Can I use LINQ to check if objects in a list have a unique ID?
<p>say I have a list containing objects like this one:</p>

<pre><code>public class Person
{
    private string _name; 
    private string _id;
    private int _age;

    public Person 
    {
    }

    // Accessors
}

public class ManipulatePerson
{
    Person person = new Person();
    List&lt;Person&gt; personList = new List&lt;Person&gt;;

    // Assign values

    private void PopulateList();
    {
        // Loop 
        personList.Add(person);

        // Check if every Person has a unique ID
    }
}
</code></pre>

<p>and I wanted to check that each Person had a unique ID. I would like to return a boolean true/false depending on whether or not the IDs are unique. Is this something I can achieve with LINQ?</p>
