First, you cant declare a private virtual method .
But it is possible to override protected virtual methods.

Hi Arun,

We can not even declare private virtual method, We can't use the virtual modifier with the static, abstract, private or override modifiers.

Overriding of private virtual methods is not possible because the private methods in the inherited class can't be accessed.

If we use it:

public class Demo
{
private virtual void DemoMethod() { }
}
public class Demo2 : Demo
{
private override void DemoMethod() { }
}

It will screen Error

Correct Method:

public class Demo{
public virtual void DemoMethod() { }
}
public class Demo2 : Demo
{
public override void DemoMethod() { }
}

Hi Arun,

You can't declare private virtual methods because private access specifier does not allow to inherit the private member of a class in a derived class.
for example,
using System;
public class ABC
{
private virtual void mm() { }
}
public class abc:ABC
{
private override void mm()
{
Console.WriteLine("Hello");
}
}
class d:abc
{
public static void Main()
{
d D=new d();
D.mm();
}
}

Error:
------ 'ABC.mm()' : virtual or abstract members cannot be private 'abc.mm()' : virtual or abstract members cannot be private

But you can override protected virtual methods.

Hi Arun,

No, moreover, you cannot access private methods in inherited classes,They have to be protected in the base class to allow any sort of access.

No, because virtual methods cannot be private in the first place.
