    public int ID { get; set; }
}

...

You should provide an override of Object.Equals and Object.GetHashCode:

public override bool Equals(object obj) {
    Student other = obj as Student;
    if(other == null) {
        return false;
    }
    return (this.Name == other.Name) && (this.ID == other.ID);
}

public override int GetHashCode() {
    return 33 * Name.GetHashCode() + ID.GetHashCode();
}

As for checking if two collections are equal, use Enumerable.SequenceEqual:

// first and second are IEnumerable
Assert.IsTrue(first.SequenceEqual(second)); 

Note that you might need to use the overload that accepts an IEqualityComparer.
