TProtocol protocol = new TBinaryProtocol(new MemoryStream()); DictionaryIn this example, we create a dictionary and write it to a binary Thrift message using the TBinaryProtocol. We then use the WriteMapEnd method to close the map definition. Next, we seek back to the beginning of the message and use the ReadMapBegin method to read the map definition. Finally, we use the ReadString method to read the key-value pairs in the map until we reach the end of the map definition with the ReadMapEnd method. Package library: The Thrift.Protocol TProtocol ReadMapEnd method is part of the Apache Thrift framework, which is an open-source software project maintained by the Apache Software Foundation. It is included in the Apache Thrift .NET library, which provides a C# implementation of the Apache Thrift messaging protocol.data = new Dictionary (); protocol.WriteMapBegin(TType.String, TType.String, data.Count); foreach (KeyValuePair pair in data) { protocol.WriteString(pair.Key); protocol.WriteString(pair.Value); } protocol.WriteMapEnd(); // close map definition protocol.Transport.Seek(0, SeekOrigin.Begin); protocol.ReadMapBegin(); // read map definition while (protocol.ReadMapEnd()) { string key = protocol.ReadString(); string value = protocol.ReadString(); Console.WriteLine("{0}: {1}", key, value); }
