filestream

Is there a way to create directories in a FileTable without using File I/O APIs? Is it just as simple as creating a SQL INSERT statement? This is my first experience with SQL Server 2012 and I'm not familiar with the limits of the FileTable from within SQL Server. The following worked for me. Hopefully this helps out someone else. INSERT INTO FileTable0 (name,is_directory,is_archive) VALUES ('Directory', 1, 0); You should also check out Bob Beauchemin's Techdays 2012 video for more details on FileStream and its evolution into FileTable . 来源： https://stackoverflow.com/questions/10483906/use-sql

I have a function in a C# MVC application that creates a temporary directory and a temporary file, then opens the file using FileStream, returns the FileStream to a calling function, and then needs to delete the temporary files. However, I do not know how to delete the temp directory and file because it always errors out saying "the process cannot access the file because it is being used by another process." This is what I tried, but the FileStream is still using the temp file in the finally block. How can I return the FileStream and delete the temporary files? public FileStream

I want to select a simple .txt file that contains lines of strings using a FileUpload control. But instead of actually saving the file I want to loop through each line of text and display each line in a ListBox control. Example of a text file: test.txt 123jhg345 182bdh774 473ypo433 129iiu454 What is the best way to accomplish this? What I have so far: private void populateListBox() { FileUpload fu = FileUpload1; if (fu.HasFile) { //Loop trough txt file and add lines to ListBox1 } } 62071072SP private void populateListBox() { FileUpload fu = FileUpload1; if (fu.HasFile) { StreamReader reader =

I have the following code: using (MemoryStream str = new MemoryStream()) { Program.api.GetDocument(result, str); using (FileStream fileStream = File.Create(filePath)) { str.WriteTo(fileStream); } } Whenever a file is written, it is always locked afterwards - attempting to delete it or modify it causes Windows to tell me the file is in use, even after closing my application. Am I missing something? Your problem is most likely caused by Windows Search Indexing which is a part of Windows Search . If you attempt to access the file immediately (or very shortly) after modifying it, you may run into

I have a WCF service which allows me to upload files in chunks. What I am wondering is could this code can cause the uploaded stream to be only partially appended to the target stream in any case? I have my logs that shows me that all the sent streams are 512000 byte(which I set on client side) and I've sent 6 chunks out of 9 chunks so far. But on server the files size is 2634325. Which means the last chunk sent(6th) is saved incompletely. What can be causing this behaviour? What should I do to avoid this? Or is this completely safe, and I should look for the bug in somewhere else? public void

How do I read a raw byte array from any file... Dim bytes() as Byte ..and then write that byte array back into a new file? I need it as a byte array to do some processing in between. I'm currently using: To read Dim fInfo As New FileInfo(dataPath) Dim numBytes As Long = fInfo.Length Dim fsAs New FileStream(dataPath, FileMode.Open, FileAccess.Read) Dim br As New BinaryReader(fs) Dim bytes As Byte() = br.ReadBytes(CInt(numBytes)) br.Close() fs.Close() To write Dim fs As System.IO.FileStream fs = New System.IO.FileStream(outpath, System.IO.FileMode.Create) fs.Write(bytes, 0, bytes.Length) fs
