Dado.ComponentModel.Mutations 0.5.1

Sample Usage

The following class shows that a property should be converted to lowercase and replaced of invalid characters.

using System.Text.RegularExpressions;

public class User
{
	private string _userName;

	public string UserName {
		get {
			return _userName;
		}
		set {
			value = value.ToLower();

			_userName = Regex.Replace(value, @"[^a-z0-9._]", String.Empty);
		}
	}
}

Altering the example to use a mutation attributes will produce the following code.

using Dado.ComponentModel.DataMutations;

public class User
{
	[
		ToLower,
		RegexReplace(@"[^a-z0-9._]")
	]
	public string UserName { get; set; }
}

Now, when Mutator.Mutate(context); is executed the value of User.UserName will be lowercased and have all invalid characters replaced.
