Object created from the class "object" does not allow to retrieve property values

I have an object created from the class "object" and it contains a list I have created. The list is a collection of objects created from a class called "MyClass". And, that class contains two string properties.

public Class MyClass 
{
    private string _propOne;
    public string PropOne
    {
       get {return _propOne;}
       set {_propOne=Value;}
    }

    private string _propTwo;
    public string PropTwo
    {
       get {return _propTwo;}
       set {_propTwo=Value;}
    }
}

I have a method which returns an object of the class "object"

private object GetData() 
{
    // It converts the list created to an object created from the class "object"
}

Then I call the method like in the following.

object temp=GetData();

Now I want to iterate over "temp" and assign it to another list created from the objects of the class "MyClass".

private List<MyClass> _anotherCollection;
public List<MyClass> AnotherCollection
{
   get {return _anotherCollection;}
   set {_anotherCollection=Value;}
}

........................

foreach (var a in temp.GetType().GetProperties())
{
   object firstParam = "PropOne";
   object secondParam = "PropTwo";
   AnotherCollection.Add(new MyClass() { PropOne = a.GetValue(firstParam), PropTwo = a.GetValue(PropTwo) });
}

But it gives me the following compilation error.

Cannot implicitly convert type 'object' to 'string'. An explicit conversion exists (are you missing a cast?)

Can someone help me to fix it ?

You have to cast the returned object from GetValue to a string. The compiler doesn't know that the object returned from GetValue is actually a string, so you have to tell it that like this.

Also, you have to pass in the instance you are trying to get the value for (temp in this case):

PropOne = (string)a.GetValue(temp)
