asp.net – 抛出类型“System.OutOfMemoryException”的异常 为

错误发生在这里：

public static DataSet GetDataSet(string databaseName,string
                                   storedProcedureName,params object[] parameters)
    {
        //Creates blank dataset
        DataSet ds = null;

        try
        {
            //Creates database
            Database db = DatabaseFactory.CreateDatabase(databaseName);
            //Creates command to execute
            DbCommand dbCommand = db.GetStoredProcCommand(storedProcedureName);
            dbCommand.CommandTimeout = COMMAND_TIMEOUT;
            //Returns the list of SQL parameters associated with that stored proecdure
            db.DiscoverParameters(dbCommand);

            int i = 1;
            //Loop through the list of parameters and set the values
            foreach (object parameter in parameters)
            {
                dbCommand.Parameters[i++].Value = parameter;
            }
            //Retrieve dataset and set to ds
            ds = db.ExecuteDataSet(dbCommand);
        }
            //Check for exceptions
        catch (SqlException sqle)
        {
            throw sqle;
        }
        catch (Exception e)
        {
            throw e; // Error is thrown here.
        }
        //Returns dataset
        return ds;
    }

这是按钮上运行的代码点击：

protected void btnSearchSBIDatabase_Click(object sender,EventArgs e)
{

        LicenseSearch ls = new LicenseSearch();

        DataTable dtSearchResults = new DataTable();

        dtSearchResults = ls.Search();

        Session["dtSearchResults"] = dtSearchResults;

        Response.Redirect("~/FCCSearch/SearchResults.aspx");
        }
        else
            lblResults.Visible = true;
    }
