In Asp.net C# Is that possible to declare a variable as a pu

In Asp.net C# Is that possible to declare a variable as a public inside a method ?

Example:when i declare variable like below:

public void employee()

{

public int employeeNo;

}

Am getting the many compile time errors.

But When i google it,I got an information like , when a scope term is Public, used with Variables/Properties/Methods/Types then it will visible inside or outside of the project

So Am in bit confusion why it is giving error, It will be very helpful,if you clarify this.

Thanks
