This startup article explains the concept of file manipulations, such as reading from a file, writing to a file and deleting a file, in ASP.NET from the ground up.

When uploading a file to a web server, the upload process generally requires the incoming file to be stored in memory until the upload is complete. If an uploaded file is larger than the available memory, memory usage in general and performance in particular will suffer.
Typically, the uploaded file is either held in memory or the length of the posted file is checked and refused the file if it is too large. The streaming solution presented in this article allows you to grab an uploaded fi...

I often deploy ASP.NET websites to servers that I don't control. In these situations, I can't get to the underlying file system to do any file maintenance, because I don't have direct access to the server. So I have to access the file system indirectly, through the website that I am deploying. Rather than writing a bunch of special purpose pages to deal with file management, I developed a generic WebFileManager page than can be dropped into any ASP.NET website. This page performs the most common...

In our real life applications it is required to read, write, or manipulate files and directories. The .NET Framework provides a set of classes in the System.IO namespace to allow synchronous and asynchronous reading from and writing to data streams and files. Before working with files and directories it is essential to make sure that security permissions are set properly on folders and files where you want to write. The .NET Framework runs all ASP.NET processes under the local ASPNET account....

Isolated storage is a file storage mechanism without knowing the actual physical location. The objects to utilize this reside in the System.IO.IsolatedStorage namespace, although some of the enumerations needed for isolated storage operations are in the System.IO namespace. This storage area is beneath the user's Application Data folder (see Figure 1), which the folders/files are unique to a user and .NET assembly. However, the security for these files can be an issue. Administrators on the syst...

MemoryMappedCache is a small project can be used to host a proactive loaded cache using a Windows Service. This cache uses Memory Mapped Files internally. Other applications on the same computer can then also use MemoryMappedCache to access information stored in this cache. This is done much quicker than using .NET Remoting. A significant amount of time was spent to ensure that this cache can be accessed from within ASP.NET if the cache is hosted by a Windows Service....

In a web application, the most common requirement for storing configuration is like this:
* You have a static singleton class (e.g. MyConfiguration) which stored the configuration data. It has properties like "DatabaseConnectionString" to store configuration settings
* You need to store it in a XML file.
* You do not want to store it in web.config because whenever you change the values, your web application restarts
* You want to programmatically modify the config...

The rules of hangman are quite simple. There's a secret word that you must guess by choosing one letter at a time. If you chose a letter that appears one or more times in the secret word, the letters and their positions are revealed. If, however, you guess a letter that is not in the secret word, then a piece of the man being hanged is added to the gallows. If you incorrectly guess six letters, the complete hangman character is drawn, meaning you lose!...

I am developing an ASP application in which the user enters some information in screen A. After processing this information, I display screen B. But the processing sometimes takes a while, so I want to display a screen between A and B that says "Please wait..." or " Processing....". In the interim, I�ll do the processing while that screen is displayed, then automatically switch to screen B when ready. I want to avoid any client-side scripting, so I need to process the information on the server...

In this time you need a file manager and creating a powerful solution is time consuming, but you don't have enough time. This was the story of my work when I needed it.

The ZipEntryHandler enumerates and serves files out of static zip files deployed in your web space. The handler is implemented as a simple ASP.NET IHttpHandler deployed with a code file in the App_Code directory on your website and configured with a line in the web.config file. The handler is very useful for several purposes:
* Serving otherwise prohibited files - Code files with extensions that have special meaning to the web application ("cs", "vb", "aspx") can be served statically.
