Equivalent of Tuple (.NET 4) for .NET Framework 3.5

Question

Is there a class existing in .NET Framework 3.5 that would be equivalent to the .NET 4 Tuple?

I would like to use it in order to return several values from a method,

Answer 1

I'm using this in my pre-4 projects:

public class Tuple  
{ 
    public Tuple(T1 item1) 
    { 
        Item1 = item1; 
    }   

    public T1 Item1 { get; set; }  
} 

public class Tuple : Tuple  
{ 
    public Tuple(T1 item1, T2 item2) : base(item1) 
    { 
        Item2 = item2; 
    } 

    public T2 Item2 { get; set; }  
} 

public class Tuple : Tuple  
{ 
    public Tuple(T1 item1, T2 item2, T3 item3) : base(item1, item2) 
    { 
        Item3 = item3; 
    } 

    public T3 Item3 { get; set; }  
} 

public static class Tuple  
{ 
    public static Tuple Create(T1 item1) 
    { 
        return new Tuple(item1); 
    } 

    public static Tuple Create(T1 item1, T2 item2) 
    { 
        return new Tuple(item1, item2); 
    } 

    public static Tuple Create(T1 item1, T2 item2, T3 item3) 
    { 
        return new Tuple(item1, item2, item3); 
    }  
}
