        <section name="rptBuildProvider" type="CrystalDecisions.Shared.RptBuildProviderHandler, CrystalDecisions.Shared, Version=13.0.2000.0, Culture=neutral, PublicKeyToken=692fbea5521e1304, Custom=null" />
        <section name="crystalReportViewer" type="System.Configuration.NameValueSectionHandler" />
      </sectionGroup>
    </sectionGroup>
  </configSections>

接下来，为ASP.NET MVC项目添加一页网页是asp.net 的ASPX，网页名为CurrencyReport.aspx，它自带有CurrencyReport.aspx.cs如下图。

对这页网页暂时不需添加任何代码，稍后创建好.Rpt报表后再来写代码。

现在开始创建.rpt水晶报表：

报表创建完毕，此时打开上面创建的ASPX网页。

再打开.aspx.cs代码页，编写加载水晶报表程序：

 string reportPath = Server.MapPath("CurrencyReport.rpt");
            ReportDocument repDoc = new ReportDocument();

            try
            {
                if (!File.Exists(reportPath))
                {
                    Response.Write("指定的报表不存在。 \n");
                }

                repDoc.Load(reportPath);

                repDoc.SetDatabaseLogon("username", "password", "127.0.0.1", "DBname", true);
                this.CrystalReportViewer1.ToolPanelView = CrystalDecisions.Web.ToolPanelViewType.None;
                this.CrystalReportViewer1.HasToggleGroupTreeButton = false;
                this.CrystalReportViewer1.ReportSource = repDoc;
                
            }
            catch (Exception ex)
            {
                Response.Write(ex.Message);
            }
