ストアドプロシージャとパラメーターでDataAdapterを使用する方法

DataAdapterを使用してDataGridViewコントロールを設定します。しかし、パラメータ付きのストアドプロシージャを使用しているため、その方法はわかりません。誰か例を挙げてください。

わかった！...

protected DataTable RetrieveEmployeeSubInfo(string employeeNo)
        {
            SqlCommand cmd = new SqlCommand();
            SqlDataAdapter da = new SqlDataAdapter();
            DataTable dt = new DataTable();
            try
            {
                cmd = new SqlCommand("RETRIEVE_EMPLOYEE", pl.ConnOpen());
                cmd.Parameters.Add(new SqlParameter("@EMPLOYEENO", employeeNo));
                cmd.CommandType = CommandType.StoredProcedure;
                da.SelectCommand = cmd;
                da.Fill(dt);
                dataGridView1.DataSource = dt;
            }
            catch (Exception x)
            {
                MessageBox.Show(x.GetBaseException().ToString(), "Error",
                        MessageBoxButtons.OK, MessageBoxIcon.Error);
            }
            finally
            {
                cmd.Dispose();
                pl.MySQLConn.Close();
            }
            return dt;
        }

たぶん、あなたのコードはMicrosoftの例からこの行が抜けている：

MyDataAdapter.SelectCommand.CommandType = CommandType.StoredProcedure

    SqlConnectionStringBuilder builder = new SqlConnectionStringBuilder();
        builder.DataSource = <sql server name>;
        builder.UserID = <user id>; //User id used to login into SQL
        builder.Password = <password>; //password used to login into SQL
        builder.InitialCatalog = <database name>; //Name of Database

        DataTable orderTable = new DataTable();

        //<sp name> stored procedute name which you want to exceute
        using (var con = new SqlConnection(builder.ConnectionString))
        using (SqlCommand cmd = new SqlCommand(<sp name>, con)) 
        using (var da = new SqlDataAdapter(cmd))
        {
            cmd.CommandType = System.Data.CommandType.StoredProcedure;
            //Data adapter(da) fills the data retuned from stored procedure 
           //into orderTable
            da.Fill(orderTable);
        }

さあ、

DataSet ds = new DataSet();
SqlCommand cmd = new SqlCommand();
cmd.Connection = con; //database connection
cmd.CommandText = "WRITE_STORED_PROC_NAME"; //  Stored procedure name
cmd.CommandType = CommandType.StoredProcedure; // set it to stored proc
//add parameter if necessary
cmd.Parameters.Add("@userId", SqlDbType.Int).Value = courseid;

SqlDataAdapter adap = new SqlDataAdapter(cmd);
adap.Fill(ds, "Course");
return ds;

   public DataSet Myfunction(string Myparameter)
    {
        config.cmd.Connection = config.cnx;
        config.cmd.CommandText = "ProcName";
        config.cmd.CommandType = CommandType.StoredProcedure;
        config.cmd.Parameters.Add("parameter", SqlDbType.VarChar, 10);
        config.cmd.Parameters["parameter"].Value = Myparameter;

        config.dRadio = new SqlDataAdapter(config.cmd);
        config.dRadio.Fill(config.ds,"Table");

        return config.ds;


    }
