How to reduce too many parameters from constructor

Question

I used 9 parameters in the constructor in a command service class, but sonarqube shows an error for too many parameters. Can anyone suggest a solution or design pattern solve this issue?

public CustomerCommandService(A a, B b, C c, D d, E e, F f, G g, H h, I i){
//some code here
}

Answer 1

Have you considered using a Struct to contain your different Params and then passing this structure to your constructor

public struct CustomerParams
{
    A a;
    B b;
    ...
}
public CustomerCommandService(CustomerParams cp)
{

}
