c#

    var setsA = new List<SetA> {
        new SetA { SsnA = "3450734507", name = "setA"},
        new SetA { SsnA = "6833467788", name = "setA"},
        new SetA { SsnA = "5452347787", name = "setA"},
        new SetA { SsnA = "9345345345", name = "setA"},
    };

    var setsB = new List<SetB> {
        new SetB { SsnB = "5452347787" ,name = "setB"},
        new SetB { SsnB = "9345345345", name = "setB"},
    };

when i use this linq:

var Set =
                from seta in setsA
                join setb in setsB
                 on seta.SsnA
                    equals setb.SsnB
                select new { 
                    SSN = seta.SsnA,
                    NAME = setb.name
                };

i get this value:

{ SSN = "5452347787", NAME = "setB" }
{ SSN = "9345345345", NAME = "setB" }

but i would want to have SET which combines these two and the result would be:

{ SSN = "3450734507", NAME = "setA" }
{ SSN = "6833467788", NAME = "setA" }
{ SSN = "5452347787", NAME = "setB" }
{ SSN = "9345345345", NAME = "setB" }

This would be a result set that would tell me with the name NAME property which set it was taken from, if SSN was found in SetA and SetB it would have property NAME = "setB"

could someone help me with this?
