filestream

I am a little confused as to the steps of reading a file into buffer gradually. from the MSDN docs public abstract int Read( byte[] buffer, int offset, int count ) source from C# Examples FileStream fileStream = new FileStream(filePath, FileMode.Open, FileAccess.Read); try { int length = (int)fileStream.Length; // get file length buffer = new byte[length]; // create buffer int count; // actual number of bytes read int sum = 0; // total number of bytes read // read until Read method returns 0 (end of the stream has been reached) while ((count = fileStream.Read(buffer, sum, length - sum)) > 0)

I am wondering if it's possible to get a readonly FileStream to a locked file? I now get an exception when I try to read the locked file. using (FileStream stream = new FileStream("path", FileMode.Open)) Thanks! You should try another constructor. They are documented at MSDN. This one looks like a bet: FileStream Constructor (String, FileMode, FileAccess, FileShare) MSDN Link FileAccess A constant that determines how the file can be accessed by the FileStream object. This gets the CanRead and CanWrite properties of the FileStream object. CanSeek is true if path specifies a disk file. FileShare

How do I read a raw byte array from any file, and write that byte array back into a new file? Marc Gravell (edit: note that the question changed; it didn't mention byte[] initially; see revision 1 ) Well, File.Copy leaps to mind; but otherwise this sounds like a Stream scenario: using (Stream source = File.OpenRead(inPath)) using (Stream dest = File.Create(outPath)) { byte[] buffer = new byte[2048]; // pick size int bytesRead; while((bytesRead = source.Read(buffer, 0, buffer.Length)) > 0) { dest.Write(buffer, 0, bytesRead); } } byte[] data = File.ReadAllBytes(path1); File.WriteAllBytes(path2,

I want to download some content in csv format. It is stored online in a csv file. I can not just read the content. I first have to download the file, open and then read it. Is there a way to open it directly? Or do I have to first load/upload it on my server and then open it like a classic file? Yes, it can open directly using fopen and fgetcsv However, this feature sometime is restricted for security concern, and you can read the details via the documentation http://php.net/manual/en/function.fopen.php http://php.net/manual/en/function.fgetcsv.php Another drawback of open directly, if the

I have the following structures in Delphi 2009: type IndiReportIndi = record IndiName: string; NameNum: integer; ReportIndiName: string; end; var XRefList: array of IndiReportIndi; where XRefList is a dynamic array. I want to save XRefList to a FileStream. How do I do that AND include all the IndiName and ReportIndiName strings so that they will all be retrievable again when I later load from that FileStream? Use: http://code.google.com/p/kblib/ type IndiReportIndi = record IndiName: string; NameNum: integer; ReportIndiName: string; end; TXRefList = array of IndiReportIndi; var XRefList:

I want to convert the stream result output to string since I want to use it in Junit I think that I need to use the string writer but Im not sure how exactly to use it. StreamResult result = new StreamResult(new File("C:\\file.xml")); transformer.transform(source, result); Thanks Fedor Timo Hahn Have a look at and learn to use the javadocs of the StreamResult class ( http://java.sun.com/javase/6/docs/api/ ). One of the constructors of StreamResult takes a Writer object as a parameter. You will see that one of the sub-classes of Writer is StringWriter. So to obtain a string from what is written
