Overloaded constructor in c#

Yes, you can do this using the base keyword:

class Parent
{
      public Parent(string s)
      {
         // code 
      }

     public Parent()
     {
        // code
     }
}

class Child :Parent
{
     public Child(string s) : base()
     {
         // code
     }

    public Child() : base("Hello")
    {
        // parent
    }

}

Here, the Child class's constructors force calls to specific overloads of the Parent class's constructors.
