任何帮助，非常感谢。

我正在为 Azure 存储表使用 1.6 SDK。在 UpdateObject() 我收到以下错误：

<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<error xmlns="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata">
  <code>InvalidInput</code>
  <message xml:lang="en-US">One of the request inputs is not valid.

Time:2012-08-08T01:25:32.4366914Z</message>
</error>

这是请求（来自 Fiddler）：

这是对 UpdateObject() 的调用：

Public Sub Update(existingItem As UserDataModel)
    _ServiceContext.AttachTo(UserDataServiceContext.UserTableName, existingItem, "*")
    _ServiceContext.UpdateObject(existingItem)
    _ServiceContext.SaveChanges()
End Sub

下面是初始化服务上下文的代码：

Public Sub New()
    Try
        Dim storageAccount = CloudStorageAccount.FromConfigurationSetting("DataConnectionString")
        _ServiceContext = New UserDataServiceContext(storageAccount.TableEndpoint.ToString(), storageAccount.Credentials)
        _ServiceContext.IgnoreResourceNotFoundException = True
        ' Create the tables
        ' In this case, just a single table.  
        storageAccount.CreateCloudTableClient().CreateTableIfNotExist(UserDataServiceContext.UserTableName)
    Catch ex As Exception
        Debug.WriteLine("Problem with New() UserDataSource. Error: " & ex.Message)
    End Try
End Sub

如果还有什么我可以提供的，请告诉我...

干杯，

The URL looks wrong, but I'm not sure how it got that way... it should normally be something like https://<account>.table.core.windows.net/<table>(PartitionKey='<pkey>',RowKey='<rkey>'). But I have no explanation for why yours doesn't look right. (The code looks fairly straightforward.)

Are you able to perform other operations, like an insert? Do the URLs look right in Fiddler when you do that?
