C#利用反射给Model 的可空字段赋值

Main

public static void Main(string[] args)
        {
            var list = new List<string>();
            list.Add("1");
            list.Add("Tom");
            list.Add("");
            list.Add("1234@sss");

            var model = new TestModel();

            var properties = model.GetType().GetProperties();

            for (int i = 0; i < properties.Count(); i++)
            {
                var type = properties[i].PropertyType;

                if (type.IsGenericType && type.GetGenericTypeDefinition() ==  typeof(Nullable<>))
                {
                    if (string.IsNullOrEmpty(list[i]))
                    {
                        properties[i].SetValue(model, null, null);
                        continue;
                    }
                    type = Nullable.GetUnderlyingType(type);
                }

                properties[i].SetValue(model, Convert.ChangeType(list[i], type), null);
            }

            Console.ReadKey();
        }

Model

    public class TestModel
    {
        public int No { get; set; }

        public string Name { get; set; }

        public int? Age { get; set; }

        public string Email { get; set; }
    }
