问题描述
这是我输入的DTO:
public class Individualinformation : IPerson
{
public string FirstName { get; set; }
public string LastName { get; set; }
public Address PrimaryAddress { get; set; }
public DateTime? DateOfBirth { get; set; }
public string CitizenShip { get; set; }
}
当用户尝试使用流利验证来更新名字和姓氏时,我想阻止它。
要做那件事我需要写什么规则?
解决方法
似乎您正在寻找不可变(只读)属性。这是一个示例:
public class IndividualInformation : IPerson
{
public string FirstName { get; }
public string LastName { get; }
public Address PrimaryAddress { get; set; }
public DateTime? DateOfBirth { get; set; }
public string CitizenShip { get; set; }
public IndividualInformation(string firstName,string lastName)
{
FirstName = firstName;
LastName = lastName;
}
}
var info = new IndividualInformation("Jane","Doe")
{
PrimaryAddress = ...
};
info.FirstName = "John"; // this will throw an error
如果启用了C#9,则可以为此使用init
属性:
public class IndividualInformation : IPerson
{
public string FirstName { get; init; }
public string LastName { get; init; }
public Address PrimaryAddress { get; set; }
public DateTime? DateOfBirth { get; set; }
public string CitizenShip { get; set; }
}
var info = new IndividualInformation
{
FirstName = "Jane",LastName = "Doe",PrimaryAddress = ...
};
info.FirstName = "John"; // this will throw an error
