A question was asked about “the difference between Variable and Property”. In response to Mr. Patel’s answer. I pose a follow up question. “ Why am I allowed to make a change to the variable’s value, without invoking the property, when the Varible is still declared as Private?. The modified problem is listed below.

using System;
namespace Advanced_
{
class TestClass
{
private string x = “Test Test”;
void TestFun()
{
Console.WriteLine(x);
}

 public string ChangeName
 {
 get { return x; }
 set { x = value; }
 }
 // Application Execution begins Here! 
 static void Main(string[] args)
 {
 // Class instantiation / Objection creation begins
 TestClass obj = new TestClass();
 // First Method Call/ Invocation to Object 'TestFun' with original string value
        obj.TestFun();
 // Second Method Call/ Invocation to Object 'TestFun' with modified string value
 // Note Property is not called.
            obj.x = "Test Failure";
            obj.TestFun();
 //obj.ChangeName = "Property Testing ";
 }
