如何在MVC视图中循环使用DataAnnotation的DisplayName？

问题描述

我想访问 DataAnnotation 的 DisplayName 和类似的 GroupName 然后在MVC视图中循环。例如，让我说我的一个模型属性是这样的

I want to access DataAnnotation’s DisplayName and similar GroupName of a model class then loop through in MVC view. For Example let me say one of my model properties are like this

public class Person
{
    [Display(Name="Home Phone",GroupName="Home")]
    public string HomePhone { get; set; }
    [Display(Name = "Home Address", GroupName = "Home")]
    public string HomeAddress { get; set; }
    [Display(Name = "Office Phone", GroupName = "Office")]
    public string OfficePhone { get; set; }
    [Display(Name = "Office Address", GroupName = "Office")]
    public string OfficeAddress { get; set; }
}

如何循环浏览 DisplayName 其中类似的 GroupName ？

结果应该这样，

首页

1. 家庭电话


2. 家庭地址

Office

1. 办公电话


2. 办公地址

I found the solution.

public List<string> GetDisplayNamesGrouped(Type ClassName, string GroupName)
    {
        List<string> DisplayNameList = new List<string>();
        var properties = ClassName.GetProperties();
        foreach (var property in properties)
        {
            var displayAttribute = property.GetCustomAttributes(typeof(DisplayAttribute), true).FirstOrDefault() as DisplayAttribute;
            string displayName = property.Name;
            if (displayAttribute != null)
            {
                if (displayAttribute.GroupName == GroupName)
                {
                    displayName = displayAttribute.Name;
                    DisplayNameList.Add(displayName);
                }
            }
        }
        return DisplayNameList;
    }

用法：

var Home = GetDisplayNamesGrouped(typeof(Person), "Home");
var Office = GetDisplayNamesGrouped(typeof(Person), "Office");
