how to get both fields and properties in single call via reflection?

Question

I apologize if this is covered somewhere. I did research before posting!

okay, so question...I\'m using GetType( ).GetProperties, but it isn\'t returning simple inst

To get either properties or fields, you can say:

var q=
    from it in type.GetMembers(bindingAttr)
    where it is PropertyInfo||it is FieldInfo
    select it;

where bindingAttr could be

var bindingAttr=
        BindingFlags.NonPublic|
        BindingFlags.Public|
        BindingFlags.Instance;

Remove BindingFlags.NonPublic if you don't want to get non-public members. By the way, the query is not a single call but a single statement.

To get the value of either a property or a field without casting it by yourself, use InvokeMember for the trick:

static object GetValue(
        T x, object target) where T:MemberInfo {
    var invokeAttr=(
            x is FieldInfo
                ?BindingFlags.GetField
                :x is PropertyInfo
                    ?BindingFlags.GetProperty
                    :BindingFlags.Default)|
            BindingFlags.NonPublic|
            BindingFlags.Public|
            BindingFlags.Instance;

    return target.GetType().InvokeMember(
        x.Name, invokeAttr, default(Binder), target, null);
}

Similarly, to set the value:

static void SetValue(
        T x, object target, object value) where T:MemberInfo {
    var args=new object[] { value };
    var invokeAttr=(
            x is FieldInfo
                ?BindingFlags.SetField
                :x is PropertyInfo
                    ?BindingFlags.SetProperty
                    :BindingFlags.Default)|
            BindingFlags.NonPublic|
            BindingFlags.Public|
            BindingFlags.Instance;

    target.GetType().InvokeMember(
        x.Name, invokeAttr, default(Binder), target, args);
}

It will throw if you pass a MemberInfo other than PropertyInfo or FieldInfo as the first argument, because BindingFlags.Default doesn't specify what you are going to do.
