Change property value depending on your type

Question

In my Rest application I receive values via json that are converted to a class

My endpoit

[HttpPost]
[Route("Pessoa/Adicionar")]
public JsonResult AdicionarPessoa([FromBody] PessoaCommand body)
{
     try
     {
     _svcAutentication.Autenticar(Request.Headers["Autentication"].ToString(), Request.Headers["DataBase"].ToString());

     body.TratarValoresRecebidos();

     _svcPessoa.Adicionar(body);

     return new JsonResult(body.TipoPessoa == "F" ? _svcPessoa.BuscarPorCpf(body.Cpf) : _svcPessoa.BuscarPorCnpj(body.Cnpj));
     }
     catch (Exception ex)
     {
          Response.StatusCode = 400;
          return new JsonResult(ex.Message);
     }
}

When sending the request, in case any json field is not filled in, it will arrive in my application with its default value, in case booleans will come as false, numeric types will be converted to 0, strings to null and dates to 0001/01/01

The parse value function serves to convert the string types q will come null to empty string "", and convert the dates that came 0001/01/01 to 1900/01/01 and turns some string fields q came filled in uppercase

As I do a repetitive job, I wonder if there is any way to read all properties of my class and depending on the type of it I do some manipulation, in case the conversion of the null strings to "", string filled with some value do a Toupper (in the case of Tipopessoa and Tipoadvogado) and standard dates (0001/01/01) for 1900/01/01

You can use Reflection for that reason.

With Reflection it is possible to treat an object instance in a generic way, without knowing its type and analyzing its members (properties, methods, etc).

Based on the example of this link: system.reflection.propertyinfo.getvalue? view=net-5.0, the code below takes a class and inspects each property. It is a short example, showing how to change the value of a property DateTime and String, just do the same for the other types and with the values you want:

PessoaCommand teste = new PessoaCommand();
teste.Agencia = "123";

ValidarValores(teste);

private static void ValidarValores(Object obj)
{
    Type t = obj.GetType();
    PropertyInfo[] props = t.GetProperties();

    foreach (var prop in props)
    {
        // Se for data, seta a data atual 
        if (prop.PropertyType == typeof(DateTime))
        {
            prop.SetValue(obj, DateTime.Now);
        }

        // se for string e estiver com o valor default, seta um valor
        if (prop.PropertyType == typeof(String))
        {
            if (prop.GetValue(obj) == default(String)) prop.SetValue(obj, "valor default");
        }
    }
}
