Examples

The following code demonstrates how to use the UseOracle method in the ConfigureServices method of the Startup class.

using Appeon.ApiDoc.Models;
using Microsoft.Extensions.DependencyInjection;
using Oracle.ManagedDataAccess.Client;
using SnapObjects.Data;
using SnapObjects.Data.Oracle;
using System;
using System.Configuration;
using Microsoft.Extensions.Configuration;

namespace Appeon.ApiDoc.OracleExtensionsExamples
{
    public class StartUp
    {
        public IConfiguration Configuration { get; }

        public StartUp(IConfiguration configuration)
        {
            Configuration = configuration;
        }

        const string CONNECTION_STRING = "USER ID=***;PASSWORD=***;" +
        "DATA SOURCE=\"(DESCRIPTION=(ADDRESS=(HOST=***)(PORT=1521)(PROTOCOL=TCP))(CONNECT_DATA=(SERVICE_NAME=***)))\";";

        // This method gets called by the runtime. Use this method to add services to the container.
        public void ConfigureServices(IServiceCollection services)
        {
            // UseOracle with connection string.
            services.AddDataContext<OracleContext>(m => m.UseOracle(CONNECTION_STRING));

            // UseOracle with connection string and other options.
            services.AddDataContext<OracleContext>(m => m.UseOracle(CONNECTION_STRING, n => n.TrimSpaces = true));

            // UseOracle with the IConfiguration object and the key specified in the connection strings.
            services.AddDataContext<OracleContext>(m => m.UseOracle(this.Configuration, "MyConnectionString"));

        }
    }
