添加到我的答案.@H_301_4@

我已将我的返回值声明为String：@H_301_4@

<WebInvoke(UriTemplate:="member/login",Method:="POST",responseformat:=WebMessageFormat.Json,BodyStyle:=WebMessageBodyStyle.Bare)>
Public Function Create(data As IO.Stream) As String

        Dim strData As String = New IO.StreamReader(data).ReadToEnd()
        Dim UserAccessForm As LoginAccess = Me.getAnswer(strData)
        Dim jsonAnswer As String
        jsonAnswer = Newtonsoft.Json.JsonConvert.SerializeObject(UserAccessForm,Newtonsoft.Json.Formatting.None)
        Return jsonAnswer
End Function

所以不要回答这个问题：@H_301_4@

{"logged":false,"userID":"0","message":"Empty body"}

我明白了：@H_301_4@

<string xmlns="http://schemas.microsoft.com/2003/10/Serialization/">
{"logged":false,"message":"Empty body"}
</string>

有什么方法可以避免我的字符串答案的这种不必要的序列化？@H_301_4@
