ServiceStack - 返回類時的空JSON

Question

當將一個類序列化爲JSON時，ServiceStack中存在一個非常奇怪的問題 - 對象爲空，但是XML工作正常。

發現了一些建議，JSON序列化程序只在屬性公開時才起作用，但正如您在下面看到的，我的屬性是公開的。

請參閱下面的代碼和截圖。任何建議都非常感謝。

       For x As Integer = 0 To 5 

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

默認情況下，ServiceStack只會序列化的公共性能，不公開領域，在你的DTO。因此，您需要在User類中聲明username和fullname各爲property，或者將ServiceStack.Text配置爲序列化字段（將JsConfig.IncludePublicFields設置爲True）。

請注意，對於JSON序列化，使用ServiceStack.Text，而對於XML序列化，使用BCL XML序列化程序。因此，使用ServiceStack以XML和JSON序列化的配置和行爲可以以這些方式不同。
