解决方法
您最有可能拥有两次包含相同属性的模型。也许您正在使用ѭ1来隐藏基本属性。
解决方案是覆盖属性或使用其他名称。
如果您共享您的模型，我们将能够详细说明。
,我遇到了同样的问题，这就是我解决的方法。我的ViewModel中有一个同名的重复属性。一个属性位于BaseViewModel中，另一个属性位于派生模型中。
public class BaseviewModel{
public int UserId { get; set; }
}
public class Model : BaseViewModel
{
public int UserId { get; set; }
}
public class BaseviewModel{
public int UserId { get; set; }
}
public class Model : BaseViewModel
{
public int User_Id { get; set; }
}
public string PropertyName {get;set;} // actually set propertyName,get propertyName
public string propertyName {get;set;}
public string PropertyName {get;set;}
private string propertyName {get;set;}
public int LinkId {get;set;}
public int LinkID {get;set;}
Notes
notes
class Post {
public string notes { get; set; }
}
<input ng-model=\"post.Notes\" type=\"text\">
foreach
Dictionary<string,string>
foreach (var item in myObject)
{
myDictionary.Add(Convert.ToString(item.x),item.y);
}
item.x
IndexAttribute
[Index(IsUnique = true)]
public string Thing1 { get; set; }
