ChangeIISSiteBinding.cs

void ChangeSiteBinding(string siteName, string newBindingValue, string protocol)
{
	using (ServerManager manager = new ServerManager())
	{
		// Find the site by name from IIS
		Microsoft.Web.Administration.Site site = manager.Sites.Where(q => q.Name == siteName).FirstOrDefault();
		if (site == null)
		{
			throw new Exception("The specified site name does not exist in IIS!");
		}
		else
		{
			bool found = false;

			// Loop through all the site's bindings
			foreach (var binding in site.Bindings)
			{
				// If the binding protocol matches the passed protocol, continue
				if (binding.Protocol.Equals(protocol))
				{
					
						// Set this to indicate the binding was found
						found = true;
						// Set the binding value to the new passed value
						binding.BindingInformation = newBindingValue;
						break;
					
				}
			}

			if (found)
			{
				// If the binding was found and changed, commit the changes.
				manager.CommitChanges();
			}
			else
			{
				// If the binding was not found, throw an exception indicating as much.
				throw new Exception("The specified old binding does not exist on this site!");
			}
		}
	}
}
