Usage

This snippet directly configures a Oracle database connection for an Entity Framework Core DbContext using a connection string.

public class MyDbContext : DbContext {
 
  protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder) {

     optionsBuilder.UseOracle(@"UserId=demo;Password=test;ServiceName=orcl;Server=127.0.0.1;Port=1521;");
  } 
}

Configuration Using OracleConnection Instance

using Devart.Data.Oracle;
...

public class MyDbContext : DbContext {
 
  protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder) {

     var connection = new OracleConnection();
     connection.Direct = true;
     connection.Host = "127.0.0.1";
     connection.ServiceName = "orcl";
     connection.Port = 1521;
     connection.UserId = "demo";
     connection.Password = "test";
     optionsBuilder.UseOracle(connection);
  } 
}

This snippet simplifies the connection setup by directly assigning a connection string to the ConnectionString property of the OracleConnection object

connection.ConnectionString = "UserId=demo;Password=test;Server=127.0.0.1;";

ASP.NET Core and Blazor

Configuration File Snippet (appsettings.json):

{
  "ConnectionStrings": {
    "DefaultConnection": "UserId=demo;Password=test;Server=127.0.0.1;Port=1521;"
   }
}

Dependency Injection of IConfiguration:

private readonly IConfiguration configuration;

public YourController(IConfiguration config) 
{
    configuration = config;
}

Retrieving a Connection String:

var connectionString = configuration.GetConnectionString("DefaultConnection");
var connection = new OracleConnection(connectionString);
