Splitting CamelCase

Question

This is all asp.net c#.

I have an enum

public enum ControlSelectionType  {     NotApplicable = 1,     SingleSelectRadioButtons = 2,     SingleSelectDropDownList = 3,     MultiSelectCheckBox = 4,     MultiSelectListBox = 5 } 

The numerical value of this is stored in my database. I display this value in a datagrid.

<asp:boundcolumn datafield="ControlSelectionTypeId" headertext="Control Type"></asp:boundcolumn> 

The ID means nothing to a user so I have changed the boundcolumn to a template column with the following.

<asp:TemplateColumn>     <ItemTemplate>         <%# Enum.Parse(typeof(ControlSelectionType), DataBinder.Eval(Container.DataItem, "ControlSelectionTypeId").ToString()).ToString()%>     </ItemTemplate> </asp:TemplateColumn> 

This is a lot better... However, it would be great if there was a simple function I can put around the Enum to split it by Camel case so that the words wrap nicely in the datagrid.

Note: I am fully aware that there are better ways of doing all this. This screen is purely used internally and I just want a quick hack in place to display it a little better.

Answer 1

I used:

    public static string SplitCamelCase(string input)     {         return System.Text.RegularExpressions.Regex.Replace(input, "([A-Z])", " $1", System.Text.RegularExpressions.RegexOptions.Compiled).Trim();     }

vb.net:

Public Shared Function SplitCamelCase(ByVal input As String) As String     Return System.Text.RegularExpressions.Regex.Replace(input, "([A-Z])", " $1", System.Text.RegularExpressions.RegexOptions.Compiled).Trim() End Function 

Answer 2

Indeed a regex/replace is the way to go as described in the other answer, however this might also be of use to you if you wanted to go a different direction

    using System.ComponentModel;     using System.Reflection; 

...

    public static string GetDescription(System.Enum value)     {         FieldInfo fi = value.GetType().GetField(value.ToString());         DescriptionAttribute[] attributes = (DescriptionAttribute[])fi.GetCustomAttributes(typeof(DescriptionAttribute), false);         if (attributes.Length > 0)             return attributes[0].Description;         else             return value.ToString();     } 

this will allow you define your Enums as

public enum ControlSelectionType  {     [Description("Not Applicable")]     NotApplicable = 1,     [Description("Single Select Radio Buttons")]     SingleSelectRadioButtons = 2,     [Description("Completely Different Display Text")]     SingleSelectDropDownList = 3, }
