C# 使用不可变集合或减少字段“CreateContactMapping”的可访问性

Question

我在旧项目中的类遇到问题，我不知道如何重构这部分，我从 sonarcube 收到以下错误消息：

Use an immutable collection or reduce the accessibility of the field(s) 'CreateContactMapping'.Why is this an issue?

这是一段代码

Use an immutable collection or reduce the accessibility of the field(s) 'CreateContactMapping'.Why is this an issue?

如何最好地解决这个问题？

一种解决方案可能是更改Dictionary为，然后在初始化字典后ImmutableDictionary运行。.ToImmutableDictionary()

public static readonly ImmutableDictionary<string, Func<UpdateContactServiceRequest, object>> UpdateContactMapping =
    new Dictionary<string, Func<UpdateContactServiceRequest, object>>
    {
        { "firstname", req => req.FirstName },
        { "lastname", req => req.LastName },
        { "full_name", req => req.FullName },
        { "email", req => req.Email },
        { "phone", req => req.Phone },
        { "date_of_birth", req => req.BirthDate },
        { "job_title", req => req.JobTitle },
        { "occupation", req => req.Occupation },
        { "renda", req => req.MonthlyIncome },
        { "lifecyclestage", req => req.LifeCycleStage },
        { "hs_lead_status", req => req.LeadStatus },
        { "ali_email_validated", req => req.EmailValidated },
        { "ali_sms_token_validated", req => req.CellphoneValidated },
        { "id_da_proposta_atual", req => req.CurrentProposalId },
        { "contact_type", req => req.ContactType }
    }.ToImmutableDictionary();
