绑定泛型列表里面enity

Question

实体这是模型我有我使用LINQ

public class Physician 
{ 
    public Physician() 
    { 
     PhysicianAddress = new Address(); 
    }  
    public int PhysicianId { get; set; } 
    public string NPI { get; set; } 
    public string PhysicianPrefixName { get; set; } 
    public string PhysicianFirstName { get; set; }   
    public string PhysicianMiddleName { get; set; }   
    public string PhysicianLastName { get; set; }   
    public string PhysicianPhoneExt { get; set; }   
    public string PhysicianPhoneNum { get; set; }   
    public string PhysicianFaxNum { get; set; }   
    public string PhysicianEmailAddr { get; set; }   
    public string PhysicianComment { get; set; }   
    public List<Site> PracticeLocationsList { get; set; }   
    public Address PhysicianAddress { get; set; }   
    public int? MergedIntoPhysicianId { get; set; } 
} 

我从StoredProcedure的获取数据，然后我绑定的返回结果模型

数据绑定到它

var physicians = (from sp in e.GetSitePhysicians((int)request.SiteId) 
           select new Physician() 
           { 
            PhysicianId = sp.PhysicianId, 
            PhysicianFirstName = sp.PhysicianFirstName, 
            PhysicianMiddleName = sp.PhysicianMiddleName, 
            PhysicianLastName = sp.PhysicianLastName, 
            NPI = sp.NPI, 
            PhysicianPhoneNum = sp.PhysicianPhoneNum, 
            PhysicianFaxNum = sp.PhysicianFaxNum, 
            PhysicianEndDate = sp.PhysicianEndDate, 
            PhysicianEffectiveDate = sp.PhysicianEffectiveDate, 
            PhysicianComment = sp.PhysicianComment, 
            AddressId = sp.AddressId, 
            PhysicianEmailAddr = sp.PhysicianEmailAddr, 
            PhysicianPhoneExt = sp.PhysicianPhoneExt, 
            PhysicianAddress = new Address() 
            { 
             SiteAddressId = sp.SiteAddressId ?? 0, 
             Street1 = sp.SiteAddressStreet1 ?? string.Empty, 
             Street2 = sp.SiteAddressStreet2 ?? string.Empty, 
             City = sp.SiteAddressCityName ?? string.Empty, 
             PostalCode = sp.SiteAddressPostalCode ?? string.Empty, 
             State = sp.GeographicalStateProvinceCode ?? string.Empty, 
             ParkingInstructions = sp.SiteAddressParkingInstructions ?? string.Empty, 
            }, 
            PracticeLocationsList=new Site() 
              { 
               Id = sp.SiteId, 
               Name = sp.SiteName, 
               SiteMainPhoneNum = sp.SiteMainPhoneNum, 
               Address = new Address 
               { 
                SiteAddressId = sp.SiteAddressId??0, 
                Street1 = sp.SiteAddressStreet1, 
                Street2 = sp.SiteAddressStreet2, 
                City = sp.SiteAddressCityName, 
                PostalCode = sp.SiteAddressPostalCode, 
                State = sp.GeographicalStateProvinceCode 
               }, 
               Contacts = new List<SiteContact>() { new SiteContact() } 
              } 
           }).ToList(); 

当我尝试绑定我的网站对象到PracticeLocationsList它会产生编译时错误，“不能隐式转换类型'网站'为'System.Collections.Generic.List'”。

如何将我的网站对象转换为列表，然后绑定？

Answer 1

因为您试图将一个对象分配给列表。

试试这个：

PracticeLocationsList = new List<Site> { new Site()... 

Answer 2

假设PracticeLocationsList可以被分配到一个List<Site>，你看这个：

PracticeLocationsList= new List<Site>() 
            { new Site() 
             { 
              Id = sp.SiteId, 
              Name = sp.SiteName, 
              SiteMainPhoneNum = sp.SiteMainPhoneNum, 
              Address = new Address 
              { 
               SiteAddressId = sp.SiteAddressId??0, 
               Street1 = sp.SiteAddressStreet1, 
               Street2 = sp.SiteAddressStreet2, 
               City = sp.SiteAddressCityName, 
               PostalCode = sp.SiteAddressPostalCode, 
               State = sp.GeographicalStateProvinceCode 
              }, 
              Contacts = new List<SiteContact>() { new SiteContact() } 
             } 
            }
