Get hex color from Drawing.Color

Question

Hello

Dim Col As Color = Color.FromArgb(Red * 255, Green * 255, Blue * 255)

Now I have Col, how should I convert it to hex color to insert in html pages?

It is expected to be in a format like: #0b7ed9

Col.ToArgb.ToString("X6") and .ToArgb.ToString("X") will return something like FFA142CC which is not valid for html pages.

Any tips?

Thanks :)

There is a built-in method just for this.

        Dim someColor As Color = Color.LightCoral
        Dim htmlColor As String = System.Drawing.ColorTranslator.ToHtml(Color.FromArgb(someColor.ToArgb()))

Hi @Peter Volz ,

You can get the hex data for each color channel individually and combine it.

You can refer to the following code.

    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        Dim Col As Color = Color.FromArgb(255, 255, 255)
        Dim hexColor As String = ColorToHex(Col)
        Console.WriteLine(hexColor) ' Output: #FF0000
    End Su

    Public Function ColorToHex(color As Color) As String
        Return "#" & color.R.ToString("X2") & color.G.ToString("X2") & color.B.ToString("X2")
    End Function

Best Regards.
