What will happen if I give private constructor in a class?

Question

Manas Mohapatra · Answer

When you declare a private constructor you can't create instance of class. Have a look below code: public TestClass { private TestClass() { // Your logic } } // Creating object of TestClass TestClass obj = new TestClass(); // Throw you compilation error. So it helps to implement singleton design pattern.

Private Constructor Private constructor is a special instance constructor used in a class that contains static member only. If a class has one or more private constructor and no public constructor then other classes is not allowed to create instance of this class this mean we can neither create the object of the class nor it can be inherit by other class. The main purpose of creating private constructor is used to restrict the class from being instantiated when it contains every member as static. http://www.aspdotnet-suresh.com/2013/09/csharp-private-constructor-with-example.html
