c # Format a String as Currency

When building a string for output to a web page, it’s useful to format any currency value in a human-friendly money format. This is extremely easy in C#.

The system format string works like this: {0:C}

For example, the following code example:

decimal moneyvalue = 1921.39m;

string html = String.Format("Order Total: {0:C}", moneyvalue);

Console.WriteLine(html);

Outputs the following:

Order Total: $1,921.39

It’s worth noting that you must pass in a numeric value to the String.Format statement. If you pass in a string value, it won’t format correctly. If your currency value is in a string, you need to convert it into a double first.

Get IP Address from DNS Hostname in C#

 

A frequent task when designing applications that work with TCP/IP and the internet is to lookup an IP address from a hostname. It’s much easier for users to deal with the hostname than having to type in an IP address.

First you’ll add the System.Net namespace to your using section:

using System.Net;

Example of code to get address from hostname:

string code2all = "www.google.com";

IPAddress[] addresslist = Dns.GetHostAddresses(code2all);

foreach (IPAddress theaddress in addresslist)

{

Console.WriteLine(theaddress.ToString());

Console.Read();

}

you can change site google.com to any site you want
