bytearray

问题 I have my below layout in which I need to represent my data and then finally I need to make one byte array out of that. I need to represent my data in the below format from Java code and then send the byte array to my C++ program which in turns c++ program unpacks the byte array and extract the relevant stuff from it - // below is my data layout - // // key type - 1 byte // key len - 1 byte // key (variable size = key_len) // timestamp (sizeof uint64_t) // data size (sizeof uint16_t), this is

问题 I want to play a media file from a memory stream using LibVLC like so: //Ideally it would go like this: LibVLC.MediaFromStream = new MemoryStream(File.ReadAllBytes(File_Path)); Of course this is a very oversimplified version of what I want but hopefully it conveys what I am looking for. The reason being that I want there to be a good amount of portability for what I'm doing without having to track file locations and such. I'd rather have a massive clump of data in a single file that can be

问题 I am trying to send data between 2 process in the form of byte streams, which is working fine for almost all the classes but one problem i am having is that the deserilization fails if the class of the object has a byte array inside it and gives me an error stating the assembly where the serilization took place cannot be loaded. I cannot include the assembly in here because both sender and receiver are different applications. Is there a way to fix this? Edit: Sorry it turns out that even

问题 I am stuck at strange issue. I have a jbpm5.3 web panel and what i am trying to do it to create web services in servlets by manipulating mysql database. i have done all the things but stuck in one byte array. this web panel uses a table workiteminfo in which it saves all the details and uses this byte array for further processing. My problem is that i do not have information about this byte array, but what i got to know is that this byte array is an object an unknown class. If i have this

问题 This question already has answers here : Closed 7 years ago . Possible Duplicate: Is the received stream from a socket limited to a single send command? Note: I see this question very complicated (hopefully not for you guys, that's why Im asking here lol) and I tried my best to explain it as simple and clear as possible. In my application, I'm continually receiving byte arrays in a fix sized buffer. These series of byte arrays that I'm receiving has been serialized 'binarily'. However,

问题 There are many answers to this question here on Stack but none of them are working for me... I need to set the "src" attribute of an image tag in javascript from a byte array that I am retrieving via an ajax call to my controller. I have to do this client side because I am dynamically building some of the html (not shown in my simple example below) Here is the view: <div> <button onclick=" loadFromDb(); ">CLICK ME</button> <img id="imgFromModel" src="data:image/png;base64,@Convert

问题 I am working on a program which converts the inkcanvas strokes to a byte array for encryption and then saves it in a txt file. Essentially I need to convert a byte array to inkcanvas strokes. I have the first half of the code done (which converts the inkcanvas strokes to a byte array): private byte[] InkCanvasToByte() { using (MemoryStream ms = new MemoryStream()) { if(myInkCanvas.Strokes.Count > 0) { myInkCanvas.Strokes.Save(ms, true); byte[] unencryptedSignature = ms.ToArray(); return

问题 I am fetching email from Exchange server using Java EWS API (EWS - Exchange Web Services) and storing it in a proprietary CMS. The type in which I am getting message is microsoft.exchange.webservices.data.EmailMessage - a class provided by EWS API. The CMS API requires ByteArrayOutputStream object as a parameter to its method. So I want to convert EmailMessage object to ByteArrayOutputStream . I saw this thread and tried similar like this: (Below item is of type EmailMessage )

问题 I am going to send a byte array through socket.But I used to work in c/c++ and be new to lua. Now i have a problem,here is my question. i want to send a bytearray.It should contain mac_address,string_length,string. For detail: mac_address:6 bytes length of string: 1 byte string:several bytes (1)first question Now,I have a string of mac_address like“01：2f:c2:5e:b6:a3”,how can I convert it into a 6 byte hex array? (2)second how to define an unsigned number and store it to byte?for example,sting

问题 I need to write bytes of an IEnumerable<byte> to a file. I can convert it to an array and use Write(byte[]) method: using (var stream = File.Create(path)) stream.Write(bytes.ToArray()); But since IEnumerable doesn't provide the collection's item count, using ToArray is not recommended unless it's absolutely necessary. So I can just iterate the IEnumerable and use WriteByte(byte) in each iteration: using (var stream = File.Create(path)) foreach (var b in bytes) stream.WriteByte(b); I wonder
