我想在 aspx.CS 后台中写：this.TextBox1.BackColor = "#006030 "; 为什么报错， 可是在aspx 页中就正常啊
------解决方案--------------------------------------------------------
this.TextBox1.BackColor = System.Drawing.ColorTranslator.FromHtml( "#006030 ");需要一个Color对象
------解决方案--------------------------------------------------------
using System.Drawing;
this.TextBox1.BackColor = ColorTranslator.FromHtml( "#006030 ");
------解决方案--------------------------------------------------------
别忘了引用:System.Drawing
