初學者的LINQ to XML內聯XML錯誤

Question

Imports System.Xml.Linq 
Imports System.Linq 

Partial Class test2 
    Inherits System.Web.UI.Page 

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load 
     Dim xml As XElement = <book> 
            <title>My Title</title> 
            <author>Kyle</author> 
            <publisher>WROX</publisher> 
           </book> 
    End Sub  
End Class 

上面的代碼產生以下錯誤：

Compiler Error Message: BC30201: Expression expected. 

Source Error: 

Line 8: 
Line 9:  Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load 
Line 10:   Dim xml As XElement = <book> 
Line 11:         <title>My Title</title> 
Line 12:         <author>Kyle</author> 


Source File: C:\Inetpub\wwwroot\myproject\web\test2.aspx.vb Line: 10 

爲什麼？

編輯：

Dim xml As XElement = New XElement("book", _ 
       New XElement("title", "My Title"), _ 
       New XElement("author", "Kyle"), _ 
       New XElement("publisher", "WROX") _ 
      ) 

上面的代碼工作，但顯然不如原來的優雅和我仍然會欣賞爲什麼我原來的語法是錯誤的解釋。

Answer 1

的代碼工作正常，我原樣，但也許嘗試啓動XML文本上新線？

Dim xml As XElement = _ 
      <book> 
       <title>My Title</title> 
       <author>Kyle</author> 
       <publisher>WROX</publisher> 
      </book> 

Answer 2

我不熟悉VB語法，但不要你必須做類似

Dim xml as XElement = new XElement(<book>... etc)? 

Answer 3

我有同樣的問題，因爲它證明我的項目運行在2.0，即使它被設置爲目標3.5。
