retrieve the instance of a class from the information contained in a MemberInfo in C#

Here is my case: I have a Class Main which has a field

Button button1 = new Button()

I have retrieved a MemberInfo from button1. I would now like to set its IsEnable property. After many fruitless searches I can't find the solution.

I want to do something like this Object obj = memberInfo.GetInstance();

I've tried this code:

Type type = currentForm.GetType(); // OK
FieldInfo field = type.GetField(member.Name); // OK


Control control = (Control)field.GetValue(member); // Not OK, control is Null
control.IsEnabled = false;

Thank you for your help!
