Question

我不太确定我是愚蠢的。什么是Web调色板小部件调用？ colordialog带来了另一个不是我想要的选择器

我看网络，但大多数调色板没有网页选择器。提前致谢 [编辑：也许我应该重新解释这个问题，我如何提出上面的颜色选择器？我不想使用任何第三方小部件，除了那些已经在VS]

中可用的小部件

我希望有人想出一个开箱即用的.Net解决方案。

如果没有，你可以写自己的;这是一个初学者..：

public partial class WebColors : Form
{
    public WebColors()
    {
        InitializeComponent();
    }

    public Color pick { get; set; }

    private void WebColors_Load(object sender, EventArgs e)
    {
        var webColors =
          Enum.GetValues(typeof(KnownColor))
            .Cast<KnownColor>()
            .Where(k => k >= KnownColor.Transparent && k < KnownColor.ButtonFace)
            .Select(k => Color.FromKnownColor(k))
            .OrderBy(c => c.GetHue())
            .ThenBy(c => c.GetSaturation())
            .ThenBy(c => c.GetBrightness()).ToList();

        int cc = webColors.Count;
        int n =  (int)Math.Sqrt(cc) + 0;
        int w = ClientSize.Width / (n) - 1;
        Height = (n+1) * w + 90;
        for (int i = 0; i < cc; i++)
        {
            Label lbl = new Label();
            lbl.Text = "";
            lbl.AutoSize = false;
            lbl.Size = new Size(w - 1, w - 1);
            lbl.BackColor = webColors[i];
            lbl.BorderStyle = BorderStyle.FixedSingle;
            lbl.Location = new Point(1 +  w * (i  % (n+ 1)) , w * ( i / (n+1)) );
            lbl.Click += (ss, ee) =>
            {
                pick = lbl.BackColor;
                lbl_colorName.Text = pick.Name;
            };
            Controls.Add(lbl);
        }

    }

    private void cb_ok_Click(object sender, EventArgs e)
    {
        this.DialogResult = DialogResult.OK;
        this.Close();
    }

    private void cb_cancel_Click(object sender, EventArgs e)
    {
        this.Close();
    }
}

您可以添加排序选项并切换orderby子句..

您可以使用rgb颜色

your_object_here.BackColor = Color.FromArgb(255, 210, 210); 
your_object_here.ForeColor = Color.FromArgb(255,255,255);
