@Html.DropDownListForm=>m.YourProperty，Model.YourSelectList，new{data\u live\u search=true，data\u width=100%，data\u toggle=tooltip，title=Select}使用下划线，而不是连字符这项工作，谢谢Stephen这与OP的问题有什么关系？你想问一个新问题吗？

public ActionResult Contact()
{
    Contact homeViewModel = new Contact();
    homeViewModel.subject = new List<Subject>();
    homeViewModel.subject.Add(new Subject { Id = 1, subject1 = "General Customer Service" });
    homeViewModel.subject.Add(new Subject { Id = 2, subject1 = "Suggestions" });
    homeViewModel.subject.Add(new Subject { Id = 3, subject1 = "Product Support" });

    homeViewModel.Selectedid = 1; //this sets the default value for your dropdown

    return View(homeViewModel);
}

public class Contact
{   
  [Required(ErrorMessage="Please fill the following")]
  public string name { get; set; }
  [Required(ErrorMessage = "Please Enter Correct Username")]
  [RegularExpression(@"^([0-9a-zA-Z]([\+\-_\.][0-9a-zA-Z]+)*)+@(([0-9a-zA-Z][-\w]*[0-9a-zA-Z]*\.)+[a-zA-Z0-9]{2,3})$", ErrorMessage = "Please provide valid email id")]
  public string email { get; set; }
  public List<Subject> subject { get; set; }
  [Required(ErrorMessage="Please fill the following")]
  public string message { get; set; }
  public int Selectedid { get; set; }
}

 @model programname.model.Contact

 @Html.DropDownList("Selectedid", new SelectList(Model.subject, "Id",    "subject1", Model.Selectedid), new { @class = "form-control", id = "subject", required = "required" }
