A private constructor is a special instance constructor. It is commonly used in classes that contain static members only. If a class has one or more private constructors and no public constructors, then other classes (except nested classes) are not allowed to create instances of this class.
For example:
public class Customer
{
private Customer()
{
}
public static string getCustomerName()
{
return "Hello World";
}
}
Access this getCustomerName() Function
class AccessCustomer
{
static void Main()
{
string a;
a = Customer.getCustomerName();
System.Console.WriteLine("Customer Private Constructor: {0}",a);
}
}
OUTPUT
Hello World
