推荐答案

添加一个包含所有枚举的类（如果有的话）



添加枚举如下：

Add a class which hold all your enumerations (if more)

Add enum as below:

public enum Gender
   {
       male = 1,
       female = 2,
       transgender = 3
   }

在C＃代码中，将其绑定如下：

In C# code, bind it as below:

foreach (var gen in typeof(Gender).GetFields())
            {
                if (gen.FieldType == typeof(Gender))
                    DropDownList1.Items.Add(new ListItem { Text = gen.Name, Value = gen.GetRawConstantValue().ToString() });
            }

谢谢，

在控制器中

In Controller

     List<selectlistitem> items = new List<selectlistitem>();

     items.Add(new SelectListItem { Text = "India", Value = "0",Selected = true});

     items.Add(new SelectListItem { Text = "Nepal", Value = "1" });

   

     ViewBag.Country = items;

     return View();

 }
</selectlistitem></selectlistitem>
