不能返回XML格式的字符串，使用C＃和DB模板StringBuilder的，對於一個佔位符

Question

下午好，

我有建立一個字符串在我的數據庫模板輸出的XML結構的功能。它需要一個Order類作爲參數和模板，以及我有麻煩試圖填充名爲[[items]]的佔位符標籤，其中根據表中的項目數量，它應該爲該部分構建xml列表。

這是模板，它只返回字符串的一個實例，但它應該基於表中的內容返回（n）個實例。

<Items> 
    [[items]] 
</Items> 

這是應該填充爲其他標記的項目

<Item> 
<SKU>[[item_sku]]</SKU> 
<PROD_NAME><![CDATA[[[item_product_name]]]]></PROD_NAME> 
<Description><![CDATA[[[item_name]]]]></Description> 
<Attributes><![CDATA[[[item_attributes]]]]></Attributes> 
<Quantity>[[item_qty]]</Quantity> 
<UnitPrice>[[item_price]]</UnitPrice> 
<InkColor>[[item_inkcolor]]</InkColor> 
</Item> 

，它要填充像這樣

<Items> 
    <Item> 
    <SKU>7Z-BRPA-K79A</SKU> 
    <PROD_NAME><![CDATA[Test One]]></PROD_NAME> 
    <Description><![CDATA[ExcelMark 5-Line Large Return Address Stamp - Custom Self Inking Rubber Stamp]]></Description> 
    <Attributes><![CDATA[Custom Text Line 1 Text: This book was donated to CAEO Font: Arial 
       Custom Text Line 2 Text: In tribute to & memory of Font: Arial]]></Attributes> 
    <Quantity>1</Quantity> 
    <UnitPrice><![CDATA[$9.99]]></UnitPrice> 
    <InkColor>Red</InkColor> 
    </Item> 
    <Item> 
    <SKU>42A1848</SKU> 
    <PROD_NAME><![CDATA[Test Two]]></PROD_NAME> 
    <Description><![CDATA[Self Inking Rubber Stamp with up To 4 Lines of Custom Text]]></Description> 
    <Attributes><![CDATA[Custom Text Line 1 Text: This book was donated to CAEO Font: Arial 
       Custom Text Line 2 Text: In tribute to & memory of Font: Arial]]></Attributes> 
    <Quantity>1</Quantity> 
    <UnitPrice><![CDATA[$8.99]]></UnitPrice> 
    <InkColor>Blue</InkColor> 
    </Item> 
</Items> 

這裏是爲了做到這一點

功能

public string PopulateStringBuilder(Order order, Template template) 
    { 
     var i = new StringBuilder(template.Description); 
     List<string> s = new List<string>(); 
     var reqID = order.OrderId; 

      foreach (var x in order.Items) 
      { 
       i.Replace("[[item_sku]]", x.SkuNumber); 
       i.Replace("[[item_product_name]]", x.ProductName); 
       i.Replace("[[item_name]]", x.Description); 
       i.Replace("[[item_attributes]]", x.Attributes); 
       i.Replace("[[item_qty]]", x.Quantity.ToString()); 
       i.Replace("[[item_price]]", x.UnitPrice.ToString()); 
       i.Replace("[[item_inkcolor]]", x.InkColor); 
       o.Replace("[[items]]", i.ToString()); 
      } 
     return o.ToString(); 
    }
