Question
Monday, December 3, 2018 8:14 PM
I am using this .Net reflection TypeBuilder class to generate a class instance at runtime.
I am using .Net reflections to create list of objects with dynamic set of properties since I am reading input from excel file which may have dynamic columns as per the business requirement. But I am doing lot of loops to get the GetType().GetProperty("") which is reducing the performance. I am trying to delegate it dynamically for the PropertiesInfo[] which I get from the GetType().GetProperties().
Below is a static getter and setter delegate for Property1 of the runtime class create
Action<MyClass, int> setter = (Action<MyClass, int>)Delegate.CreateDelegate(typeof(Action<MyClass, int>), null, typeof(MyClass).GetProperty("Property1").GetSetMethod());
I would like to make this dynamic for each property created of my class. I'm stuck and not sure whether I can use any Linq MemberExpression to achieve it.
Can anyone help me out? That would be great.

Hi Harihara Krishnan ,
Thank you for posting here.
For your question, I made the following code.
1. I got all the properties in the class through PropertyInfo and stored them in an array.
2. I use a foreach loop to iterate through the properties in the array, and a property creates a delegate.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Reflection;
using System.Text;
using System.Threading.Tasks;
namespace test1
{
public class MyClass
{
private string name;
public string Name
{
get
{
return name;
}
set
{
name = value;
}
}
public string ID
{
get
{
return id;
}
set
{
id = value;
}
}
private string id;
}
class Program
{
static void Main(string[] args)
{
Type t = typeof(MyClass);
PropertyInfo[] properties = t.GetProperties();
foreach (var item in properties)
{
Action<string> setter = (Action<string>)Delegate.CreateDelegate(typeof(Action<string>), null, typeof(MyClass).GetProperty(item.Name).GetSetMethod());
}
Console.ReadKey();
}
}
}
Best regards,
Jack J Jun.
