I know I can use the following code get pre-defined color name one by one, how can I get all system color names? I can't find a system color name collection

System.Drawing.Color.LightSalmon

Here's how to get the names and colors (you can fill the dropdownlistbox)

 

        System.Drawing.Color MyColor;
        foreach (string ColorName in Enum.GetNames(typeof(System.Drawing.KnownColor)))
        {
            Response.Write(ColorName + "<br />");
            MyColor = System.Drawing.Color.FromName(ColorName);
        }

 Looks an interesting way to get a colout list and tried

        this.GridColour.DataSource = Enum.GetNames(typeof(System.Drawing.KnownColor));
        this.GridColour.DataBind();

where (absolute size put in to restrict column width)

         <asp:GridView ID="GridColour" runat="server" Width="200px">
        </asp:GridView>

and gave the following list - manifestly not all are colours!

Yeah, the list includes the "System Colors" (ie the color of a ButtonFace, MenuBar).  These are the colors that the user can change from the control panel.

Here's a version that filters out the system colors:

    protected void Button1_Click(object sender, EventArgs e)
    {
        System.Drawing.Color MyColor;
        foreach (string ColorName in Enum.GetNames(typeof(System.Drawing.KnownColor)))
        {          
            MyColor = System.Drawing.Color.FromName(ColorName);
            if (MyColor.IsSystemColor == true)
                continue;
            Response.Write(ColorName + "<br />");
        }            
    }
