SL将颜色名称转换为颜色值的简单方法（以前提过无人给出好答案，现用反射快速解决）。

Question

        /// <summary>
        /// 根据颜色名称字符串得到颜色值
        /// </summary>
        /// <param name="ColorNameStr">
        /// 颜色名称字符串,可以是标准的或Window系统已定义的颜色字符串名称。
        /// 如: White,Black ..., ActiveCaptionColor, ActiveBorderColor 等
        /// </param>
        /// <returns></returns>
        public static Color FromNameColor(string ColorName)
        {
            ColorName = (ColorName + "").ToUpper();
            var Lnq1 = from X in (typeof(Colors)).GetProperties()
                       let ClrN = X.Name.ToUpper()
                       let ClrV = (Color)X.GetValue(X, null)
                       where (ClrN == ColorName)
                       select ClrV;
            var Lnq2 = from X in (typeof(SystemColors)).GetProperties()
                       let ClrN = X.Name.ToUpper()
                       let ClrV = (Color)X.GetValue(X, null)
                       where (ClrN == ColorName)
                       select ClrV;
            var Lnq = Lnq1.Concat(Lnq2);
            return Lnq.Count() <= 0 ? Colors.White : (Color)Lnq.First();
        }
