Hi friends, in this article I will explained about how to
write to a Text file or a notepad file or a .txt file or AppendText() method in .NET.
I already explained in the previous article How to Create a Text File or notepad file using C# and VB.NET, in
that i was using CreateText()
method. If you want to write the data to a already file then we are using the AppendText() method.
