  • C# 设置应用程序背景颜色
    C# 设置应用程序背景颜色,通过调用Windows调色板,来选取颜色,然后程序将颜色值赋值给窗口,此盒子可设置斜体的颜色值,运行效果如参考截图所示,核心代码请看以下代码片段:   private void Form1_Load(object sender, EventArgs e)   {//显示应用程序背景颜色    //先打开“Properties”,添加一个System.Drawing.Color类型的变量MyBackColor    this.BackColor = Properties.Settings.Default.MyBackColor;   }   private void button1_Click(object sender, EventArgs e)   {//设置应用程序背景颜色(在运行时编写用户设置)    if(this.colorDialog1.ShowDialog()==DialogResult.OK)    {    Properties.Settings.Default.MyBackColor = this.colorDialog1.Color;    Properties.Settings.Default.Save();    this.BackColor = Properties.Settings.Default.MyBackColor;    }   }
