使用LINQ

Question

在C＃中添加的XElement XML元素/節點裏面我想創建一些XML這種格式

<root> 
<columns> 
    <column name="name1" value="value1" /> 
    <column name="name2" value="value2" /> 
    <column name="name3" value="value3" /> 
    ... 
</columns> 
<rows> 
    <row name="name1" value="value1" /> 
    <row name="name2" value="value2" /> 
    <row name="name3" value="value3" /> 
    ... 
</rows> 
</root> 

，所以我創建

XElement tree = new XElement("root", new XElement("columns", from c in columns select new XElement("column", c) ... 

，其結果是

<root> 
<columns> 
    <column> 
    <column> 
    <column> 
    ... 
    </column> 
    </column> 
    </columns> 
... 
</root> 

我如何關閉一個節點的孩子或東西有我想要的？

Answer 1

以下代碼：

List<KeyValuePair<string, string>> columns = new Dictionary<string,string> { 
    {"name1", "value1"}, 
    {"name2", "value2"}, 
    {"name3", "value3"} 
}.ToList(); 

XElement tree = 
    new XElement("root", 
     new XElement("columns", 
      from c in columns 
      select new XElement("column", 
       new XAttribute("name", c.Key), 
       new XAttribute("value", c.Value) 
      ) 
     ), 
     new XElement("rows", 
      from r in rows // same dictionary as columns 
      select new XElement("row", 
       new XAttribute("name", r.Key), 
       new XAttribute("value", r.Value) 
      ) 
     ) 
    ); 

主要生產所需的XML：

<root> 
    <columns> 
    <column name="name1" value="value1" /> 
    <column name="name2" value="value2" /> 
    <column name="name3" value="value3" /> 
    </columns> 
    <rows> 
    <row name="name1" value="value1" /> 
    <row name="name2" value="value2" /> 
    <row name="name3" value="value3" /> 
    </rows> 
</root> 

Answer 2

XElement tree = new XElement("root", 
    new XElement("columns", 
     from c in columns 
     select new XElement("column", new XAttribute("name", c.Name,), new XAttribute("value", c.Value))), 
    new XElement("rows", 
     from r in rows 
     select new XElement("row", new XAttribute("name", r.Name,), new XAttribute("value", r.Value))));
