stream

问题 PSPS: (a Pre-scripted Post-script) It has just come to mind that a more prescient question would have included the notion of: Is this non-display of "0x"(showbase) for zero-value integers a standard behaviour, or is it just a quirk of my MinGW implementation? It all began on a pleasant Sunday morning... I want to dump some Handles in their hex representation, and in a consistant, formatted way. I want a leading 0x and a fixed width , but this is proving to be elusive using the expected stream

问题 string url = re["response"][0]["url"].ToString(); MediaElement mm = new MediaElement(); mm.Source = new Uri(url,UriKind.RelativeOrAbsolute); mm.AutoPlay = true; mm.Volume = 0.7; mm.Play(); But no changes, the adudio not starts.How I can resolve this? 回答1: You need to add your MediaElement to your VisualTree before playing it, since you're creating it in the codebehind. For example, assuming you have LayoutRoot and that your url is correct, this should work. string url = re["response"][0]["url

问题 I'd like to loop through an object and pass an array of file paths to gulp.src on each iteration and then do some processing on those files. The code below is for illustration purposes and won't actually work since the return statement kills the loop on the first pass. gulp.task('js', function(){ for (var key in buildConfig.bundle) { return gulp.src(bundleConfig.bundle[key].scripts) .pipe(concat(key + '.js')); // DO STUFF } }); That's the basic idea. Any ideas on how to do this? 回答1: I was

问题 According to the answer here I want to write multiple files stream to one stream as following: 4 byte reserved for length number of each stream each stream content write after it's length number(after 4 byte) at the end stream will be something like this Stream = File1 len + File1 stream content + File2 len + File2 stream content + .... Example code: result = new ExportResult_C() { PackedStudy = packed.ToArray() , Stream = new MemoryStream() }; string[] zipFiles = Directory.GetFiles(zipRoot);

问题 Let's suppose that have a stream of text (or Reader in Java) that I'd like to check for a particular string. The stream of text might be very large so as soon as the search string is found I'd like to return true and also try to avoid storing the entire input in memory. Naively, I might try to do something like this (in Java): public boolean streamContainsString(Reader reader, String searchString) throws IOException { char[] buffer = new char[1024]; int numCharsRead; while((numCharsRead =

问题 I'm using Filestream for read big file (> 500 MB) and I get the OutOfMemoryException. I use Asp.net , .net 3.5, win2003, iis 6.0 I want this in my app: Read DATA from Oracle Uncompress file using FileStream and BZip2 Read file uncompressed and send it to asp.net page for download. When I read file from disk, Fails !!! and get OutOfMemory... . My Code is: using (var fs3 = new FileStream(filePath2, FileMode.Open, FileAccess.Read)) { byte[] b2 = ReadFully(fs3, 1024); } // http://www.yoda

问题 I serialize an array of large objects to a json http response stream. Now I want to deserialize these objects from the stream one at a time. Are there any c# libraries that will let me do this? I've looked at json.net but it seems I'd have to deserialize the complete array of objects at once. [{large json object},{large json object}.....] Clarification: I want to read one json object from the stream at a time and deserialize it. 回答1: In order to read the JSON incrementally, you'll need to use
