Provider connection string from Entity Framework

Provider connection string from Entity Framework

To get the provider connection string from Entity Framework in C#, you can use the EntityConnectionStringBuilder class. The EntityConnectionStringBuilder class parses an Entity Framework connection string and provides access to the provider connection string.

Here's an example of how to use the EntityConnectionStringBuilder class:

using System.Data.Entity.Core.EntityClient; string GetProviderConnectionString(string entityConnectionString) { // Parse the Entity Framework connection string var entityBuilder = new EntityConnectionStringBuilder(entityConnectionString); // Get the provider connection string return entityBuilder.ProviderConnectionString; }

In this example, we define a method called GetProviderConnectionString that takes a string parameter called entityConnectionString, which is the Entity Framework connection string that you want to parse.

We create a new EntityConnectionStringBuilder object and pass in the entityConnectionString. We then use the ProviderConnectionString property of the EntityConnectionStringBuilder object to get the provider connection string.

Note that the ProviderConnectionString property returns the provider connection string as a string. You may need to further parse or modify the provider connection string depending on your needs.
