Dropdownlist绑定到一个枚举

我使用的是asp.net mvc。这可能是一个直截了当的。我结合我的下拉列表，枚举如下Dropdownlist绑定到一个枚举

@Html.DropDownListFor(m => m.IndicatorGroups, Model.IndicatorGroups.ToSelectList(), new { @id = "ddlIndicatorGroup" })

型号定义如下

public class SearchControlViewModel 
{ 
    ... 
    public GlobalEnums.IndicatorGroup IndicatorGroups { get; set; } 
    ... 

}

ToSelectList函数的定义如下

public static SelectList ToSelectList<TEnum>(this TEnum enumObj) where TEnum : struct, IComparable, IFormattable, IConvertible 
    { 
     var values = from TEnum e in Enum.GetValues(typeof(TEnum)) 
        select new { Id = Convert.ToInt32(e), Name = e.ToString() }; 
     return new SelectList(values, "Id", "Name", enumObj); 
    }

现在我已经添加了值的空格来枚举，我想显示这些值而不是“值与联合国derscores“

public enum IndicatorGroup 
    { 
     [EnumMember(Value = "Include ANY MatchingIndicator")] 
     Include_ANY_MatchingIndicator = 1, 
     [EnumMember(Value = "Include ALL MatchingIndicator")] 
     Include_ALL_MatchingIndicator, 
     [EnumMember(Value = "Exclude ANY MatchingIndicator")] 
     Exclude_ANY_MatchingIndicator, 
     [EnumMember(Value = "Exclude ALL MatchingIndicator")] 
     Exclude_ALL_MatchingIndicator 
    };

我该如何做到这一点？

在'MVC-5'，用['EnumDropDownListFor']（https://msdn.microsoft.com/en-us/library/system.web.mvc.html.selectextensions.enumdropdownlistfor%28v= vs.118％29.aspx）直接绑定enum到dropdownlist。 – mmushtaq

请参阅[这个答案]（https://stackoverflow.com/questions/388483/how-do-you-create-a-dropdownlist-from-an-enum-in-asp-net-mvc）（使用'DescriptionAttribute '） –

由于我的要求是很简单的，所以我替换字符串。我觉得必须有更好的方式来做同样的事情。

public static SelectList ToSelectList<TEnum>(this TEnum enumObj) where TEnum : struct, IComparable, IFormattable, IConvertible 
{ 
    var values = from TEnum e in Enum.GetValues(typeof(TEnum)) 
       select new { Id = Convert.ToInt32(e), Name = e.ToString().Replace('_', ' ') }; 
    return new SelectList(values, "Id", "Name", enumObj); 
}

在MVC中，我们有EnumDropDownListFor，我们可以直接与我们的任何枚举绑定，这是非常相似的DropDownListFor

样品前：

public enum Courses 
{ 
    [Display(Name = "ASP.NET")] 
    ASPNet, 
    [Display(Name = "C# .NET")] 
    CSharp, 
    [Display(Name = "Java")] 
    Java, 
    [Display(Name = "Objective C")] 
    ObjectiveC, 

}

型号：

public class Student 
{ 
    [Key] 
    public String StudentId { get; set; } 

    [Display(Name="Student Name")] 
    public String Student { get; set; } 

    [Display(Name = "Languages")] 
    public Courses Language { get; set; } 


}

在视图中：

<div class="form-group"> 
    @Html.LabelFor(model => model.Languages, htmlAttributes: new { @class = "control-label col-md-2" }) 
    <div class="col-md-10"> 
     @Html.EnumDropDownListFor(model => model.Languages, htmlAttributes: new { @class = "form-control" }) 
     @Html.ValidationMessageFor(model => model.Languages, "", new { @class = "text-danger" }) 
    </div> 
</div>
