在C＃中使用反射

Question

Following this answer, I'm trying to replicate it and iterate over my CustomerModel properties.

CustomerModel pippo = new CustomerModel();
Type customer = pippo.GetType();
FieldInfo[] fields = customer.GetFields(BindingFlags.Public | BindingFlags.Instance);

When using the debugger, fields always has a count = 0 but CustomerModel has a lot of public properties I'd like to see in fields. How can I do that? Here's an extract of some properties declared I'd like to see.

    [DataMember]
    public String Id { get; set; }

    [DataMember]
    public String LoginName { get; set; }

    [DataMember]
    public String Password { get; set; }

    [DataMember]
    public String CreationDate { get; set; }

Perhaps the binding flags are incorrect? I'm new to the use of reflection.

Answer 1

Those are properties, not fields. Use GetProperties instead of GetFields .

In C#:

public class Foo {

    // this is a field:
    private string _name;

    // this is a property:
    public string Name { get; set; }

    // this is also a property:
    public string SomethingElse { get { return _name; } set { _name = value; } }

}

As Joe correctly pointed out the members in question are properties not fields. These are auto-implemented properties and the compiler will generate backing fields for them. However these fields won't be public hence the GetFields call fails because it is looking for the public members only. If you want to see the generated fields then change the code to the following

FieldInfo[] fields = customer.GetFields(BindingFlags.NonPublic | BindingFlags.Instance);
