如何用c#.net编写记事本，全代码，请高手指点一下！

Answer 1

记事本总得来讲不难，，
记事本不外乎就打开、保存、复制、剪切、粘贴等几项主要功能，

我都给你写写

OpenFileDialog ofd = new OpenFileDialog();
ofd.Filter = "基本格式|*.txt;*.doc";
ofd.RestoreDirectory = false;
if (ofd.ShowDialog() == DialogResult.OK)
{
using (FileStream fs = new FileStream(ofd.FileName,FileMode.Open,FileAccess.Read))
{
StreamReader sr = new StreamReader(fs, Encoding.Default);
textBox1.Text = sr.ReadToEnd();
}

}
———————————————打开代码—————————————————
SaveFileDialog sfd = new SaveFileDialog();
sfd.RestoreDirectory = false;
sfd.Filter = "文本格式|*.txt";
if (sfd.ShowDialog() == DialogResult.OK)
{
using (FileStream fs = new FileStream(sfd.FileName, FileMode.Create, FileAccess.Write))
{
StreamWriter sw = new StreamWriter(fs, Encoding.Default);
sw.Write(textBox1.Text);
sw.Flush();
sw.Close();

}
}
———————————————保存代码—————————————————
textBox1.Copy();
textBox1.Cut();
textBox1.Paste();
等等很多，详细你可以自己去看看
