将值“ AAAAAAAAB9c =”转换为“ System.Version”类型时出错。 路径“版本”

Question

Whenever I try to access my Azure Mobile Service table, I get the following error:

An exception of type 'Newtonsoft.Json.JsonSerializationException' occurred in mscorlib.ni.dll but was not handled in user code

Additional information: Error converting value "AAAAAAAAB9k=" to type 'System.Version'. Path 'version', line 19, position 27.

This is the line where this error occurred:

await App.MobileService.GetTable<TodoItem>().InsertAsync(todoItem);

I don't actually need the version value in my table. This value is automatically generated by Azure. Is there a way to force ignore the version value?

This is the TodoItem definition:

 public class TodoItem
    {
    public string Id { get; set; }
    public DateTime createdAt { get; set; }
    public DateTime updatedAt { get; set; }
    public Version version { get; set; }
    public bool deleted { get; set; }

    ... and so on...
}

Answer 1

Your TodoItem code is wrong. It should be something like:

[Version]
public string Version {get; set;}

Here [Version] references VersionAttrbute that is located in the Microsoft.WindowsAzure.MobileServices namespace.

Answer 2

I would avoid using System.Version for this purpose. System.Version is for numeric version values such as software releases that following this pattern: wxyz . It looks like you are receiving a string that can't fit that, nor do I expect you to.
