How to turn an object into a request in C#-CodePudding

My Model, example:

public class Obj
    {
        public Obj()
        { }
        public int? IdRestricao { get; set; }
        public int? IdTipoRestringido { get; set; }
        public string CodRestringido { get; set; }
        public string NomeRestringido { get; set; }
        public int? IdTipoRestricao { get; set; }
        public string CodRestricao { get; set; }
        public string NomeRestricao { get; set; }
        public DateTime? PeriodoInicio { get; set; }
        public DateTime? PeriodoFim { get; set; }
        public int? IdStatus { get; set; }
    }

Request

www.url.com.br?IdRestricao=1&IdTipoRestringido=2&CodRestringido=3&NomeRestringido=4&IdTipoRestricao=5&CodRestricao=6&NomeRestricao=7&PeriodoInicio=8&PeriodoFim=9

code:

var model = obj.*tostring()*// 
something like    
var request = new RestRequest($"/api/{**model**}", Method.GET);

edit1:

I'm wondering if there is a library or something that transforms my object in my request as in the examples above

CodePudding user response：

You can override ToString to format the data from the Obj class into GET parameters.

You could write a utility function to convert all object properties into nameof and the associated value into key-value pairs.

Something such as this answer to convert your Obj into a dictionary, and then another method to convert the dictionary into Prop=value could be done.

For a one off something like this would be suitable:

public override string ToString()
{
    return $"IdRestricao={IdRestricao}&IdTipoRestringido={IdTipoRestringido}&CodRestringido={CodRestringido}...
}

I found the answer to what I was looking for, it follows below in case anyone needs it in the future

private static string ToQueryString(this object request, string separator = ",")
        {
            if (request == null)
                throw new ArgumentNullException("request");

            // Get all properties on the object
            var properties = request.GetType().GetProperties()
                .Where(x => x.CanRead)
                .Where(x => x.GetValue(request, null) != null)
                .ToDictionary(x => x.Name, x => x.GetValue(request, null));

            // Get names for all IEnumerable properties (excl. string)
            var propertyNames = properties
                .Where(x => !(x.Value is string) && x.Value is IEnumerable)
                .Select(x => x.Key)
                .ToList();

            // Concat all IEnumerable properties into a comma separated string
            foreach (var key in propertyNames)
            {
                var valueType = properties[key].GetType();
                var valueElemType = valueType.IsGenericType
                                        ? valueType.GetGenericArguments()[0]
                                        : valueType.GetElementType();
                if (valueElemType.IsPrimitive || valueElemType == typeof(string))
                {
                    var enumerable = properties[key] as IEnumerable;
                    properties[key] = string.Join(separator, enumerable.Cast<object>());
                }
            }

            // Concat all key/value pairs into a string separated by ampersand
            return string.Join("&", properties
                .Select(x => string.Concat(
                    Uri.EscapeDataString(x.Key), "=",
                    Uri.EscapeDataString(x.Value.ToString()))));
        }
