C#里16进制字符串转为数字

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 ForeColor

    {

        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);

        }

 }
