Question:
i created a data access layer dll using subsonic. however it uses the connectionstring from the app.config. i am using it in ninjatrader and dont want to mess around with the ninjatrader app.config for the connecitonstring. how do i avoid this issue.
Solution:1
I believe the best you can hope for here is to use a separate file for the connection strings:
in app.config
<connectionStrings ConfigSource="myConnStr.config" /> in myConnStr.config:
<connectionStrings > <add .... /> <add .... /> </connectionStrings >
Solution:2
I believe you can set it at runtime using the SetDefaultConnectionString method:
SubSonic.DataService.GetInstance("InstanceName").SetDefaultConnectionString("ConnectionString");
Solution:3
Sample how to programatically hardcode connectionstring:
string connectionString = string.Format(@"Data Source={0}", Path.Combine(this.ConfigFolder, ConfigDb)); string providerName = @"System.Data.SQLite"; var provider = ProviderFactory.GetProvider(connectionString, providerName); _configRepo = new SimpleRepository(provider, SimpleRepositoryOptions.RunMigrations); This sample use sqlite database which is located in this.ConfigFolder. ConfigDB contains name of a database file.
