c# - 如何更改类/属性名称？

Question

例如:

public class Car{

     public string color {get; set;}

     public int VINCode {get;set;}

}

现在，如果我调用 nameof(Car)，它会返回“Car”

[Name("something")]
public class Car{

     [Name("something_else")]
     public string color {get; set;}

     public int VINCode {get;set;}

}

但是如何让 nameof 返回 Name 属性中的值而不是类或方法的名称。例如:nameof(Car) == "something" 或 nameof(Car.color) == "something_else"。

问题:

var modelState = JsonConvert.DeserializeObject<Dictionary<string, List<string>>>(data);

        var departmentViewModels = modelState[nameof(DepartmentListView.DepartmentsViewModels)][0];
        var departmentTypes = modelState[nameof(DepartmentListView.DepartmentsViewModels)][0];

修复:

var modelState = JsonConvert.DeserializeObject<DepartmentListView>(data);

        var departmentViewModels = modelState.DepartmentsViewModels;
        var departmentTypes = modelState.DepartmentTypes;

这个的序列化:

public class DepartmentListView
    {
        public IEnumerable<DepartmentViewModel> DepartmentsViewModels { get; set; }

        public IEnumerable<DepartmentType> DepartmentTypes { get; set; }
    }

将是:

departmentsViewModel : [], departmentTypes : [] (with lowercase)

我知道我可以使用 JsonProperty 更改小写序列化，但我认为我可以更改类或属性的名称...

Answer 1

恐怕你不能用 nameof 来做。

但是如果你想获得 CustomAttribute 的值，你可以试试这个:

// I assume this is your Name class
public class Name: Attribute
{
    public string Data { get; }
    public Name(string data) { Data = data; }
}

那么你可以

// Will return "something"
var classAttrData = ((Name) typeof(Car).GetCustomAttribute(typeof(Name))).Data;

// Will return "something_else"
var fieldAttrData = ((Name) typeof(Car).GetField(nameof(Car.color)).GetCustomAttribute(typeof(Name))).Data;
