16进制字符串转为数字

左直拳

Conver.ToInt32(“0xAB”,16);

所以在代码里给控件赋颜色值，可以这样：

public string
    {
  
        set
   
        {
  
             //value = #ab364f
   
            int r = Convert.ToInt32("0x" + value.Substring(1, 2),16);
  
            int g = Convert.ToInt32("0x" + value.Substring(3, 2),16);
  
            int b = Convert.ToInt32("0x" + value.Substring(5, 2),16);
  
            txtUrl.ForeColor = System.Drawing.Color.FromArgb(r,g,b);
  
        }
  
 }
