如何获取 C# 模型中的密钥？

Question

I want to have a loop where I can get every object key in my model.

I have this model:

public class RoleModel
{
    public int ID { get; set; }
    public string RoleName { get; set; }
    public UserRoleModel TrackAndTrace { get; set; }
    public UserRoleModel MailProcessing { get; set; }
}

I want to achieve something like:

for (var i = 0, len = Object.keys(RoleModel).length; i < len; i++) {

  Console.Writeline(Object.keys(RoleModel)[i])

}

which would return

ID
RoleName
TrackAndTrace 
MailProcessing 

Answer 1

So, you need a Reflection. Reflection is Virtual Machine API. You can use it for get metadata of class. Please see example:

PropertyInfo[] properties = typeof(RoleModel).GetProperties();
foreach (PropertyInfo property in properties)
{
    Console.Writeline(property.Name);
}

Answer 2

PropertyInfo[] properties = typeof(RoleModel).GetProperties();
foreach (PropertyInfo property in properties)
{
    Console.Writeline(property.Name);
}
