“服务器”称由于在Get Method中的保护级别而未声明

Question

我在“服务器”上收到一条错误消息，说由于其保护级别未声明它。基本上，我试图运行Get方法来检索与订单号相关的文档。一切都作为Sharepoint对象进入，并序列化为XML。我正在尝试制作XML文件，将其复制到项目中的文件夹中，但出现了错误。我应该把这个命令放在其他地方吗？

<Route("orders/{id}/contents")>
<HttpGet>
Public Shared Function GetContents(ByVal id As String) As SPFolderOver
    Dim x As New SPFolderDB
    Dim retValue As ReturnVal = x.GetOrderInformation(id)
    Dim ex As Sharepoint = New Sharepoint()
    Dim t = ex.GetOrderContent(retValue.Year, retValue.SONumber)
    Dim myT = New SPFolderOver()
    myT = SPFolderOver.LoadFolder(t)
    SerializeObjectToFile(myT, Server.MapPath("~\XML\Works.xml"))
    Dim Path As String = "C:\Users\apearson\Documents\Visual Studio 2012\Projects\eDocs_API\XML\Works.xml"
    Return myT
End Function
