控件：工具栏菜单栏

 

namespace WorkTime
...{
    public partial class Form1 : Form
    ...{
        private string workTime;
        public Form1()
        ...{
            InitializeComponent();
        }
        public string MyWorkTime
        ...{
            set
            ...{
                workTime = value;
            }
            get
            ...{
                return workTime;
            }
        }

        private void button1_Click(object sender, EventArgs e)
        ...{
            Form1 test = new Form1();
            test.MyWorkTime = "我的工作时间是" + this.textBox1.Text;
            this.label1.Text = test.MyWorkTime;
        }
    }
}

上例是有一个可以在区域中填写内容，按下按钮后就可以显示出来。

linkLabel         键接

linkLabel1_LinkClicked

System.Diagnostics.Process.Start("http://www.baidu.com");
-----------------------------------------------------------------------------------

退出

this.Close();

--------------------------
ALT+快捷方式
(&字母)

按ALT可以跳到menuStrip上去

--------------------------
组合键
ALT   SHIFT   CTRL
ShortcutKeys   设置为True   并可以选择.

-------------------------------------------------------------------------------------
在toolStrip中，
按钮有按下去的效果:CheckOnClick  选为True

-------------------------------------------------------------------------------------
ComboBox可以有下拉菜单的效果
   选Items 并在里面加内容.

   事件 SelectedIndexChanged

---------------------------------------------------------------------------------------
richTextBox
  提供一个可以输写文字的空间。
----------------------------------------------------------------------------------------
从现有的label1中的字体创建新的字体,myFontStyle是一个FontStyle枚举:
Bold 加粗文本
Italic 倾斜文本
Regular 普通文本
Strikeout 中间有直线通过的文本
Underline 带下划线的文本
这些值,用二进制表示的,有可能是00001,00010,00100,01000,10000
这样,就可以用二进制运算符对其进行运算了
如果myFontStyle = Bold | Italic,
myFontStyle = 00001|00010
那么,得到的结果将会是00011,右数第一位第二位都是一,表示,字体即是Blod,也是Italic,即粗的斜体.
如果myFontStyle = Bold | Italic.这里是粗斜体.
如果我想除掉斜体呢,那么
myFontStyle=myFontStyle &(~FontStyle.Italic );
即myFontStyle=00011 & (~00010)
=00011 & 11101
=00001
这样,刚好通过00010将00011的右数第二位变成0了.

附注:
|表示"或", 1|1=1,1|0=1,0|1=1,0|0=0
&表示"与", 1|1=1,1&0=0,0&1=0,0&0=0
~表示"反", ~1=0,~0=1,~00010=11101逐位求反
----------------------------------------------------------------------------------------
click事件   里面要带参数

Font newfont;
            Font oldfont;
            oldfont = this.richTextBox1.SelectionFont;
            bool checkState = ((ToolStripButton)sender).Checked;
            if(checkState && !oldfont.Bold)
            {
                newfont = new Font(oldfont, oldfont.Style | FontStyle.Bold);
            }
            else
            {
                newfont = new Font(oldfont, oldfont.Style & ~FontStyle.Bold);   
            }
            this.richTextBox1.SelectionFont=newfont;
            this.richTextBox1.Focus();
----------------------------------------------------------------------------------
----------------------------------------------------------------------------------

CheckedChanged   重点区分啊！

this.toolStripButton1.Checked=this.boldToolStripMenuItem.Checked;

---------------------------------------------------------------------------------

下面代码是一个文字编辑
