ASP.NET MVC 4模型綁定問題

Question

問題是，模型綁定不綁定ViewModel的其中一個屬性。

我有一個ViewMode，HomeIndexViewModel。 其中一個屬性，ExcludeClientsWithoutAddress未在控制器中綁定。

的Fiddler顯示GET請求本身（無ExcludeClientsWithoutAddress）

GET /主頁/ searchByClient？分貝= dev的& fileNumber = &的firstName = XXX & includeContacts =真HTTP/1.1

對於某些原因，其他屬性（FileNumber，FirstName，LastName，IncludeContacts和File）正確綁定。

缺少什麼我在這裏？

namespace CertifiedMail.Web.Mvc4.OneOffs.Models 
{ 
    public class HomeIndexViewModel 
    { 
     [DisplayName("File #")] 
     public string FileNumber { get; set; } 

     [DisplayName("First Name")] 
     public string FirstName { get; set; } 

     [DisplayName("Last Name")] 
     public string LastName { get; set; } 

     [DisplayName("Include Contact")] 
     public bool IncludeContacts { get; set; } 

     [DisplayName("Exclude Clients Without Address")] 
     public bool ExcludeClientsWithoutAddress { get; set; } 

     public HttpPostedFileBase File { get; set; } 
    } 
} 

在控制器，

[System.Web.Mvc.HttpGet] 
public string SearchByClient([FromUri]HomeIndexViewModel model) 
{ 
    IEnumerable<SearchResult> searchResults = new List<SearchResult>(); 

    SearchByArgs args = BuildSearchByArg(model); 

    if (string.IsNullOrWhiteSpace(model.FileNumber)) 
    { 
     if (!string.IsNullOrWhiteSpace(model.FirstName) || !string.IsNullOrWhiteSpace(model.LastName)) 
      searchResults = ClientSearchDataAccess.SearchByClientName(args); 
    } 
    else 
     searchResults = ClientSearchDataAccess.SearchByClientNumber(args); 

    return JsonConverter.SerializeSearchResults(searchResults); 
} 

這裏是觀。

<div class="col-sm-5 searchPanel"> 
    <div class="panel panel-default glowGridPanel"> 
     <div class="panel-body searchPanelBody"> 
      <div class="row">

您的Fiddler請求顯示從瀏覽器發出的內容。它不會發送您的ExcludeClientsWithoutAddress屬性。

由於此屬性未標記爲可空bool?它在綁定中被分配一個默認值。

您有這些輸入爲ng_model，這表明您的Angular代碼沒有發送該字段。
