bytearray

问题 In my code, I am sending a txt file encoded into a byte array over the internet, and then converting the message back on the other side and displaying it. The problem is that when I try displaying it, it always comes out as "[B@1ef9f1d" or "[B@1764be1" etc. This is what recieves the data private void parsePacket(byte[] data, InetAddress address, int port) { String datasent[] = (new String(data).trim()).split(","); String type = datasent[0]; String message = datasent[1]; switch(type){//Data we

问题 Is there any Stream reader Class to read only number of char from string Or byte from byte[] ? forexample reading string: string chunk = streamReader.ReadChars(5); // Read next 5 chars or reading bytes byte[] bytes = streamReader.ReadBytes(5); // Read next 5 bytes Note that the return type of this method or name of the class does not matter. I just want to know if there is some thing similar to this then i can use it. I have byte[] from midi File. I want to Read this midi file in C#. But i

问题 Someone asked me what the difference between the two method parameters and why you would use the ... over specifically assigned array. putMessage(byte ...send) putMessage(byte[] send) I couldn't answer them with confidence and couldn't remember what the ... is called. 回答1: The first one is with Varargs. In short A. First can be used to call with single byte type arg, 2 byte args.. or many args or an array. B. second will be used with array only. 回答2: The ... in your first example are called

Here is the code I use to start the download: WebClient webClient = new WebClient(); webClient.DownloadDataCompleted += new DownloadDataCompletedEventHandler

问题 C#: What takes up more memory? A string or bytes? Let's say I have a line that reads "My Text", in which form would that line use up more memory, as a byte or a string? 回答1: The byte array. This will store your text as ASCII (1 byte per character) characters, whereas a .NET string uses Unicode which are larger. However remember that .NET strings are probably more useful and in a large application the difference probably won't make a huge difference. (note also that if you just use ASCII

问题 I am working on a tool that generates random data for testing purposes. See below the part of my code that is giving me grief. This works perfectly and faster(takes around 20 seconds) than conventional solutions when the file is around 400MB, however, once it reaches around 500MB I am getting an out of memory error. How can I pull contents from the memory and write it in a file progressively having not more than 10 MB in my memory at a single time. def createfile(filename,size_kb): tbl =
