Question

I want to store each Datatable Column in a string variable so that i can pass all these parameters to my stored procedure.
This will go on for each row in DataTable

DataTable dtOutput;
dtOutput= Generix.getFeedData(1,ref Connection);
foreach (DataRow drOutput in dtOutput.Rows)
{
    Console.Write("IST: ");
    foreach (DataColumn dcOutput in dtOutput.Columns)
    {
        Console.Write(Convert.ToString(drOutput[dcOutput]) + "\t");
    }
    Console.WriteLine();
}

Above Code should Print Each Column and a "\t" as separator and new row on new line.My DataTable Contains 4 Columns

My DataTable Prints in Following Way:

ATM         Message

ABC001      Hello
ABC002      SAGAR

Now i want in following way:

string sAtm;// Should Print ABC001
string sMsg;//Should Print Hello

For Next Row Value in sAtm will be ABC002

For what it’s worth, you could use Linq to get all params as string.

Pick out what you need:

var allAsString = table.AsEnumerable()
    .Select((r, ri) => new
    {
        Row = r,
        RowNumber = ri,
        Fields = r.ItemArray.Select((f, i) => new 
        {
            Col = table.Columns[i],
            FieldText = string.Format("{0}", f)
        })
    });

So if you for example want to iterate all rows and get specific fields:

foreach (var rowInfo in allAsString)
{
    string sAtm = rowInfo.Fields.First(f => f.Col.ColumnName == "ATM").FieldText;
    string sMsg = rowInfo.Fields.First(f => f.Col.ColumnName == "Message").FieldText; 
}

Remember to add using system.Linq;.

Edit: If you instead want to save the whole DataTable in one string:

String strTable = String.Join(
        Environment.NewLine, 
        table.AsEnumerable().Select(r => String.Join("\t", r.ItemArray)));
