看来，为什么我得到一个错误的请求（400错误）问题 - 请参考上面的主题 - 是因为这个错误的。结帐下面的屏幕截图：
It seems that the problem why I'm getting a Bad Request (400 error) - refer to the topic above - is because of this error. Checkout the screen shot below:
因此，大家可以看到，有被抛出一个异常，这可能是什么导致所有的烂摊子。我试图用一个的MemoryStream ，但我得到一个异常告诉我说不能投了 System.Net.ConnectStream 来一的MemoryStream 。那么，如何解决这个问题？
So as you can see, there's an exception being thrown and that's probably what's causing all the mess. I tried using a MemoryStream but I got an exception telling me that it cannot cast a System.Net.ConnectStream to a MemoryStream. So how can I solve this problem?
推荐答案
这是一个虚假的领先。忽略。你只看到，由于调试器/ Visualiser的试图向你展示所有属性（其中一些没有意义未知长度的流）。
That is a false lead. Ignore that. You are only seeing that because of the debugger / visualiser trying to show you all the properties (some of which don't make sense for a stream of unknown length).
这是说，我不知道它是如何有意义的补充，流视图的数据。流是的管道的，不是的水桶的。除了少数例外，他们实际上并不持有该数据 - 他们只是中介机构的数据源/汇
That said, I'm not sure how it makes sense to add that stream to view-data. Streams are pipes, not buckets. With a few exceptions they don't actually hold the data - they are just intermediaries to a data source / sink.
在找到一个实际的问题方面，需要抓是在code发生实际的异常。忽略任何你在Visualiser的看;这不是你的code使用的东西。
In terms of finding an actual problem, you need to catch the actual exception that is happening in the code. Ignore anything you see in the visualiser; that is not what your code uses.
我的犯罪嫌疑人的这一连接流（我不熟悉）拟用作汇 - 意思是：你写吧。然而，序列化（用于查看数据）它可能会尝试的阅读的它。这只是假设，但是，除非您指示实际的异常，你的code是提高（忽略Visualiser的）。
I suspect this "connect" stream (I'm not familiar) is intended to be used as a sink - meaning: you write to it. However, to serialize (for view-data) it might be trying to read it. This is just supposition, however, unless you indicate the actual exception that your code is raising (ignoring the visualiser).
