How can you retrieve the value of a specific field using Reflection?

1. GetValue with Type and FieldInfo

2. SetValue with BindingFlags

3. Invoke on Type object

4. GetFieldInfo and Retrieve

The correct answer is: GetValue with Type and FieldInfo

To retrieve the value of a specific field using Reflection, using the method provided in the first choice is the most effective approach. The method `GetValue` is invoked on an instance of a field. This is typically done after obtaining the `FieldInfo` object, which represents the specific field you want to access. The `FieldInfo` is derived from the type of the object and allows you to access metadata about the field, including its type, access modifiers, and more. Using `GetValue`, you can retrieve the value of the field from the object instance by passing the instance as an argument. This means you can effectively access fields dynamically at runtime, making Reflection a powerful tool for scenarios such as debugging, inspecting objects, or even implementing features like serialization and deserialization where the exact structure of the objects might not be known at compile time. The other choices do not address retrieving field values in the same direct manner. The second choice focuses on setting values rather than retrieving them, which deviates from the question's requirement. The third choice pertains to invoking methods on a type rather than accessing field values. Finally, the fourth choice mentions retrieving `FieldInfo`, but it doesn't specify the process for effectively getting the field's value from an instance,
