如何从.net框架调用Oracle中的存储过程？

using System;
using Oracle.DataAccess.Client;

class Program
{
    static void Main()
    {
        string connectionString = "Data Source=your_database;User Id=your_username;Password=your_password;";
        
        using (OracleConnection connection = new OracleConnection(connectionString))
        {
            connection.Open();
            
            using (OracleCommand command = connection.CreateCommand())
            {
                command.CommandText = "your_stored_procedure";
                command.CommandType = CommandType.StoredProcedure;
                
                // 添加输入参数
                OracleParameter inputParam = new OracleParameter("input_param", OracleDbType.Varchar2);
                inputParam.Value = "input_value";
                command.Parameters.Add(inputParam);
                
                // 添加输出参数
                OracleParameter outputParam = new OracleParameter("output_param", OracleDbType.Varchar2);
                outputParam.Direction = ParameterDirection.Output;
                command.Parameters.Add(outputParam);
                
                command.ExecuteNonQuery();
                
                // 获取输出参数的值
                string outputValue = outputParam.Value.ToString();
                Console.WriteLine("Output value: " + outputValue);
            }
        }
    }
}
