Customizing Web.Config

I am trying to add custom nodes to my web.config file and I am running into a few issues. It looks something like this:

VB Code:

<configuration>
    <configSections>
        <section name="MySection" type="MySectionHandler"/>
    </configSections>
 
 
<MySection>
<CustomNode>1</CustomNode>
<CustomNode>2</CustomNode>
<CustomNode>3</CustomNode>
<CustomNode>4</CustomNode>
</MySection>
...
</configuration>

Then I have the code for mysectionhandler as follows:

VB Code:

Public Class MySectionHandler
    Implements IConfigurationSectionHandler
 
    Public Function Create(ByVal parent As Object, ByVal configContext As Object, ByVal section As System.Xml.XmlNode) As Object Implements System.Configuration.IConfigurationSectionHandler.Create
        Return "HELLO"
    End Function
End Class

Finally, I have my code that trys to display the values:

VB Code:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        TextBox1.Text = ConfigurationSettings.GetConfig("MySection")
 
    End Sub

I am getting an error on the Configuration.GetConfig line. The error I am getting is:

Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately.

Parser Error Message: Exception creating section handler.

It and it highlights the <section name="MySection" type="MySectionHandler"/> line in the Web.Config file.

Anyone seen this before, or can anyone offer any suggestions?

Just a guess since this is an ASP.NET question...
Dont you need a space before the escape char?

VB Code:

<section name="MySection" type="MySectionHandler"/>
 
<section name="MySection" type="MySectionHandler" />

???

Also, is that the complete xml heirachy for your section?

Thanks for the response Rob, but I figured it out. It actually requires the fully qualified name of the object to be created:

<section name="MySection" type="webconfigtest.MySectionHandler,webconfigtest"/>

I changed it and it works.

Cool! Always good to learn something new. Thanks. :)

Ps, now since you solved it yourself you need to give yourself a Rep. :D jk

Hi Guys

Sorry for extending this disucssion but I was looking for a similar solution but in a VB.NET application. Based on your sample <section name="MySection" type="webconfigtest.MySectionHandler,webconfigtest"/> it would appear that webconfigtest is a DLL. I am writing an executable, say vbtest.exe, and wanted to include the Section handler within the same application so I set my section entry as

Code:

---

<section name="MySection" type="MySectionHandler" />

---

but I get an error while retrieving the section data.

I would like to know if the customer section handler class should necessarily be in a seperate DLL?

Thanks for your help.

It doesn't require a separate DLL, however it does require the full name of the object. It is probably ProjectName.Classname in the case of the class in your executable.

Thanks Negative0. It works. I tried

VB Code:

<section name="articlesVB" type="VBNetLab.CustomTagHandler, VBNetLab" />

and it worked. So it would appear that the type part should be something like this:

VB Code:

type="Assembyname.ClassName, AssemblyName"

where Assembly name is the name of the executable.


Thanks
