Too many parameters (ARCH703)

Key dotnet.codequality.too-many-parameters · Severity info · Category codequality · Principle Kiss

A long parameter list makes calls hard to read and error-prone. Related data should be grouped into a single object.

Incorrect

public void CreateUser(string firstName, string lastName, string email,
    string phone, string address, string city, string country, int age)
{
    // ...
}

Correct

public void CreateUser(CreateUserRequest request)
{
    // ...
}

public record CreateUserRequest(string FirstName, string LastName,
    string Email, string Phone, Address Address, int Age);

Fix

Bundle related parameters into a meaningful parameter object (record/class).
