Can I pass MVC to automatically split pascal properties into words?

Question

I often have c # code like

    [DisplayName("Number of Questions")]
    public int NumberOfQuestions { get; set; }

Where I use the property DisplayNameto add to spaces when it is displayed. Can MVC be specified to add default spaces if the annotation DisplayNameis not explicitly specified?

thank

There are two ways.

1. Press LabelFor and create your own HTML-assistant:

• Utility class for custom HTML helper:

  public class CustomHTMLHelperUtilities
  {
  // Method to Get the Property Name
  internal static string PropertyName<T, TResult>(Expression<Func<T, TResult>> expression)
   {
      switch (expression.Body.NodeType)
      {
          case ExpressionType.MemberAccess:
              var memberExpression = expression.Body as MemberExpression;
              return memberExpression.Member.Name;
          default:
              return string.Empty;
      }
   }
   // Method to split the camel case
   internal static string SplitCamelCase(string camelCaseString)
   {
      string output = System.Text.RegularExpressions.Regex.Replace(
          camelCaseString,
          "([A-Z])",
          " $1",
          RegexOptions.Compiled).Trim();
      return output;
   }
  }
  

• User Assistant:

  public static class LabelHelpers
  {
   public static MvcHtmlString LabelForCamelCase<T, TResult>(this HtmlHelper<T> helper, Expression<Func<T, TResult>> expression, object htmlAttributes = null)
    {
      string propertyName = CustomHTMLHelperUtilities.PropertyName(expression);
      string labelValue = CustomHTMLHelperUtilities.SplitCamelCase(propertyName);
  
      #region Html attributes creation
      var builder = new TagBuilder("label ");
      builder.Attributes.Add("text", labelValue);
      builder.Attributes.Add("for", propertyName);
      #endregion
  
      #region additional html attributes
      if (htmlAttributes != null)
      {
          var attributes = HtmlHelper.AnonymousObjectToHtmlAttributes(htmlAttributes);
          builder.MergeAttributes(attributes);
      }
      #endregion
  
      MvcHtmlString retHtml = new MvcHtmlString(builder.ToString(TagRenderMode.SelfClosing));
      return retHtml;
  
    }
  }
  

• Usage in CSHTML:

  @Html.LabelForCamelCase(m=>m.YourPropertyName, new { style="color:red"})
  

  Your shortcut will appear as "Your Property Name"

2. :

[Display(Name = "PropertyKeyAsperResourceFile", ResourceType = typeof(ResourceFileName))]
public string myProperty { get; set; }
