我正在尝试使用可在此处找到的Microsoft.Hadoop.Avro库反序列化二进制avro文件。
https://azure.microsoft.com/en-us/documentation/articles/hdinsight-dotnet-avro-serialization/
我没有在C＃应用程序中使用库，而是使用Powershell来尝试反序列化。最初我导入Hadoop库以及依赖的Newtonsoft.json库。我通过使用Add-Type cmdlet执行此操作。完全没问题。尝试在源avro文件流上调用AvroSerializer类的Deserialize方法后，问题就出现了。以下是调用链的脚本，并在尝试反序列化avro文件流时返回异常。

我无法弄清楚我在这里做错了什么。
