bytearray

问题 I have a byte array in pdf format getting from web service.Now I want to view in PDF file but no luck. sample byte[]: JVBERi0xLjQKJeLjz9MKMSAwIG9iaiAKPDwKL01hdHJpeCBbMSAwIDAgMSAwIDBdCi9TdWJ0eXBlIC9Gb3JtCi9GaWx0ZXIgL0ZsYXRlRGVjb2RlCi9MZW5ndGggMTUwMzc3Ci9SZXNvdXJjZXMgCjw8Ci9FeHRHU3RhdGUgCjw8Ci9HUzAgMiAwIFIKL0dTMSAzIDAgUgo+PgovQ29sb3JTcGFjZSAKPDwKL0NTMCA0IDAgUgo+PgovUHJvcGVydGllcyAKPDwKL01DMyAKPDwKL01ldGFkYXRhIDUgMCBSCj4+Ci9NQzIgCjw8Ci9NZXRhZGF0YSA2IDAgUgo

问题 In Java, I can't take a byte array of unsigned bytes (from something such as Wire Shark) and put this into java.... Because I will get compile errors since anything greater than 127 decimal/0x07F is treated not as a byte, but as an int.... IE: byte[] protocol = { 0x04, 0x01, 0x00, 0x50, /*error*/0xc1, /*error*/0xdb, 0x1c, /*error*/0x8c, 0x4d, 0x4f, 0x5a, 0x00 }; Need a good way to handle taking unsigned char arrays and putting them into Java as literals. 回答1: Cast them to (byte). 来源： https:/

问题 I have an Air application with remote service in codeigniter. I'm trying to save a bytearray that I received from the Air app but when I save the data I get empty files with the correct filename. So there must be something wrong with my bytearray or the way I save the data. Does anyone have an idea what I'm doing wrong? I've debugged the Arraycollection I sent and the bytearray is definitely in there. public function uploadImage($image) { foreach($image as $img) { $file = $img['name']; $data

问题 I have to make a RSA signature (on a state machine) in C on a 32bit board. I am limited on memory so I can not store decimals in a vector or something like that. The best thing would be if I could store bits and to have easy access to them; what storage method would be best? I made this one: #if (CPU_TYPE == CPU_TYPE_32) typedef uint32_t word; #define word_length 32 typedef struct BigNumber { word words[64]; } BigNumber; #elif (CPU_TYPE == CPU_TYPE_16) typedef uint16_t word; #define word

问题 I am getting an error reading: Cannot implicitly convert type 'String' to 'Byte[]' I think 'byte[]' is byte array - if it isn't please correct me. I have tried another solution on this website but I did not understand. I'm making a c# 'RTM tool' and this is what put in : byte[] bytes = (metroTextBox2.Text); Array.Resize<byte>(ref bytes, bytes.Length + 1); PS3.SetMemory(0x2708238, bytes); 回答1: You can try like this: string str= "some string"; var bytes = System.Text.Encoding.UTF8.GetBytes(str)

问题 I am creating several byte arrays that need to be joined together to create one large byte array - i'd prefer not to use byte[]'s at all but have no choice here... I am adding each one to a List as I create them, so I only have to do the concatenation once I have all the byte[]'s, but my question is, what is the best way of actually doing this? When I have a list with an unknown number of byte[]'s and I want to concat them all together. Thanks. 回答1: listOfByteArrs.SelectMany(byteArr=>byteArr)

问题 I am tying to upload large files(1 GB+) to Google Drive using GoogleDrive API. My code works fine with smaller files. But when it comes to larger files error occurs. Error occurs in the code part where the the file is converted into byte[]. byte[] data = System.IO.File.ReadAllBytes(filepath); Out of memory exception is thrown here. 回答1: Probably you followed developers.google suggestions and you are doing this byte[] byteArray = System.IO.File.ReadAllBytes(filename); MemoryStream stream = new

问题 I need to convert a system-generated GUID into a Byte[16] array and then convert those decimal values into a hex value string. Crazy, I know and I'm very open to a more efficient approach than the ones I've tried! I've tried PHPs unpack() function on this GUID but can't seem to get the right format. I've tried c*, C* and all of the other possible formats. Here's the GUID I'm starting with: GUID: dwRhRSIjlGXhAAAAkuFQ0A The Byte[16] array I'm trying to populate should look like this: $bytearray
