You can use one of methods from ByteString class to convert string to ByteArray ByteString.copyFromUtf8(stringText).

According to the docs, Google.ProtocolBuffers.ByteStreamneeds an encoding to know how to display its content. Use ByteStream.ToString(Encoding encoding) or ByteStream.ToStringUtf8().

Your string has been successfully converted to ByteStream. If you see {Google.ProtocolBuffers.ByteString} in the watch window, it simply means that the ByteStream does not override the ToString method. In short, Visual Studio doesn't know how to display a ByteStream, and therefore just display the type name instead.

That said, there is an overload of the CopyFrom method that allows you to directly use a string:

var APP_DEF_TEA_KEY = ByteString.CopyFrom("e#>&*m16", Encoding.Unicode);
