如何为dotNET核心控制台应用设置Oracle连接字符串？

{
  "ConnectionStrings": {
    "OracleConnection": "Data Source=your_oracle_server;User Id=your_username;Password=your_password;"
  }
}

using Microsoft.Extensions.Configuration;
using Oracle.ManagedDataAccess.Client;

class Program
{
    static void Main(string[] args)
    {
        var config = new ConfigurationBuilder()
            .AddJsonFile("appsettings.json")
            .Build();

        var connectionString = config.GetConnectionString("OracleConnection");

        using (var connection = new OracleConnection(connectionString))
        {
            // 连接到Oracle数据库并执行操作
        }
    }
}
