While browsing forums today I came across a question which asked for a solution to download a file from a web server programmatically. The solution is very simple and below is the code which achieves the goal. Here I am downloading a file asynchronously on Button Click.
1: private void buttonDownloadFile_Click(object sender, EventArgs e) 2: [...]
To make an object cloneable in .NET we should implement ICloneable interface. ICloneable is a simple interface with only one method Clone(). In this post I will show you how to make a deep clone of an object.
class Program { static void Main(string[] args) { Customer c1 = new Customer { FirstName = “John”, [...]
To get a list of installed applications we need to look into registry. Microsoft.Win32 namespace contains objects which can be used to work with Windows Registry.
