Columns and rows not adding dynamicaly in C# Datatable

I am learning about dynamic datatable creation from stored procedure results in C#, but I ran into a problem. I have a stored procedure which returns 2 tables as result, by using this table I need to create a separate datatable in C#. I am not able to dynamically add all the columns and rows in multiple data tables.

Function 1

public ExcelReportDetails createdataset()

{

DataSet ds = new DataSet();

ds = DataAdapter.SPArray2(storedProcedure);

}

Here in `ds`, I should get the dataset with all tables with values.

Function 2

public static DataSet SPArray2(string storedProcedureName)

{

DataSet Owndataset = new DataSet();

using (DataSet dataSet = ExecuteDataSet(cmd => ConfigureStoredProcCommand(cmd, storedProcedureName)))

{

Owndataset = dataSet.ToDataSet2();

}

return Owndataset;

}

Function 3

public static DataSet ToDataSet2(this DataSet dataset)

{

DataSet ownds2 = new DataSet();

for (var i = 0; i < dataset.Tables.Count; i++) //getting table count as 2. I am returning from stored procedure like key value pair.key-country,value-india

{

using (var table = dataset.Tables[i])

{

ownds2.Tables.Add( table.ToDataTable2());

}

}

return ownds2;

}

Function 4

public static DataTable ToDataTable2(this DataTable table)

{

DataTable owntable = new DataTable();

if (table.Rows.Count > 0)

{

for (var row = 0; row < table.Rows.Count; row++)

{

for (int i = 0; i < table.Columns.Count; i++)

{

owntable.Columns.Add(table.Columns[i]); // how do I add columns confused here

owntable.Rows.Add(table.Rows[row][i]); // how do I add rows confused here

}

}

}

return owntable;

}

Thanks a lot!
