I am trying to get the property value via a MemberExpression.
For example, given the following object, I want to get the Guid value in the "Id" property.
public class Employee
{
public Guid Id {get; set}
}
I have an event being called which has a MemberExpression passed to that event. The MemberExpression parameter represents the Employee.Id property. How can I get the VALUE of "Id" from the MemberExpression? The code I'm trying to use is as follows:
(MemberExpression employeeIdMember is parameter to the event)
if ((employeeIdMember.Member as PropertyInfo) != null)
{
PropertyInfo employeeIdProperty = employeeIdMember.Member as PropertyInfo;
// at this point employeeIdProperty represents {System.Guid Id}
PropertyInfo parentObject = (MemberExpression)employeeIdMember.Expression).Member as PropertyInfo;
// at this point, parentObject represents {BusinessObjects.Employee Employee}
// HOW to call employeeIdProperty.GetValue(parentObject) to get the Id Property Value?? I've tried this call here, but it does not work
}
at this point you have 2 properties to make you double indirection.
it miss a entry point : a reference to "BusinessObjects"
then call
var businessObjects = ???
var id = employeeIdProperty.GetValue(parentObject.GetValue(businessObjects));
