  • Hard to say w/o seeing your code. Here is an example to consider.

    var dictionary = new Dictionary<string, string>()
    {
        {"Owner","Karen Payne"},
        { "VP", "Mary Payne" }
    };
    
    var key = "Owner";
    Console.WriteLine(dictionary
        .ContainsKey(key) ? dictionary[key] : $"{key} not found");
    
    key = "Owners";
    Console.WriteLine(dictionary
        .ContainsKey(key) ? dictionary[key] : $"{key} not found");
