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);
