Check if a uTaxonomy property contains a string
I have a node with a uTaxonomy property. When accessing my property I get this: "System.Collections.Generic.List`1[ASP.Taxonomy]".

When looping the Generic.List I get all the names of the taxonomies:
```
foreach(var item in employee.departments){
    @item
}
```
How can I, in this foreach, check if the list contains for example "accounting"?

I have tried using employee.departments.Contains("accounting"), but I am getting this:
```
The best overloaded method match for 'System.Collections.Generic.List<ASP.Taxonomy>.Contains(ASP.Taxonomy)' has some invalid arguments
```

Hi Søren,

I think you have a problem, because when you are trying to call the Contains method, departments property is a dynamic type.

Try this:
```
@(((string)item.ToString()).Contains("accounting"))
```
I hope I understood you correctly.

I'll add another method that will return (true/false), if the required value is in the collection or not

Hi Vitaly

Thanks! I got it to work by doing this:

    bool showEmployee = false;
    foreach(var item in employee.departments){
        if((((string)item.ToString().ToLower()).Contains(kategori))){
            showEmployee = true;
        }
    }
    if(showEmployee){
        <div>Employee data</div>
    }

It's not pretty, but it solves my problem :-)

Hi Søren,

You can try to add below method in TaxonomyExtensions class in Taxonomy.cs which is located in the App_Code folder.

public static bool HasValue(this IEnumerable<Taxonomy> values, string value)
    {
        return values.Any(x => x.Item.Name == value);
    }

How to use:

@{ var taxonomy = Model.Content.GetPropertyValue<List<Taxonomy>>("yourPropertyName"); }

@if(taxonomy.HasValue("accounting")){ // first code } else { // second code }

Best regards, Vitaly
