Question

我收到以下错误Class 'PropGenie_WebService.Branch' cannot be indexed because it has no default property.而且我不确定原因。我用谷歌搜索，但没有得到适当的解释或修复。 C＃help welcome。

我在branch.vb类中的代码：

Public Function Update() As Branch
    Return Update(Me, Path) 'error at update.
End Function

在我的Base类（Resources.vb）中，我有：

Public Shared Function Update(Of T As {Resources, New})(resource As T, path As String) As T
        Dim request = CreateRequest(path & "/{id}", Method.PATCH)
        request.AddUrlSegment("id", resource.Id.ToString(CultureInfo.InvariantCulture))
        request.AddBody(resource)
        Dim Client = CreateClient()
        Dim responce = Client.Execute(Of T)(request)
        If responce.StatusCode <> HttpStatusCode.OK Then
            Throw New InvalidOperationException("Update Failed" & Convert.ToString(responce.StatusCode))
        End If
        Return responce.Data
    End Function

您需要指定共享函数所在的类，或者它将尝试在您所在的对象中使用Update函数。

Public Function Update() As Branch
    Return Resources.Update(Me, Path)
End Function

班级＆＃39;无法编入索引，因为它没有默认属性
