  var currentParamsChanged = MyPage.Parameters.Set("basics320", "2sxc");
}
<!-- unimportant stuff, hidden -->
<p>Current page URL with changed parameter: @Link.To(parameters: currentParamsChanged)</p>
