颜色选择器的设计与实现

通过颜色选择器可以简单的获得喜欢颜色的RGB值。

实现步骤：

1、拖拽picturebox，HScrollBar控件和TextBox；

2、为HScrollBar的滚动事件添加事件处理程序如下：

private void hScrollBar3_Scroll(object sender, System.Windows.Forms.ScrollEventArgs e)
         {
              this.textBox1.Text = this.hScrollBar1.Value.ToString();
              this.textBox2.Text = this.hScrollBar2.Value.ToString();
              this.textBox3.Text = this.hScrollBar3.Value.ToString();
              this.pictureBox1.BackColor = Color.FromArgb(this.hScrollBar1.Value,this.hScrollBar2.Value,this.hScrollBar3.Value);
      }
3、         为textBox1、textBox2、textBox3添加的TextChanged事件处理程序如下：
privatevoid textBox1_TextChanged(object
      {
try
        {
int i = Convert.ToInt32(this.textBox1.Text);
int j = Convert.ToInt32(this.textBox2.Text);
int k = Convert.ToInt32(this.textBox3.Text);
if(((i <= 255)&&(i>=0))&&((j <= 255)&&(j>=0))&&((k <= 255)&&(k>=0)))
           {
this.hScrollBar1.Value = i;
this.hScrollBar2.Value = j;
this.hScrollBar3.Value = k;
this.pictureBox1.BackColor = Color.FromArgb(this.hScrollBar1.Value,this.hScrollBar2.Value,this.hScrollBar3.Value);
   
           }
        }
catch
        {
        }
      }
   3、其它代码见清单
