ASP.net Mvc with multiple database connections

Question

How can I access multiple databases in a single project for inserting data at the same time? Is it possible to use different connection strings in a single web.config file?

Answer 1

Yes it is possible.Use connectionStrings section in web.config

<connectionStrings>
  <add name="connection1" connectionString="Your Connection string" providerName="Your provider name"/>
  <add name="connection2" connectionString="Your Connection string" providerName="Your provider name"/>
  <add name="connection3" connectionString="Your Connection string" providerName="Your provider name"/>
 </connectionStrings>

use this connection string in your project as

ConfigurationManager.ConnectionStrings["Your connection string name"].ToString()

Answer 2

Yes you can,

By adding many connection strings in your web.config file

As:

<connectionStrings>
  <add name="connection1" connectionString="First Connection string" providerName="Your provider name"/>
  <add name="connection2" connectionString="Second Connection string" providerName="Your provider name"/>
 </connectionStrings>

and in your code, you can call wich connection String you want as:

ConfigurationManager.ConnectionStrings["First Connection string"].ToString()

or

ConfigurationManager.ConnectionStrings["Second Connection string"].ToString()
