answer在无法实例化HttpClient的最新版本中不再起作用。

解决方法

您仍然可以在v3中实例化阅读器API。唯一的区别是，您应该使用Create而不是new，并且如果可能的话：请使用新的ProtoReader.State API。除此之外，它应该保持大致相同。另外，您不再需要MemoryStream（您可以直接使用诸如byte[]之类的原始缓冲区）。

以下是使用v3和State API的翻译版本：

static void Main()
{
    byte[] arr = // ...
    var reader = ProtoReader.State.Create(arr,null,null);
    try
    {
        WriteTree(ref reader);
    }
    finally
    {   // the rules on when you can "using" a ref-type
        // are ... complicated
        reader.Dispose();
    }
}
static void WriteTree(ref ProtoReader.State reader)
{
    while (reader.ReadFieldHeader() > 0)
    {
        Console.WriteLine(reader.FieldNumber);
        Console.WriteLine(reader.WireType);
        switch (reader.WireType)
        {
            case WireType.Varint:
                // warning: this appear to be wrong if the 
                // value was written signed ("zigzag") - to
                // read zigzag,add: pr.Hint(WireType.SignedVariant);
                Console.WriteLine(reader.ReadInt64());
                break;
            case WireType.String:
                // note: "string" here just means "some bytes"; could
                // be UTF-8,could be a BLOB,could be a "packed array",// or could be sub-object(s); showing UTF-8 for simplicity
                Console.WriteLine(reader.ReadString());
                break;
            case WireType.Fixed32:
                // could be an integer,but probably floating point
                Console.WriteLine(reader.ReadSingle());
                break;
            case WireType.Fixed64:
                // could be an integer,but probably floating point
                Console.WriteLine(reader.ReadDouble());
                break;
            case WireType.StartGroup:
                // one of 2 sub-object formats
                var tok = reader.StartSubItem();
                WriteTree(ref reader);
                reader.EndSubItem(tok);
                break;
            default:
                reader.SkipField();
                break;
        }
    }
}

（非State API仍然可以使用，但这是首选）
