filestream

问题 I wonder to know how can I make my .html project run not from file:// but as a localhost because one of the functions I've implemented requires getUserMedia which browsers instantly block, when loading from file://. I've done a lot of research on this but I'm still not understanding how it should be done, so if you can, please explain it in detail if it's not too pretentious of me, of course. 回答1: If you are on Ubuntu (or any other similar Linux distro) run apt-get install apache2 then move

问题 I'm passing some Base64 encoded strings through WCF, and I'm attempting to write them to a file. However, despite the fact that my FileStream object has a Length greater than 0, my file on disk remains empty. FileStream fs = new FileStream(Config.Instance.SharedSettings.SaveDir + StudyInstance.StudyId + "\\tmp.ext", FileMode.Create); EncodeBlock eb = new EncodeBlock(); while (eb.Part != eb.OfParts || eb.OfParts == 0) { eb.ToDecode = ps.StudyService.GetInstancePart(StudyInstance, s, eb.Part+ 1

问题 I'm working now on a class that will allow editing very big text files (4Gb+). Well it may sound a little stupid but I do not understand how I can modify text in a stream. Here is my code: public long Replace(String text1, String text2) { long replaceCount = 0; currentFileStream = File.Open(CurrentFileName, FileMode.Open, FileAccess.ReadWrite, FileShare.None); using (BufferedStream bs = new BufferedStream(currentFileStream)) using (StreamReader sr = new StreamReader(bs)) { string line; while

问题 I have been working on Xamarin.Android recently. I need to use pdf generator to send a report via email. I have been came across to the following blog. I do not really know what to put in the FileStream fs = new FileStream (???????); In addition to that, I would like to open or see that pdf on the screen. using System; using Android.App; using Android.Content; using Android.Runtime; using Android.Views; using Android.Widget; using Android.OS; using System.IO; using XamiTextSharpLGPL; using

问题 In my program, I write a file, then call an external program that reads that file. Do I need Flush(true) to make sure that the data is written entirely to disk, or is Flush() sufficient? class ExampleClass : IDisposable { private FileStream stream = File.Open("command-list.txt", FileMode.Append, FileAccess.Write, FileShare.Read); public void Execute(string command) { var buffer = Encoding.UTF8.GetBytes(command); stream.WriteByte(10); stream.Write(buffer, 0, buffer.Length); stream.Flush(true);

问题 I am trying to extract an application resource from My.Resources.FILE I have discovered how to do this with DLL & EXE files, but I still need help with the code for extracting PNG & ICO files. Other file types also. (If possible) Here is my current code that works with DLL & EXE files. Dim File01 As System.IO.FileStream = New System.IO.FileStream("C:\Users\" + Environment.UserName + "\Desktop\" + "SAMPLE.EXE", IO.FileMode.Create) File01.Write(My.Resources.SAMPLE, 0, My.Resources.SAMPLE.Length

问题 I am reading in a file, encrypting the contents, and writing the cipher text back out to a file using PowerShell. When the FileStream object ($inFS) is closed, it creates a file in the pwd (C:\docs) named "0". I opened the file and it had "32" written to it. The encrypted contents are being written to a file in a different directory with no problems. I thought maybe there was something in the buffer still so I tried Flush() and Dispose() but same results. Why is this? $inFile = 'C:\docs

问题 I'm making a call to an MVC controller method. The return type is FileStreamResult. In this method I'm creating an image in the form of a byte array. I'm creating a MemoryStream, passing the byte array in the constructor. I'm then returning a new FileStreamResult object with the memory stream object and "image/png" in the constructor, as my image is a PNG. public FileStreamResult GetImage() { ImageModel im = new ImageModel(); var image = im.GetImageInByteArray(); var stream = new MemoryStream
