Check to see if a list contains more than one specified value

Questions
1

Hi All,

I have a list called blogCategoriesList (which is of type string) that is populated with the value of each blog category as it loops through each page by checking the value defined in the category dropdown property. So if I had three blog posts on my site and the categories were defined as football, darts, darts then this is what the list would contain.

I am trying to do an if check that verifies whether

  • the list contains a value that is the same category as the
    currentpage
  • the list contains more than one entry that is the same as the
    category of the current page

Examples

blogCategoriesList = football, darts, darts

  • if I was on a page that had the category set as darts then the if
    test should pass because the list contains darts and it also has more
    than one entry for darts in the list.

blogCategoriesList = football, Computing, darts

  • if I was on a page that had the category set as darts then the if
    test would fail because the list contains darts but it doesn’t have
    more than one entry for darts in the list.

I have been trying to work with the following code that uses groupby but struggling to get this to work at the moment.

@if (blogCategoriesList.Contains(Model.Content.GetPropertyValue("category")) && blogCategoriesList.GroupBy(n => n.Equals(Model.Content.GetPropertyValue("category"))).Any(c => c.Count() > 1))

Any help would be great

Many thanks

Paul
