The most commonly used data operation is encapsulated in the SQLHELPER class in the Data Access Application Block provided by Microsoft. I originally written this for a method of returning a DataSet:
public
Dataset getDepartmentMemberlist (
int
DepartmentID)
{Try {string sql = "OA_Department_GetDepartment_Members"; string conn = ConfigurationSettings.AppSettings [ "strConnection"]; SqlParameter [] p = {SqlHelper.MakeInParam ( "@ departmentID", SqlDbType.Int, 4, departmentID)}; DataSet ds = SQLHELPER.EXECUTEDATASET (CONN, CommandType.StoredProcedure) (SQL, P); Return DS;} catch (system.data.sqlclient.sqlexception ER) {throw new exception (Er.MESSAGE);}
Now I am writing like this:
//
Connection string
Private
String
_ConnectionString
=
ConfigurationSettings.AppSettings [
"
StrConnection
"
];
public
String
Connectionstring
{Get {return this._connectionstring;} set {this._connectionstring = value;}}
public
Dataset getNewStoIndexpage
int
NewstypeID)
{Return getDataSet ("yzb_getnewstoindexpage", getnewstoIndexpage_parameters (newstypeid);}
//
Set stored procedure parameters
Private
Sqlparameter [] getNewStoIndexpage_Parameters
int
NewstypeID)
{SQLParameter [] P = {SQLHELPER.MAKEINPARAM ("@ newstypeid", sqldbtype.int, 4, newstypeid)}; return p;}
//
Here, I really call SQLHELPER.
Private
Dataset getDataSet
String
SQL,
Params
Sqlparameter [] P)
{Return Sqlhelper.executed, CommandType.StoredProcedure, SQL, P);
The code is more flexible, safer: P
