Color Chart code which enumerates all the names of the .NET "Color Structure"

  • Article

It often becomes difficult to remember the color names in .NET. Now, if you have a datagrid or any other control and looking for appropriate colors, this code will help you to create a small page which will show you all the colors in one page, along with their names. It uses .NET reflection to get names of all the Color Names in the .NET Color structure.

Here is what the output looks like...

Let's create a new web page in a VB.NET Web project called ColorChart and delete everything in the code behind. Then, paste the following code and run the project with ColorChart as the start page.

Imports System.Reflection
'
Public Class ColorChart
Inherits System.Web.UI.Page
'
#Region " Web Form Designer Generated Code "
'This call is required by the Web Form Designer.
<System.Diagnostics.DebuggerStepThrough()> Private Sub InitializeComponent()
End Sub
Private Sub Page_Init(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Init
'CODEGEN: This method call is required by the Web Form Designer
'Do not modify it using the code editor.
InitializeComponent()
End Sub
#End Region
'
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'
'Put user code to initialize the page here
Response.Write("<Table width='100%' border=1 cellspacing=0 cellpadding=0>")
Response.Write("<TR bgcolor='gray'><TD width='16%'><B>Color Name</TD><TD width='16%'>" & _
"<B>Color</TD><TD width='16%'><B>Color Name</TD><TD width='16%'><B>Color</TD>" & _
"<TD width='16%'><B>Color Name</TD><TD width='16%'><B>Color</TD></TR>")
'
'This is because we want to get the assembly's information
Dim x As Color
Dim strType As Type = x.GetType()
Dim arrMemberInfo() As MemberInfo = strType.GetProperties
Dim myMemberInfo As MemberInfo
'Lets Enumerate the colors now in three columns
Dim i As Integer = 0
Dim Remainder As Integer = 0
For Each myMemberInfo In arrMemberInfo
Remainder = i Mod 3
If Remainder = 0 Then
Response.Write("<TR>")
End If
Response.Write("<TD>" + myMemberInfo.Name + "</TD>")
Response.Write("<TD bgcolor='" + myMemberInfo.Name + _
"' borderColor='black' borderColorLight='black' borderColorDark='black'></TD>")
'
If Remainder = 2 Then
Response.Write("</TR>")
End If
i += 1
If myMemberInfo.Name = "YellowGreen" Then Exit For
Next myMemberInfo
Response.Write("</Table>")
End Sub
End Class

Hope that helps!
