bytearray

问题 I know there is no .Net function that exists for checking, but is there an algorithm or easy and effective way of checking if a byte is a valid image before I use the byte array. I need this because I'm sending different commands to a server who is constantly listening to the client and one of the commands is to get the screenshot of the server's computer. 回答1: You can try to generate an image from the byte array and check for the ArgumentException if its not. public static bool IsValidImage

问题 I have a byte array of size 4 byte[] source = new byte[4]; Now I wanted to convert this source into a 4-byte float value... Can anyone tell me how to do this... 回答1: Try float myFloat = System.BitConverter.ToSingle(mybyteArray, startIndex); 来源： https://stackoverflow.com/questions/2619664/c-convert-byte-array-into-a-float

问题 I'm writing a web application in Google app Engine. It allows people to basically edit html code that gets stored as an .html file in the blobstore. I'm using fetchData to return a byte[] of all the characters in the file. I'm trying to print to an html in order for the user to edit the html code. Everything works great! Here's my only problem now: The byte array is having some issues when converting back to a string. Smart quotes and a couple of characters are coming out looking funky. (?'s

问题 I recently came across the issue of needing to frequently (& easily) convert & extract bytes from a BigEndian byte array that was being received over TCP. For those unfamiliar with Big/Little Endian, the short version is that each number was sent as MSB then LSB. When processing and extracting values from the byte array using the default BitConverter on a Little Endian system (read: just about any C#/windows machine), this is a problem. 回答1: Here are some handy extension methods that I

问题 I am trying to generate a PDF from an ODT template file which contain the fields i need to populate. I wanted to get the byte array of this ODT template which is present in the root folder of my project. My application is in such a way that the byte array is provided to generate the PDF. Is there any specific method to generate the byte array without losing the properties of the template..? 回答1: Try this may help you : URL url = this.getClass().getResource("/your_file"); File templateFile =

问题 It would be nice if the .NET framework just gave functions/methods from the BitConverter class that just explicitly returned an array of bytes in the proper requested endianness. I've done some functions like this in other code, but is there a shorter more direct way? (efficiency is key since this concept is used a TON in various crypto and password derivation contexts, including PBKDF2, Skein, HMAC, BLAKE2, AES and others) // convert an unsigned int into an array of bytes BIG ENDIEN // per

问题 I am using a web service, WCF, to return a PDF file in byte array format. I was just returning the pdf file that I had in resources like this: public byte[] displayPDF(string pdfName){ return Service.Properties.Resources.testFile; } However on the client side when I receive the byte array and write it to a file on my computer using this: HttpClient client = new HttpClient(); client.MaxResponseContentBufferSize = 9999999; var uri = new Uri("http://TestSite.azurewebsites.net/Service.svc/webHttp

问题 I have a byte array with audio samples. I want to play it, so I try to write it into SourceDataLine: SourceDataLine sample; private byte[] samplebytes; ... sample.start(); sample.write(samplebytes, 0, samplebytes.length); sample.drain(); sample.stop(); sample.close(); sample = null; And I get this: java.lang.NullPointerException at virtualcut.Sample.<init>(Sample.java:45) at virtualcut.model.SelectionModel.setPosition(SelectionModel.scala:79) at draggable.DraggableComponent$2.mouseReleased

问题 I am having problems of conversion through string->byte->byte[] What I have done so far: double db = 1.00; double ab = db*100; int k = (int) ab; String aa = String.format("%06d", k); String first = aa.substring(0,2);`` String second = aa.substring(2,4); String third = aa.substring(4,6); String ff = "0x"+first; String nn = "0x"+second; String yy = "0x"+third; I want to write those bytes to an byte[]. What I mean is: byte[] bytes = new byte[]{(byte) 0x02, (byte) 0x68, (byte) 0x14, (byte) 0x93,
