[Mono-list] ADO.NET Provider Factory

[Brian Ritchie]

Rodrigo,

Thanks for the review.  I guess great minds think alike...I actually already 
had a CreateConnectionFromConfig. :)

Here's the syntax for it:

IDbConnection 
conn=ProviderFactory.CreateConnectionFromConfig("PubsConnStr");

<appSettings>
  <add key="PubsConnStr" value="factory=System.Data.SqlClient; 
server=speedy;database=pubs;uid=sa;pwd=" />
</appSettings>

The factory attribute specifies which provider to use.  I parse out the 
factory attribute, crete the object, and then pass the rest of the 
connection string into the provider. The providers are definited in the 
app.config (or machine.config).

I'll get the code commited sometime today.

Brian
