十六进制值不能包含在名称VB.NET中 [英] Hexadecimal values cannot be included in a name VB.NET

问题描述

我正在尝试编写一个代码来插入现有xml文件中的项目，我希望文件中的项目如下：

I'm trying to write a code to insert items in exist xml file ,I want the items in file to be like this:

<item>
  <title><![CDATA[any title]]></title>
  <link>http://any link</link>
  <pubDate>any date</pubDate>
  <guid isPermaLink="true">any link</guid>
  <description><![CDATA[any description]]></description>
        <media:credit role="author"><![CDATA[any author]]></media:credit>
  <media:category><![CDATA[any category]]></media:category>
  <media:content url="http://any link" height="266" width="127" /> 
  <media:thumbnail url="http://any link" height="266" width="127" />
</item>

所以我写了这段代码：

so I have write this code :

Dim FilePath As String
        FilePath = "C:\Users\MONZER\Desktop\Karary Web Site\WebApplication1\XMLFile1.xml"
        Dim document As New XDocument
        If File.Exists(FilePath) Then
            document = XDocument.Load(FilePath)
        Else
            Label1.Text = "not done"
        End If

        Dim root = New XElement("item")
        Dim title = New XElement("title", "<![CDATA[" & TextBox3.Text & "]]>")
        Dim link = New XElement("link", TextBox6.Text)
        Dim pubDate = New XElement("pubDate", DateTime.Now.ToString("yyy/MM/dd HH:mm"))
        Dim description = New XElement("description", TextBox5.Text)
        Dim author = New XElement("media:credit",
                                      New XAttribute("role", "author"),
                                      New XAttribute("><![CDATA[", TextBox5.Text + "]]>"))

        root.Add(title, link, pubDate, description, author)
        document.Root.Add(root)
        document.Save(FilePath)
        Label1.Text = "done"

    End Sub

我收到此错误：

'：'字符，十六进制值0x3A，不能包含在名称中。



我尝试了什么：



将ab定义为xnamespace

ab =media：credit然后使用它像：

Dim author = New XElement（ab.tostring，

New XAttribute（role，author），

新的XAttribute（><！[CDATA [，TextBox5.Text +]]>））

但是也没有用！

I got this error :
The ':' character, hexadecimal value 0x3A, cannot be included in a name.

What I have tried:

define ab as xnamespace
ab="media:credit" then use it like :
Dim author = New XElement(ab.tostring,
New XAttribute("role", "author"),
New XAttribute("><![CDATA[", TextBox5.Text + "]]>"))
but did not work either!

推荐答案

Quote：

Hexadecimal values cannot be included in a name VB.NET

没有仔细阅读错误信息！

No read carefully the error message !

Quote：

'：'字符，< b>其十六进制值为0x3A，不能包含在名称中。

The ':' character, which have an hexadecimal value of 0x3A, cannot be included in a name.

字符名称为 column'：'

此字符由操作系统保留，不能用于文件名。

The character name is column ':'
This character is reserved by OS and can't be used in a filename.

您正在尝试将元素命名为media：credit。你不能这样做。取出冒号并将元素重命名为其他内容。

You're trying to name an element "media:credit". You can't do that. Take the colon out and rename the element to something else.
