Crystal 报告和 C#

Question

当我运行我的 C# windows form application that contains Crystal Report. It's asking me to enter the credential for the MySQL db every time. Even though I entered the correct user name and password. it is saying my user name or password is wrong。我已经检查了很多次凭据，输入的密码是正确的。

按照此说明操作。

            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;

同时加载报表时，始终会设置连接字符串。
