将C＃中的内存流导入Qt的功能

Question

您能告诉我如何通过Qt lib将C＃中的这些函数重写为C ++吗？

private MemoryStream _memoryStream= new MemoryStream();

_memoryStream.ReadByte();
_memoryStream.Read(Byte[] buffer, Int32 offset, Int32 count);
_memoryStream.Write(Byte[], Int32 offset, Int32 count)
_memoryStream.WriteByte(Byte)
_memoryStream.WriteTo(Stream stream);
