title: Parse StringValueAttribute to return Enum
body: <p>I currently have a windows phone 8.1 runtime project with enums that use a string value attribute. I want to be able to get an enum value by using the string value attribute, for example use "world" to get the enum value of summer. I am using Windows phone 8.1 runtime so most methods that I have found do not work. </p>
  
  <p>Thanks in advance. </p>
  
  <pre><code>public enum test  
  { 
      [StringValue("hello")] 
      school, 
      [StringValue("world")] 
      summer, 
      [StringValue("fall")] 
      car 
  } 
  
  public class StringValueAttribute : Attribute 
  { 
      private string _value; 
      public StringValueAttribute(string value) 
      { 
         _value = value;
      } 
  
      public string Value 
      { 
         get { return _value; } 
      } 
  } 
  </code></pre>
