將輸出與Linq間隔到Xml

Question

如何使用Linq to Xml強制某些節點之間的額外間距？我期望輸出以下內容：

<root> 

    <group> 
     <leaf /> 
    </group> 

    <group> 
     <leaf /> 
    </group> 

</root> 

通過添加空XText，它只會破壞格式。

var root = 
    new XElement("root", 
     new XText(""), 
     new XElement("group", 
      new XElement("leaf")), 
     new XText(""), 
     new XElement("group", 
      new XElement("leaf")), 
     new XText("")); 

Console.WriteLine(root.ToString()); 

導致

<root><group><child /></group><group><child /></group></root> 

Answer 1

這是一個解決方案，但it's不漂亮...

變化XTEXT到XComment，做這樣的事情...

    var root = 
     new XElement("root", 
      new XComment(""), 
      new XElement("group", 
       new XElement("leaf")), 
      new XComment(""), 
      new XElement("group", 
       new XElement("leaf")), 
      new XComment("")); 

    Console.WriteLine(XElementToText(root)); 


    private string XElementToText(XElement element) 
    { 
     var sb = new StringBuilder(); 
     using (var writer = XmlWriter.Create(sb, 
      new XmlWriterSettings {Indent = true})) 
     { 
      element.WriteTo(writer); 
     } 
     return sb.ToString().Replace("<!---->", string.Empty); 
    } 

編輯：福格特逃跑比...

Answer 2

傳遞一個XmlTextWriter（與Formatting設置爲Formatting.Indented）至root.WriteTo()。

例如：

using(var writer = new XmlTextWriter(Console.Out)); 
{ 
    writer.Formatting = Formatting.Indented; 
    root.WriteTo(writer); 
} 

Answer 3

using (var writer = XmlWriter.Create(
    Console.Out, 
    new XmlWriterSettings { Indent = true }) 
{ 
    root.WriteTo(writer); 
}
