How to group multiple array of object in c#

Question

Hi,

 

I am trying to group an array of objects and sum the result of each grouped value.

 

object[] products =

{ new object[] {"Soap", "1" ,10},

new object[] { "Soap", "2", 20 },

new object[] { "Soap1", "1",12 },

new object[] { "Soap", "3",30 },

new object[] { "Soap2", "2" ,10},

new object[] { "Soap1", "2" ,40} };

 

I need the output to be like 

 

Soap    1    10

Soap    2    20

Soap    3    30

-------------------

Total           50 

------------------- 

Soap1  1   12

Soap1   2   40

 -------------------  

Total            52

-------------------- 

Soap2   2   10 

 ------------------

Total            10
