Introduction
This article is focused on understanding the Directory class of System.IO namespace. The Directory class exposes routines for manipulating directories & subdirectories. It contains all kinds of routines like creating, moving, and enumerating through directories and subdirectories. In most of the application developments we require some file accesses or directory accesses normally we use some [...]

This is a simple program that shows a bit ofhow to manipulate files in Visual C#.Net.I developed this as a "C# Console Application" and this simple programacts like a "DOS" operating system. The only file needed for theapplication is the "MyClass.cs". Open the "ReadMe" file in the zippedfile to see it's usage.

INTRODUCTION:
This article covers the information of how toread or write (Unicode) character based data through TextReader andTextWriter. The TextReader and TextWriter are base classes. TheStreamReader and StringReader derives from the abstract typeTextReader. Similarly the StreamWriter and StringWriter derives fromthe abstract type TextWriter.
STREAMWRITERS & STREAMREADERS:
As I mentioned earlier StreamWriter typederives from a base class named TextWriter. [...]

C-Sharp provides a File class which is used in manipulating text files. The File class is within the System namespace. Also we can use the StreamReader and StreamWriter classes, which are within the System.IO, namespace for reading from and writing to a text file. In this article we'll see examples of Creating a text file, [...]
