Comparing two list objects C#

Hi,
I have a requirement to compare two lists and figure out the differences in it.
Say, I have List<obj> objSt and List<tempobj> objTempSt, both Obj and tempObj has same definition that is something like
class Obj
{
int client_id;
string str;
decimal d;
datetime dt;
datetime curr_dt;
decimal rd;
string name;
}

class tempObj
{
int client_id;
string str;
decimal d;
datetime dt;
datetime curr_dt;
decimal rd;
string name;
}

here is the sample data for both the lists

Obj
-----
Client_id    Str   d   dt        curr_dt    rd    name
1           Prod  2.00 01/01/01  11/19/13   5.00  Fed
2           Prod  4.50 05/03/02  12/03/13   6.00  Kev
3           Test  6.00 06/07/07  10/02/12   4.00  Sun

tempObj
-----
Client_id    Str   d   dt        curr_dt    rd    name
1           Prod  2.00 01/01/01  11/19/13   5.00  Fed
2           Wen   4.50 05/03/02  07/17/10   1.00  Tom
3           Test  5.00 03/01/07  10/02/12   4.00  Sun

I need to figure out which list element is different that is Str or d or dt or curr_dt or rd or name and whats their value Prod(in first list) and Wen(in second list) and populate the values along with list elements.

Currently I am looping through the list and comparing the values

for (int i= 0; i < Obj.Count; i++)
{
if(Obj[i].Str != tempObj[i].Str)
{
Console.Writeln("Obj Str value" + Obj[i].Str + "tempObj Str value" + tempObj[i].Str);
}
if(Obj[i].d != tempObj[i].d)
{
Console.Writeln("Obj d value" + Obj[i].d + "tempObj d value" + tempObj[i].d);
}
if(Obj[i].dt != tempObj[i].dt)
{
Console.Writeln("Obj dtvalue" + Obj[i].dt+ "tempObj dt value" + tempObj[i].dt);
}
if(Obj[i].rd != tempObj[i].rd)
{
Console.Writeln("Obj rd value" + Obj[i].rd + "tempObj rd value" + tempObj[i].rd);
}
}

It is fine for few number of records but I have huge amount of List elements and data, so I was looking for other options.
