将 RepeatedField<ByteString> 转换为 Byte[]

Question

在 Docker 中定义了一个 gRPC Python 服务。

我的 PROTO 文件中的服务：

rpc ClientCommand(ClientRequest) returns (ClientResponse){}

“ClientResponse”的定义：

message ClientResponse{
          int32  request_id             = 1;
 repeated int32  prediction_status      = 2;
 repeated string prediction_info        = 3;
 repeated string prediction_error       = 4;
 repeated string prediction_result_name = 5;
 repeated bytes  prediction_result      = 6;
 repeated bytes  prediction_config      = 7;
 repeated bytes  prediction_log         = 8;
 }

在客户端，我想捕获重复的字节并将它们转换成一个文件（我知道它更适合流，但目前我想这样做）。重复的字符串和整数我可以完美转换成List --> OK
我想将重复的字节转换为 Byte[]。他们的类型：Google.ProtoBuf.Collections.RepeatedField.

起初似乎无法将此类型转换为 Byte[]。有人可以帮我解决这个问题吗？我的临时解决方案：

byte[] test = new byte[100];
Google.Protobuf.ByteString[] test2 = new Google.Protobuf.ByteString[100];
response.PredictionResult.CopyTo(test2,0);
test2.CopyTo(test,0);
WriteFile(@"C:\programs\file.txt", test);

与此同时我想通了：

public void WriteFileResult(string fileName,Google.Protobuf.Collections.RepeatedField<ByteString> data)
{
    byte[] bytes = new byte[data.Count];
    ByteString[] dataByteString = new ByteString[data.Count];
    
    string path = Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location);
                if (!path.EndsWith(@"\")) path += @"\";
    
                if (File.Exists(Path.Combine(path, fileName)))
                    File.Delete(Path.Combine(path, fileName));
        
         using (FileStream fs = new FileStream(Path.Combine(path, fileName), FileMode.CreateNew, FileAccess.Write))
                    {
                        
                        data.CopyTo(dataByteString, 0);
                        bytes = dataByteString[0].ToByteArray();
                        
                        fs.Write(bytes, 0, (int)bytes.Length);
                        _serviceResponseModel.Json = false;
                        //fs.Close()
                    }
}
