filestream

I can open a FileStream with new FileStream(logfileName, FileMode.Open, FileAccess.Read, FileShare.ReadWrite); Without locking the file. I can do the same with File.ReadLines(string path) ? xanatos No... If you look with Reflector you'll see that in the end File.ReadLines opens a FileStream(path, FileMode.Open, FileAccess.Read, FileShare.Read, 0x1000, FileOptions.SequentialScan); So Read-only share. (it technically opens a StreamReader with the FileStream as described above) I'll add that it seems to be child's play to make a static method to do it: public static IEnumerable<string> ReadLines

I've searched all over but can't find an answer to this question. I understand that FileAccess deals with file access on the machine and FileShare deals with the share, but I can't find an explanation of how exactly it comes together and how they impact one another. For example, if I have using ( FileStream fs = new FileStream( pathName, FileMode.Open, FileAccess.Read, FileShare.ReadWrite) ) does that mean that users on the machine can only read the file whilst users remotely accessing the folder can read and write to the file? Additionally, what would the impact be in using using ( FileStream

So, I'm trying to find a way to fgets() a specific line in a text file in C, to copy the contents of the line into a more permanent buffer: Essentially, I was wondering if there was a way to do that without something similar to the following code: FILE *fp; fp = fopen(filename, "r"); char line[256]; char * buffer; int targetline = 10; while( targetline > 0) { fgets(line, 256, fp) } buffer =(char*)malloc(sizeof(char) * strlen(line)); strcpy(buffer, line); So basically I don't want to iterate through the file n-1 times just to get to the nth line... it just doesn't seem very efficient (and, this

I need a way to read a Excel file from a stream. It doesn't seem to work with the ADO.NET way of doing things. The scenario is that a user uploads a file through a FileUpload and i need to read some values from the file and import to a database. For several reasons I can't save the file to disk, and there is no reason to do so either. So, anyone know of a way to read a Excel file from a FileUpload stream? It seems i found a soultion to the problem myself. http://www.codeplex.com/ExcelDataReader This library seems to work nicely and it takes a stream to read the excel file. ExcelDataReader

I don't understand what I'm doing wrong here. I generate couple of memory streams and in debug-mode I see that they are populated. But when I try to copy MemoryStream to FileStream in order to save the file fileStream is not populated and file is 0bytes long (empty). Here is my code if (file.ContentLength > 0) { var bytes = ImageUploader.FilestreamToBytes(file); // bytes is populated using (var inStream = new MemoryStream(bytes)) // inStream is populated { using (var outStream = new MemoryStream()) { using (var imageFactory = new ImageFactory()) { imageFactory.Load(inStream) .Resize(new Size

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.arachsys.com/csharp/readbinary.html public static byte[] ReadFully(Stream stream, int initialLength) { // If
