Hey Kim,

What about

@inherits umbraco.MacroEngines.DynamicNodeContext

@inheritsUmbraco.Web.Mvc.UmbracoTemplatePage

@{
    Layout="SW_Master.cshtml";
        
    string tagToFind =Request.QueryString["tag"];
    var locations =Model.Content.AncestorOrSelf().DescendantsOrSelf().Where("tags != \"\"");

 if(tagToFind !=null){
        foreach(var node in locations){

                string[] tags =@node.tags.ToString().Split(',');
                
                if(tags.Contains(tagToFind)){@node.Url}
                
        }   
 }    
else{<p>No tag!</p>} 
} 

Hi Rich,

Thank you, but still the same error.

Could it be something else coursing the error? I'am not very found of this line:

 var locations = Model.Content.AncestorOrSelf().DescendantsOrSelf().Where("tags != \"\"");

Best regards
Kim 

Hey Kim,

I'd comment out some lines until you find the error, or open in Visual Studio which should give you some visual clues

Hi Rich,

Thank you again! I have found the line that's makes the error!

@{
   string tagToFind = Request.QueryString["tag"];
   var locations = Model.Content.AncestorOrSelf().DescendantsOrSelf().Where("tags != \"\"");
}


@if(tagToFind != null) {

        foreach (var node in locations){

        @* ------------------  This line is my problem: --------------------- *@
                string[] tags = @node.tags.ToString().Split(',');

                if (tags.Contains(tagToFind)) {
                        @node.Url
                }

        }       
}else {
        <p>No tag!</p>
}  

As Kim above says :)

It's a breaking change in v6 :-) http://issues.umbraco.org/issue/U4-1143#comment=67-4333

Great! 

Thank you all for your help!

Working code:

@{
   string tagToFind = Request.QueryString["tag"];
   var locations = Model.AncestorOrSelf().DescendantsOrSelf().Where("tags != \"\"");
}


@if(tagToFind != null) {

        foreach (var node in locations){

                string[] tags = node.tags.ToString().Split(',');

                if (tags.Contains(tagToFind)) {
                        @node.Url
                }

        }       
}else {
        <p>No tag!</p>
}

Best regards
