using Appeon.ApiDoc;
using SnapObjects.Data;

namespace Appeon.ApiDoc.ParamValueExamples
{
    public class InputOutputExample
    {
        private readonly SchoolContext _context;
        
        public InputOutputExample(SchoolContext context)
        {
            _context = context;
        }

        public async void Example2()
        {
            // Specifies the procedure to be executed.
            string procedureName = "InputOutputTest";
            
            ParamValue Param = ParamValue.Input<int>("id", 4);
            
            ParamValue nameParam = ParamValue.InputOutput("name", "test", typeof(string));
            
            // Gets and shows the attribute value of the ParamValue object
            Console.WriteLine("ParamValue.Name = {0}", nameParam.Name);
            Console.WriteLine("ParamValue.Direction = {0}\n", nameParam.Direction);
            
            Console.WriteLine("Before Executes the SQL statement:");
            Console.WriteLine("ParamValue.Value = {0}\n", nameParam.Value);
            
            // Asynchronously Executes the SQL statement and gets the department by
            // nameParam.
            int rowAffected = await _context.SqlExecutor.ExecuteProcedureAsync(
                    procedureName, Param, nameParam);
                    
            Console.WriteLine("After Executes the SQL statement:");
            Console.WriteLine("ParamValue.Value = {0}", nameParam.Value);
            
            /*This code produces the following output:
            
                ParamValue.Name = name
                ParamValue.Direction = InputOutput
                
                Before Executes the SQL statement:
                ParamValue.Value = test
                
                After Executes the SQL statement:
                ParamValue.Value = Mathematics
