我正在使用Crystal Report（版本10）开发一个简单的应用程序，并且 .NET Framework 4.0 以及 VS 2010;我在 c# 中创建水晶报告 使用存储过程的视窗应用程序;我的存储过程名称 是"GetByCodeService"，参数是"codeService"。

我运行我的 项目，但我的项目在该行中出现错误"加载报告失败"。 ： "RepDoc.Load（RepPath）;"！

            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();
            ReportDocument RepDoc = new ReportDocument();
            connectionInfo.ServerName = ".";
            connectionInfo.DatabaseName = "taxi1";
            string RepPath = Application.StartupPath + @"CrystalReport2.rpt";
            RepDoc.Load(RepPath);
            RepDoc.SetDataSource(ds);
            crystalReportViewer1.ReportSource = RepDoc;
            ParameterValues parameterValues = new ParameterValues();
            ParameterDiscreteValue parameterDiscreteValue = new ParameterDiscreteValue();
            parameterDiscreteValue.Value = Id;
            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")
