ServiceStack - 返回类时清空json

Question

在将类连接到JSON时，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" )

              For x As Integer = 0 To 5

                     Dim newUserRow As DataRow = dt.NewRow()
                    newUserRow( "username" ) = "username-" & x & ""
                    newUserRow( "fullname" ) = "fullname-" & x & ""
                    dt.Rows.Add(newUserRow)

默认情况下，ServiceStack只会在您的DTO中序列化公共属性，而不是公共字段。因此，您需要在username类中将fullname和property各自声明为User，或者将ServiceStack.Text配置为序列化字段（通过设置JsConfig.IncludePublicFields真实的。）

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通过ServiceStack在这些方式上有所不同。
