Json反序列化多个对象

Question

我遇到了反序列化对象的问题。

目前我有两个需要反序列化的对象，但我只能输入一个。我如何实现这一目标？

这是我的代码：

Public Function PostContract(ByVal data As String) As String Implements IEchoTest.PostContract
    Dim biz As New ContractBiz
    Dim response As New ContractModel.ContractResponse

    Dim request As String = data
    '[Convert to entity data and pass to Business Layer]
    response = biz.CreateContract(JsonConvert.DeserializeObject(Of Contract)(request))

    Return JsonConvert.SerializeObject(response)
End Function
