This for customized class to call the ADO.Net. Please use this and let me know if you have any doubts.
public class DbConnectionHelper {
public DataSet DBConnection(string TableName, SqlParameter[] p, string Query, CommandType cmdText) {
string connString = # "your connection string here";
//Object Declaration
DataSet ds = new DataSet();
SqlConnection con = new SqlConnection();
SqlCommand cmd = new SqlCommand();
SqlDataAdapter sda = new SqlDataAdapter();
try {
//Get Connection string and Make Connection
con.ConnectionString = connString; //Get the Connection String
if (con.State == ConnectionState.Closed) {
con.Open(); //Connection Open
}
if (cmdText == CommandType.StoredProcedure) //Type : Stored Procedure
{
cmd.CommandType = CommandType.StoredProcedure;
cmd.CommandText = Query;
if (p.Length > 0) // If Any parameter is there means, we need to add.
{
for (int i = 0; i < p.Length; i++) {
cmd.Parameters.Add(p[i]);
}
}
}
if (cmdText == CommandType.Text) // Type : Text
{
cmd.CommandType = CommandType.Text;
cmd.CommandText = Query;
}
if (cmdText == CommandType.TableDirect) //Type: Table Direct
{
cmd.CommandType = CommandType.Text;
cmd.CommandText = Query;
}
cmd.Connection = con; //Get Connection in Command
sda.SelectCommand = cmd; // Select Command From Command to SqlDataAdaptor
sda.Fill(ds, TableName); // Execute Query and Get Result into DataSet
con.Close(); //Connection Close
} catch (Exception ex) {
throw ex; //Here you need to handle Exception
}
return ds;
}
}
