Set Entity Framework Connection String at Runtime in C#

Question

I need to set my Entity Framework connection string at runtime. Right now, I have the following:

string connectionString = \"metadata=res://*/DataModels.Cust         


        

Answer 1

Change this.

string connectionString = "metadata=res://*/DataModels.CustomerDataModel.csdl|res://*/DataModels.CustomerDataModel.ssdl|res://*/DataModels.CustomerDataModel.msl;provider=System.Data.SqlClient;provider connection string="data source=tcp:{serverName},{portNumber};initial catalog={databaseName};user id={username};multipleactiveresultsets=True;application name=EntityFramework"";

To this (note how i escaped the " character as "" )

string connectionString = @"metadata=res://*/DataModels.CustomerDataModel.csdl|res://*/DataModels.CustomerDataModel.ssdl|res://*/DataModels.CustomerDataModel.msl;provider=System.Data.SqlClient;provider connection string= ""data source=tcp:{serverName},{portNumber};initial catalog={databaseName};user id={username};multipleactiveresultsets=True;application name=EntityFramework""";
