ServiceStack - 返回类时清空json

Question

当将类连接到JSON时,我对ServiceStack有一个非常奇怪的问题 - 对象是空的,但XML工作正常.

发现一些建议,JSON序列化程序仅在属性公开时起作用,但正如您在下面看到的,我的属性是公共的.

请参阅下面的代码和截图.任何建议都非常感谢.

             _users = GetUsersTest(_users)
              Return _users

        End Function

        Public Function GetUsersTest(_users As List (Of User)) As List ( Of User )

              Dim dt As New DataTable
             dt.Columns.Add( "username" )
             dt.Columns.Add( "fullname" )

                    newUserRow( "username" ) = "username-" & x & ""

默认情况下,ServiceStack只会序列化DTO中的公共属性,而不是公共字段.所以,你需要任何声明username,并fullname各自为property您的User类,或配置ServiceStack.Text序列化的字段(通过设置JsConfig.IncludePublicFields为True).

请注意,对于JSON序列化,使用ServiceStack.Text,而对于XML序列化,则使用BCL XML序列化程序.因此,XML与JSON序列化的配置和行为可以在ServiceStack的这些方式上有所不同.
