Get value of value of variable C#

Sample scenario:

public class MyClass
{
string sample1 = "Hello";
string sample2 ="sample1"
}

Console.WriteLine(sample);
//This should write 'Hello' in console.

The actual scenario is as follows :

public class Sample1
{
string variable1=1;
}
public class Sample2
{
Sample1 sample;
}


public class Access
{
public void getData(Sample2 s)
{
string return="s.sample.variable1"
Console.Writeline(return)
//This should return '1'(value of 's.sample.variable1')
}

I have tried my level best to understand the concept of reflection and also some sample code available in other similar posts, but nothing worked.
