The issue is that, model binding doesn't bind one of the properties of ViewModel.
问题是，模型绑定没有绑定ViewModel的一个属性。
I have a ViewMode, HomeIndexViewModel. One of the properties, ExcludeClientsWithoutAddress doesn't get bound in controller.
我有一个ViewMode HomeIndexViewModel。其中一个属性，exclusive declientswithoutaddress在控制器中不会被绑定。
Fiddler shows GET request as such (without ExcludeClientsWithoutAddress)
Fiddler显示GET请求是这样的(没有排除不带地址的declientswithoutaddress)
GET /Home/searchByClient?db=dev&fileNumber=&firstName=xxx&includeContacts=true HTTP/1.1
获得/ Home / searchByClient吗?db = dev&fileNumber = firstname = xxx&includeContacts HTTP / 1.1 = true
For some reason, Other properties (FileNumber, FirstName, LastName, IncludeContacts, and File) get bound correctly.
由于某些原因，其他属性(FileNumber、FirstName、LastName、IncludeContacts和File)被正确绑定。
What am I missing here?
我错过了什么?
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; }
}
}
Within Controller,
在控制器中,
[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);
}
Here is the View.
这是视图。

Your Fiddler request shows what is emitted from the browser. It isn't sending your ExcludeClientsWithoutAddress property.
Fiddler请求显示从浏览器发出的内容。它不会发送你的专有地址。
Since this property is not marked nullable bool? it is being assigned a default value in binding.
既然这个属性没有被标记为可空bool?它被赋值为绑定的默认值。
You have these inputs as ng_model which suggests your Angular code is not sending this field.
您将这些输入作为ng_model，这表明您的角代码不会发送这个字段。
