c# - 如何更改类别/商品名称？

例如：

public class Car{

     public string color {get; set;}

     public int VINCode {get;set;}

}

现在，如果我呼叫nameof(Car)，它将返回“ Car”

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

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

     public int VINCode {get;set;}

}

但是如何获取nameof以返回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];

为此修复：

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

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

此序列化：

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

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

将会：

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

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

最佳答案

恐怕您不能使用nameof来做到这一点。

但是，如果要获取CustomAttribute的值，可以尝试以下操作：

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

那么你也能

// 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;
