frankgeerlings / CamelCaseDisplayNamesModelMetadataProvider.cs

Created October 10, 2013 10:54

Create useful names for fields instead of the camel cased property names. This one is slightly different in that it also capitalizes just the first word, which for some languages is more appropriate than having all the words' first letters as caps. Inspired largely by http://blog.dotsmart.net/2011/03/28/generating-better-default-displaynames-fro…

	using System;
	using System.Collections.Generic;
	using System.ComponentModel;
	using System.Text.RegularExpressions;
	using System.Web.Mvc;

	/// <summary>
	/// Model metadata property names are typically CamelCased. When used as a human-readable text, eg. in LabelFor etc, this metadata provider
	/// will un-camelcase the name of the property, so you don't have to add a DisplayNameAttribute to every single property in your model.
	/// </summary>
