Setvalue for field value in reflection using C#

Question

Here is my scenario.
I have a MyClass class and protected field _myAttempt which is a list.

_myAttempt list class looks like below.

From MyClassTest, how can i assign value to Daily using Reflection.

I have tried following under MyClassTest using reflection but I am not able to assign object to SetValue.

Any help would be appreciated.

What I have tried:

internal class MyClass {
protected List<attempt> _myAttempt = null;
}

public class Attempt {
public string Daily {get;set;}
public string Weekly {get;set;}
}

public class MyClassTest {
[TestMethod]
public void TestDaily(){
var fieldInfo = typeof(MyClass).GetField("_myAttempt", BindingFlags.NonPublic |
BindingFlags.Instance);
fieldInfo.SetValue(obj,value); //not sure what is object here and how to assign

}
}

In your case obj is instance of MyClass and value is list you wish to pass.

C#

var obj = new MyClass();
var newValue = new List<attempt>();

fieldInfo.SetValue(obj, newValue );
