C#编写记事本（高仿）
近一周写的关于记事本的代码，高仿记事本。本人C#入门不久，其中存在代码冗余，但懒得修改了。
经测试运行正常。
一、主窗体设计及代码
namespace BestEditor
{
public partial class Main : Form
{
private bool isTextChanged;
private string path;//记录文件路径（刚新建的文件路径为""，打开的文件路径为原路径） public Main()
{
InitializeComponent();
this.Text = "无标题 - 记事本";
path = "";
} /// <summary>
/// 初始化窗体时调用
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void Main_Load(object sender, EventArgs e)
{
//初始化，撤销、剪切、复制、删除 不可用
撤消UToolStripMenuItem.Enabled = false;
剪切TToolStripMenuItem.Enabled = false;
复制CToolStripMenuItem.Enabled = false;
删除LToolStripMenuItem.Enabled = false; if (richTextBoxBoard.Equals(""))
{
查找FToolStripMenuItem.Enabled = false;
查找下一个NToolStripMenuItem.Enabled = false;
}
else
{
查找FToolStripMenuItem.Enabled = true;
查找下一个NToolStripMenuItem.Enabled = true;
} if (Clipboard.ContainsText())
粘贴PToolStripMenuItem.Enabled = true;
else
粘贴PToolStripMenuItem.Enabled = false; toolStripStatusLabel2.Text = "第 1 行，第 1 列";
} private void 新建NToolStripMenuItem_Click(object sender, EventArgs e)
{
//如果输入框文字发生变动
if (isTextChanged)
{
saveFileDialog1.FileName = "*.txt";
DialogResult dr = MessageBox.Show("是否将更改保存到 " + this.Text + "?", "记事本",
MessageBoxButtons.YesNoCancel);
if (dr == DialogResult.Yes)
{
//获取或设置指定要在 SaveFileDialog 中显示的文件类型和说明的筛选器字符串

}
}
}
}
}
二、查找子窗体设计及代码
namespace BestEditor
{
public partial class Search : Form
{
private RichTextBox rtb = new RichTextBox(); public Search()
{
InitializeComponent();
} /// <summary>
/// 初始化时得到主窗口的通讯数据
/// </summary>
/// <param name="sender"></param>

private void Search_Load(object sender, EventArgs e)
{
Main main = (Main)this.Owner;
this.rtb = main.richTextBoxBoard;
} /// <summary>
/// 取消
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void button2_Click(object sender, EventArgs e)
{
this.Close();
} private void button1_Click(object sender, EventArgs e)
{
string str = rtb.Text;//文件内容
string subSearch = textBox1.Text;//查找内容
string initString = subSearch;
int pos = rtb.SelectionStart;//光标位置 if (!checkBox1.Checked)
{
str = str.ToLower();
subSearch = subSearch.ToLower();
} if (radioButton1.Checked)//向上查找
{
if (rtb.SelectionLength > )
pos = pos + rtb.SelectionLength - ; str = str.Substring(, pos);
if (subSearch != "" && (pos = str.LastIndexOf(subSearch, pos)) != -)
{
//输入框得到焦点并选中查找的内容
rtb.Focus();
rtb.SelectionStart = pos;
rtb.SelectionLength = subSearch.Length;
}
else
MessageBox.Show("找不到\"" + initString + "\"", "记事本",
MessageBoxButtons.OK, MessageBoxIcon.Information);
}
else
{
if (rtb.SelectionLength > )
pos = pos + ;
if (subSearch != "" && (pos = str.IndexOf(subSearch, pos)) != -)
{
rtb.Focus();
rtb.SelectionStart = pos;
rtb.SelectionLength = subSearch.Length;
}
else
MessageBox.Show("找不到\"" + subSearch + "\"", "记事本",
MessageBoxButtons.OK, MessageBoxIcon.Information);
}
}
}
}
三、替换子窗体设计及其代码
namespace BestEditor
{
public partial class Change : Form
{
private RichTextBox rtb = new RichTextBox(); public Change()
{
InitializeComponent();
} private void Change_Load(object sender, EventArgs e)
{
Main main = (Main)this.Owner;
this.rtb = main.richTextBoxBoard;
button1.Enabled = false;
button2.Enabled = false;
button3.Enabled = false;
} /// <summary>
/// 查找下一个
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void button1_Click(object sender, EventArgs e)
{
string str = rtb.Text;
string subSearch = textBox1.Text;
string initString = subSearch;
int pos = rtb.SelectionStart; if (!checkBox1.Checked)
{
str = str.ToLower();
subSearch = subSearch.ToLower();
} if (rtb.SelectionLength > )
pos = pos + ;
if ((pos = str.IndexOf(subSearch, pos)) != -)
{
rtb.Focus();
rtb.SelectionStart = pos;
rtb.SelectionLength = subSearch.Length;
}
else
MessageBox.Show("找不到\"" + initString + "\"", "记事本",
MessageBoxButtons.OK, MessageBoxIcon.Information);
} private void textBox1_TextChanged(object sender, EventArgs e)
{
bool flag = textBox1.Text != "";
button1.Enabled = flag;
button2.Enabled = flag;
button3.Enabled = flag;
} /// <summary>
/// 取消
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void button4_Click(object sender, EventArgs e)
{
this.Close();
} /// <summary>
/// 替换
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void button2_Click(object sender, EventArgs e)
{
string str = rtb.Text;
string subSearch = textBox1.Text;
string initString = subSearch;
string changeTo = textBox2.Text;
string front;
string dest;
string back;
int pos = rtb.SelectionStart; if (!checkBox1.Checked)
{
str = str.ToLower();
subSearch = subSearch.ToLower();
} if (rtb.SelectionLength > )
{
if (rtb.SelectedText.Equals(subSearch))
{
//将文本框字符串分段，替换后再组合
front = rtb.Text.Substring(,pos);
dest = changeTo;
back = rtb.Text.Substring(pos + subSearch.Length, rtb.Text.Length - pos - subSearch.Length);
rtb.Text = front + dest + back;
}
pos = pos + ;
} if ((pos = str.IndexOf(subSearch, pos)) != -)
{
rtb.Focus();
rtb.SelectionStart = pos;
rtb.SelectionLength = subSearch.Length;
}
else
MessageBox.Show("找不到\"" + initString + "\"", "记事本",
MessageBoxButtons.OK, MessageBoxIcon.Information);
} /// <summary>
/// 全部替换
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void button3_Click(object sender, EventArgs e)
{
string str = rtb.Text;
string subSearch = textBox1.Text;
string changeTo = textBox2.Text;
string front;
string dest;
string back;
int pos = ; if (!checkBox1.Checked)
{
str = str.ToLower();
subSearch = subSearch.ToLower();
} while ((pos=str.IndexOf(subSearch,pos))!=-)
{
front = rtb.Text.Substring(, pos);
dest = changeTo;
back = rtb.Text.Substring(pos + subSearch.Length, rtb.Text.Length - pos - subSearch.Length);
rtb.Text = front + dest + back;
if (!checkBox1.Checked)
str = rtb.Text.ToLower();
}
}
}
}
四、转到子窗体设计及其代码
namespace BestEditor
{
public partial class Goto : Form
{
private RichTextBox rtb = new RichTextBox(); public Goto()
{
InitializeComponent();
} private void Goto_Load(object sender, EventArgs e)
{
Main main = (Main)this.Owner;
this.rtb = main.richTextBoxBoard;
} private void textBox1_KeyPress(object sender, KeyPressEventArgs e)
{
if ((e.KeyChar < || e.KeyChar > ) && e.KeyChar != && e.KeyChar != )
{
e.Handled = true;
MessageBox.Show("只能接收数字","记事本",MessageBoxButtons.OK,MessageBoxIcon.Error);
}
} private void button2_Click(object sender, EventArgs e)
{
this.Close();
} /// <summary>
/// 确定
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void button1_Click(object sender, EventArgs e)
{
int row = int.Parse(textBox1.Text);
int pos = ;
string[] str = rtb.Text.Split('\r', '\n'); if (row < || row > str.Length)
MessageBox.Show("行数超出范围", "记事本 - 跳行", MessageBoxButtons.OK);
else
{
for (int i = ; i < row; i++)
pos = pos + str[i-].Length + ;
this.Close();
rtb.Focus();
rtb.SelectionStart = pos;
}
}
}
}
五、“关于”对话框
直接插入“关于”对话框即可
