bytearray

问题 [StructLayout(LayoutKind.Explicit)] public struct struct1 { [FieldOffset(0)] public byte a; // 1 byte [FieldOffset(1)] public int b; // 4 bytes [FieldOffset(5)] public short c; // 2 bytes [FieldOffset(7)] public byte buffer; [FieldOffset(18)] public byte[] shaHashResult; // 20 bytes } void DoStuff() { struct1 myTest = new struct1(); myTest.shaHashResult = sha256.ComputeHash(pkBytes); // 20 bytes byte[] newParameter = myTest.ToArray() //<-- How do I convert a struct // to array without a copy?

问题 I need to upload some DATA inside and FTP server. Following stackoverflow posts on how to upload a FILE inside and FTP everything works. Now i am trying to improve my upload. Instead collecting the DATA, writing them to a FILE and then upload the file inside the FTP i want to collect the DATA and upload them without creating a local file. To achieve this i do the following: string uri = "ftp://" + ftpServerIp + "/" + fileToUpload.Name; System.Net.FtpWebRequest reqFTP; // Create FtpWebRequest

问题 I have implemented a very simple class called Enigma which has a symmetric key and two methods: byte[] encryptString(String strToEncrypt) and String decryptBytes(byte[] arrayToDecrypt) . I am trying to write some tests for the methods. I have thought of testing that the encrypt and decrypt methods are the inverse of each other, but that says nothing about each of them individually. I wanted to use the methods as they are now to obtain a battery of input-outputs and set that as the tests (I

问题 I Want to save a PDF file from a byte array and want to save that file on my server map path location. Below is my code snippet. It's giving no errors nor saving the file. You are welcome to correct my syntax if it is wrong or help me by referring other code snippets. byte[] data = (byte[])listDataset.Tables[0].Rows[0][0]; System.IO.FileStream file = System.IO.File.Create(Server.MapPath(".\\TmpImages\\"+hfFileName+".pdf ")); file.Write(data, 0, data.Length); file.Close(); 回答1: It could be a

问题 I'm currently recording sound and storing the byte array for playback and subsequent encoding to mp3. Unfortunately though I am getting a click sound at the very beginning of the recording. I have attempted a couple of methods to try to eliminate this such as: recording the first .3 seconds with mic.gain = 0; then setting mic.gain = 50; clearing the byteArray after the first .3 seconds then continuing to write the bytearray (in effect deleting the first .3 seconds of the recording.) Neither

问题 I am trying to find out how I can pack an integer or float value in to a byte array in Julia. In Python I would just do the following: struct.pack("<q",1) Which would give me '\x01\x00\x00\x00\x00\x00\x00\x00' or for a float: struct.pack("<f",0.1) Is there any package in Julia that provides this? Thanks! 回答1: See the StrPack package: https://strpackjl.readthedocs.org/en/latest/ This is actually one of the oldest Julia packages around. 回答2: A couple other options to StrPack.jl: julia> function
