水晶報表和C＃

Question

當我運行包含Crystal Report的C＃Windows窗體應用程序時 。 它要求我每次輸入MySQL數據庫的憑據 。 即使我輸入了正確的用戶名和密碼。 這表示我的用戶名或密碼錯誤 。 我已經多次檢查憑證，並且輸入的密碼正確。

Answer 1

請遵循此說明。

            TableLogOnInfos TableLogOnInfos = new TableLogOnInfos();
            TableLogOnInfo TableLogOnInfo = new TableLogOnInfo();
            ConnectionInfo ConnectionInfo = new ConnectionInfo();
            Tables Tables;
            ConnectionInfo.ServerName = "ServerName";
            ConnectionInfo.DatabaseName = "Database";
            ConnectionInfo.UserID = "UserId";
            ConnectionInfo.Password = "Password";
            ReportDocument report = new ReportDocument();
            string reportPath = Server.MapPath("~/CrystalReport Path");
            report.Load(reportPath);
            Tables = report.Database.Tables;
            foreach (CrystalDecisions.CrystalReports.Engine.Table table in Tables)
            {
                TableLogOnInfo = table.LogOnInfo;
                TableLogOnInfo.ConnectionInfo = ConnectionInfo;
                table.ApplyLogOnInfo(TableLogOnInfo);
            }
            CrystalReportViewer1.RefreshReport();
            CrystalReportViewer1.ReportSource = report;

同時加載報告時，將始終設置連接字符串。
