How can we filter datatable in c#?

Question

I have specific requirement with datatable which i am not able to get. Please help me to solve my problem. My query is as below

1. The datatable i have with data is

  C1 C2 C3 C4 C5 R1 1 2 3 4 25 R2 6 7 8 24 10 R3 11 22 13 14 15 R4 16 17 23 19 20 R5 21 7 18 9 5 

2. In output i would like to have max value from each colum with position (index) of row and colum as following

 Value Row Column 21 R5 C1 22 R3 C2 23 R4 C3 24 R2 C4 25 R1 C5 

Can anyone please help me, how should i achieve result?

Answer 1

Assuming column names are C1, C2, C3, C4, C5.

Pseudo code/Algorithm.

int C1_MaxValue, C2_MaxValue, C3_MaxValue, C4_MaxValue, C5_MaxValue;
string C1_Row, C2_Row, C3_Row, C4_Row, C5_Row;

//Initialize row1 values as max values.
C1_MaxValue = DataTable.Rows[1]["C1"];
C2_MaxValue = DataTable.Rows[1]["C2"];
C3_MaxValue = DataTable.Rows[1]["C3"];
C4_MaxValue = DataTable.Rows[1]["C4"];
C5_MaxValue = DataTable.Rows[1]["C5"];

//Set R1 as row for max values.
C1_Row = C2_Row = C3_Row = C4_Row = C5_Row = DataTable.Rows[1][Row1];

For (i=2 to RowCount -1)

 if(Datatable.Rows[i]["C1"] > C1_MaxValue) 
 {       
      C1_MaxValue = Datatable.Rows[i][C1]; 
      C1_Row = Datatable.Rows[i][0];
 }
 //Do the above for all other columns.
End For

At the end of this for the above variables should contain the max values and corresponding max rows.
