How do I make a variable of type C# class?

I am trying to create a class whose constructor includes a variable of type C# class. Are there any packages/keywords/etc. that can allow me to do that? For my specific instance, simply declaring the variable of type will not work.

I think what you are asking is how to create a constructor for a class that allows you to initialize a variable of some other type.

// the class with the parameterized constructor..
public class HasConstructor
{
  private ParameterType variable;

  public HasConstructor(ParameterType parameter)
  {
    variable = parameter;
  }
}

// the class you want to pass into the above...
public class ParameterType
{
}

// to create an instance of the first class...
new HasConstructor(new ParameterType());

Since I’m not really sure exactly what you are asking, though, I can’t really be sure this is the answer to your question.
