System.Configuration avec le fichier .config séparé

Question

J'ai pris le code de cet exemple.

http://msdn.microsoft.com/en-us/library/2tw134k3.aspx

Ce que je me demande (et je suis allé partout dans la recherche Internet aujourd'hui) ... Comment obtenez-vous que pour être dans un fichier externe (séparé).

L'idée que je vais faire est:

<configuration> 
    <configSections> 
    <sectionGroup name="pageAppearanceGroup"> 
     <section 
     name="pageAppearance" 
     type="HelperAssembly.Configuration.PageAppearanceSection,HelperAssembly" 
     allowLocation="true" 
     allowDefinition="Everywhere" 
     /> 
    </sectionGroup> 
    </configSections> 


    <pageAppearanceGroup fileName="SomeSeparateFile.config"/> 

</configuration> 

..................

qui précède ne fonctionne pas (bien sûr).

Ci-dessous est mon copiage/collage de l'article ms mentionné ci-dessus. Et ça fonctionnait complètement quand je l'ai collé ici.

Answer 1

Essayez d'utiliser le configSource

Cela fonctionnera si vous changez votre app.config utiliser ceci:

<?xml version="1.0" encoding="utf-8" ?> 
<configuration> 
    <configSections> 
    <sectionGroup name="pageAppearanceGroup"> 
     <section 
     name="pageAppearance" 
     type="HelperAssembly.Configuration.PageAppearanceSection,HelperAssembly" 
     allowLocation="true" 
     allowDefinition="Everywhere" 
     /> 
    </sectionGroup> 
    </configSections> 

    <pageAppearanceGroup> 
    <pageAppearance configSource="SomeSeparateFile.config"/> 
    </pageAppearanceGroup> 

</configuration> 

Et votre someSeparateFile. config pour ressembler à ceci:

<pageAppearance remoteOnly="true"> 
    <font name="TimesNewRoman" size="18"/> 
    <color background="123456" foreground="ABCDEF"/> 
</pageAppearance> 

(aucun élément configuration dans ce fichier!)

J'ai été en mesure de se déplacer configSections dans des fichiers séparés. Vous n'êtes pas sûr de pouvoir le faire avec configGroups à moins de faire beaucoup plus de programmation. Le modèle de cadre de configuration vous permet de déplacer configSections assez facilement.

Espérons que cela aide !!
