Answer 2

            Color _Color = Color.FromArgb(Convert.ToInt32("FF"+"#FFFFFF".Remove(0, 1), 16));
            MessageBox.Show(GetColorName(_Color));         
            
        }
        public string GetColorName(Color p_Color)
        {
            PropertyInfo [] _PropertyList = typeof(Color).GetProperties(BindingFlags.Public | BindingFlags.Static);
            Color _ValueColor;
            for (int i = 0; i != _PropertyList.Length; i++)
            {
                _ValueColor =(Color) _PropertyList[i].GetValue(null, null);
                if (_ValueColor.R == p_Color.R && _ValueColor.G == p_Color.G && _ValueColor.B == p_Color.B && _ValueColor.A ==p_Color.A)
                {
                    return _PropertyList[i].Name;
                }
            }            return "";
        }

Answer 3

4楼的程序不错，我测试了一下：
using System;
using System.Drawing;
using System.Reflection;class Program
{
  static void Main()
  {
    foreach (KnownColor k in Enum.GetValues(typeof(KnownColor)))
    {
      Color c = Color.FromKnownColor(k);
      Console.WriteLine("{0,3} {1,25} {2:x8} {3}", (int)k, k, c.ToArgb(), GetColorName(c));
    }
  }  public static string GetColorName(Color p_Color) 
  { 
    PropertyInfo[] _PropertyList = typeof(Color).GetProperties(BindingFlags.Public | BindingFlags.Static); 
    for (int i = 0; i != _PropertyList.Length; i++) 
    { 
      Color _ValueColor = (Color)_PropertyList[i].GetValue(null, null); 
      if (_ValueColor.ToArgb() == p_Color.ToArgb())
      { 
        return _ValueColor.Name; 
      } 
    } 
    return ""; 
  } 
}

Answer 4

这个方法我已经用过了，有的rgb没有转换过来 如#4B1156 这种的，而且循环好多次，效率很低啊~~  还有什么解决的办法不~~

Answer 5

            Console.WriteLine(ColorTranslator.FromHtml("#4B1156"));

Answer 6

你要清楚一点...不是每种RGB颜色都有名字的，4楼代码出的那些名字也只是Windows系统的预定义的名称，没有定义的当然没有...你只有自己写个对照表，否则系统没有与定义名称的鬼才知道叫什么...
