How do I change connection strings of typed dataset in referenced assembly

Question

0.00/5 (No votes)

See more:

I have an application and an assembly. App_1 and ass_1.In ass_1 there are forms and typed datasets referenced from app_1 or any other application so that forms and classes in ass_1 can be called from those apps ie. app_1,app_xx etc. the referencing apps have their own database connections so the referenced assembly (ass_1) has to get its connection string from the referencing app (app_1). Ass_2 will be referenced from GAC (shared) so that different apps can reference it. How do I go about this in C#. ie. dynamically changing connection strings of referenced assembly at runtime. NB: The referenced assembly (ass_1) may have more than one referenced instances runinng at the same time and each instance will have its own connection string from the referencing app (app_1).

This is not a good question - we cannot work out from that little what you are trying to do.
Remember that we can't see your screen, access your HDD, or read your mind.
And that doesn't make a lot of sense to me as it is.
How do the two communicate? What connection string? Why are these separate apps? Or or they referenced assemblies within a single application?

We can help you only if you give us more information as to what type of applications you are talking. I can't see any reason why cant you use a bit information in one app from another app. But need more information.

Solution 1

Either :
1) Read the connection string from a configuration file.
2) Create an interface for your assemblies and pass the connection as a parameter to those assemblies.

Solution 2

Connections should never be part of code.
Read them from any configuration app.config/xml etc.
