我正在使用Crystal Report（第10版）开发一个简单的应用程序 .NET Framework 4.0以及VS 2010;我在c＃中创建水晶报告 windows应用程序使用存储过程;我的存储过程名称是＆＃34; GetByCodeService＆＃34;并且那个参数是＆＃34; codeService＆＃34;。

我跑了我的项目，但我的项目有错误＆＃34;加载报告失败。＆＃34;在线：＆＃34; RepDoc.Load（RepPath）;＆＃34;！

            con.ConnectionString = "Data Source =.;Initial Catalog=taxi1; Integrated Security=True";
            cmd.Connection = con;
            cmd.CommandType = CommandType.StoredProcedure;
            cmd.CommandText = "GetByCodeService";
            int Id = Convert.ToInt16(textBox1.Text);
            SqlParameter ld = new SqlParameter("@codeService", Id);
            cmd.Parameters.Add(ld);
            SqlDataAdapter dataadapter = new SqlDataAdapter();
            dataadapter.SelectCommand = cmd;
            DataSet ds = new DataSet();
            dataadapter.Fill(ds);

            ConnectionInfo connectionInfo = new ConnectionInfo();

            parameterValues.Add(parameterDiscreteValue);
            ParameterFieldDefinitions parameterFieldDefinitions = RepDoc.DataDefinition.ParameterFields;
            ParameterFieldDefinition parameterFieldDefinition = parameterFieldDefinitions["@codeService"];
           parameterFieldDefinition.ApplyCurrentValues(parameterValues);

            ConnectionInfo connectionInfo = new ConnectionInfo();
            ReportDocument RepDoc = new ReportDocument();
            connectionInfo.ServerName = ".";
            connectionInfo.DatabaseName = "taxi1";
            string RepPath = Path.Combine(Application.StartupPath,"CrystalReport2.rpt")
            RepDoc.Load(RepPath);
            RepDoc.SetDataSource(ds);
            crystalReportViewer1.ReportSource = RepDoc;

将Application.StartupPath + @"CrystalReport2.rpt"更改为Path.Combine(Application.StartupPath,"CrystalReport2.rpt")

如何在Crystal Reports版本10中删除加载报告失败错误？
