FastReport.Net：如何动态地在ReportSummaryBand中添加Total

Question

我已经编写了这部分代码来添加字段摘要＆＃34; Count＆＃34;报告摘要带：

Total colTotal = CreateTotal();
colTotal.SetReport(report);
colTotal.PrintOn = reportSummaryBand;                
TextObject colTitle = new TextObject();
colTitle.Text="[" + colTotal.Name + "]";
reportSummaryBand.Objects.Add(colTitle);

CreateTotal函数如下：

private Total CreateTotal()
{
    Total colTotal = new Total();
    colTotal.TotalType = TotalType.SUM, 
    columnHeader.Agg_Func_Type.ToString());
    colTotal.SetName("CountTotal");
    colTotal.Expression = "[MyTable.Count]";
    return colTotal;
}

但我收到错误：   错误CS0103：名称＆＃39; CountTotal＆＃39;在当前上下文中不存在

通过将以下更改应用于CreateTotal函数问题得以解决。希望能帮助到你 ： 感谢Dmitriy Fedyashov为此链接：https://www.fast-report.com/en/blog/68/show/

  private Total CreateTotal(Report report, DataBand dataBand, ReportSummaryBand repSumBand, ColumnHeader columnHeader)
    {
        // create total
        Total colTotal = new Total();
        colTotal.SetName("CountTotal");
        colTotal.Expression = "[MyTable.Count]";
        colTotal.Evaluator = dataBand;
        colTotal.PrintOn = repSumBand;
        colTotal.TotalType = TotalType.Sum;                  

        report.Dictionary.Totals.Add(colTotal);
        return colTotal;
    }
