C#顏色對話框（WPF可用）

System.Windows.Forms.ColorDialog colorDialog = new System.Windows.Forms.ColorDialog();
//允許使用該對話框的自定義顏色
colorDialog.AllowFullOpen = true;
colorDialog.FullOpen = true;
colorDialog.ShowHelp = true;
//初始化當前文本框中的字體顏色，
colorDialog.Color = System.Drawing.Color.Black;
//當用戶在ColorDialog對話框中點擊"取消"按鈕
colorDialog.ShowDialog();
string strColor=System.Drawing.ColorTranslator.ToHtml(colorDialog.Color);
this.colorBtn.Content = strColor;
