Question

I am using .net 3.5 . I have a database on which i want to run queries. I am using data adapters or SqlCommand to run the query. But eventually I want the data in row-wise and column-wise string data. What is the way to do that ?
I mean how to extract the data in this way from the dataset(whuich is what is returned by sqlDataAdapter) ? Or is there some other approach to this problem ?

Answer 1

You should look into the DataSet class.

DataSet dataset = new DataSet();
SqlDataAdapter adapter = new SqlDataAdapter();
adapter.SelectCommand = new SqlCommand(
    queryString, connection);
adapter.Fill(dataset);

You access values by method of:

DataSet.Tables["tableName"].Rows[rowIndex]["columnName"]

Or alternatively:

foreach(DataTable table in dataSet.Tables)
{
    foreach(DataRow row in table.Rows)
    {
        foreach (DataColumn column in table.Columns)
        {
            //Do something with
            row[column];
        }
    }
}
