To create an object that links a database
SqlConnection myconn = new SqlConnection (Strjet);
Creating adapter Objects
SqlDataAdapter myadapter = new SqlDataAdapter ("Sp_getdataset", myconn);
Indicate as stored procedure
MyAdapter.SelectCommand.CommandType = CommandType.StoredProcedure;
Assigns a value to a stored procedure's STRZD variable, which indicates the query field.
MYADAPTER.SELECTCOMMAND.PARAMETERS.ADD ("@ZDName", SqlDbType.Char). Value = Strzdname;
Assigns a value to a stored procedure's Fromwhere variable, which indicates the query table.
MYADAPTER.SELECTCOMMAND.PARAMETERS.ADD ("@TableName", SqlDbType.Char). Value = strTableName;

Assigns a value to a stored procedure's Wherevalue variable, which indicates the query condition.
MYADAPTER.SELECTCOMMAND.PARAMETERS.ADD ("@WhereValue", SqlDbType.Char). Value = Strwherevalue;

Creating a DataSet Object
DataSet ds = new DataSet ();
Populating data
Myadapter.fill (ds, "Strfromwhere");
Returns a DataSet
return DS;
