Accessing webreference appSettings from Biztalk BTSNTSvc.exe.config

问题

Sometimes we use global variables in our Biztalk configuration (BTSNTSvc.exe.config), we add these with the following code:

<appSettings>
    <!--<add key="ZNA_Integratie_Prestaties_OasisProxy_OasisServiceProxy_Service"
             value="http://localhost/service.asmx" />-->
    <add key="IPSdatum" value="20090101" />
  </appSettings>

Using the following c# code we can read in the value:

ConfigurationManager.AppSettings["IPSdatum"]

Now normally we when we add a webreference to our biztalk projects we use them through ports, however a colleague of mine used an in code webreference and so added one to a c# class project, so this means there's an app.config where the address is being held. However when we deploy our project there isn't an app.config of course. Only the BTSNTSvc.exe.config. I heard there is a way to add a key value to this config which can refer to the app.config value.

Can anyone help me out here?

回答1:

Option 1:

BTSNTSvc.exe.config file is a .NET config file, you can put the content what you see inside your app.config file inside the BTSNTSvc.exe.config file at the correct sections.

Option 2:

You can refer to additional config files from BTSNTSvc.exe.config file using the app domain concept as explained here

If you are dealing with only few entries, then option 1 is preferable.

Even better, try not to use inline web references within your helper classes, try to avoid the situation.
