我有一个嵌套在重复表中的重复表。嵌套表包含 5 列，1 列用于年份，4 列用于不同季度（财务）。如果项目持续时间超过一年，我需要动态地将行添加到嵌套表中。所以如果项目持续 2 年，我需要在嵌套表中添加 2 行并用数据填充它，如果持续 3 年，我需要添加 3 等等。

我似乎无法让嵌套表填充任何数据。我为第一个表使用了一个带有外部 XmlWriter 的循环，并为嵌套表使用了一个嵌套的 XmlWriter。这是一个代码示例：

  public void BuildHwSwForecastRow(string vendor, string description, string totalCost, XPathNavigator root)
    {
        string myNameSpace = NamespaceManager.LookupNamespace("my");

        using (XmlWriter writer = root.SelectSingleNode ("/my:myFields/my:HW_SW_Other_Forecast/my:Forecasts",NamespaceManager).AppendChild())
        {
            writer.WriteStartElement("Forecast", myNameSpace);
            writer.WriteElementString("HSOF-VendorName", myNameSpace, vendor);
            writer.WriteElementString("HSOF-Description", myNameSpace, description);
            writer.WriteElementString("HSOF-TotalCost", myNameSpace, totalCost);

            using (XmlWriter insideWriter = root.SelectSingleNode("//my:HW_SW_Other_Forecast/my:Forecasts/my:Forecast/my:Quarterly_Breakdowns", NamespaceManager).AppendChild())
            {
                insideWriter.WriteStartElement("Quarterly_Breakdown", myNameSpace);
                insideWriter.WriteElementString("HSOF-Year", myNameSpace, "2011");
                insideWriter.WriteElementString("HSOF-Q1", myNameSpace, "");
                insideWriter.WriteElementString("HSOF-Q2", myNameSpace, "");
                insideWriter.WriteElementString("HSOF-Q3", myNameSpace, "");
                insideWriter.WriteElementString("HSOF-Q4", myNameSpace, "");
                insideWriter.WriteEndElement();
                insideWriter.Close();
            }
            writer.WriteElementString("HSOF-Total", myNameSpace, "0.0");
            writer.WriteEndElement();
            writer.Close();
        }
    }

尝试这个。唯一的区别是，第二个使用块在第一个使用块之外。

public void BuildHwSwForecastRow(string vendor, string description, string totalCost, XPathNavigator root)
{
    string myNameSpace = NamespaceManager.LookupNamespace("my");

    using (XmlWriter writer = root.SelectSingleNode ("/my:myFields/my:HW_SW_Other_Forecast/my:Forecasts",NamespaceManager).AppendChild())
    {
        writer.WriteStartElement("Forecast", myNameSpace);
        writer.WriteElementString("HSOF-VendorName", myNameSpace, vendor);
        writer.WriteElementString("HSOF-Description", myNameSpace, description);
        writer.WriteElementString("HSOF-TotalCost", myNameSpace, totalCost);


        writer.WriteElementString("HSOF-Total", myNameSpace, "0.0");
        writer.WriteEndElement();
        writer.Close();
    }

   using (XmlWriter insideWriter = root.SelectSingleNode("//my:HW_SW_Other_Forecast/my:Forecasts/my:Forecast/my:Quarterly_Breakdowns", NamespaceManager).AppendChild())
        {
            insideWriter.WriteStartElement("Quarterly_Breakdown", myNameSpace);
            insideWriter.WriteElementString("HSOF-Year", myNameSpace, "2011");
            insideWriter.WriteElementString("HSOF-Q1", myNameSpace, "");
            insideWriter.WriteElementString("HSOF-Q2", myNameSpace, "");
            insideWriter.WriteElementString("HSOF-Q3", myNameSpace, "");
            insideWriter.WriteElementString("HSOF-Q4", myNameSpace, "");
            insideWriter.WriteEndElement();
            insideWriter.Close();
        }
}
