C#实现简单文本编辑器

本文实例为大家分享了c#实现简单文本编辑器的具体代码，供大家参考，具体内容如下

建立一个窗体文件，实现对文件的编辑保存和对txt文件的打开

界面设计：

程序源代码：

//form1.cs
using system;
using system.collections.generic;
using system.componentmodel;
using system.data;
using system.drawing;
using system.linq;
using system.text;
using system.threading.tasks;
using system.windows.forms;

namespace txt_editapp
{
 public partial class form1 : form
 {
  public form1()
  {
   initializecomponent();
  }
  //open file 菜单选项
  private void openfiletoolstripmenuitem_click(object sender, eventargs e)
  {
   openfiledialog1.filter = "txt files(*.txt)|*.txt";
   if(openfiledialog1.showdialog()==dialogresult.ok)
   {
    richtextbox1.loadfile(openfiledialog1.filename, richtextboxstreamtype.plaintext);
   }
  }
  //save file 菜单选项
  private void savefiletoolstripmenuitem_click(object sender, eventargs e)
  {
   savefiledialog1.filter = "txt files(*.txt)|*.txt";
   if(savefiledialog1.showdialog()==dialogresult.ok)
   {
    richtextbox1.savefile(savefiledialog1.filename, richtextboxstreamtype.plaintext);
   }
  }
  //exit file 菜单选项
  private void exittoolstripmenuitem_click(object sender, eventargs e)
  {
   close();
  }
  //about 菜单选项
  private void abouttoolstripmenuitem_click(object sender, eventargs e)
  {
   form2 frm = new form2();
   frm.showdialog();
  }
 }
}


//form2.cs
using system;
using system.collections.generic;
using system.componentmodel;
using system.data;
using system.drawing;
using system.linq;
using system.text;
using system.threading.tasks;
using system.windows.forms;

namespace txt_editapp
{
 public partial class form2 : form
 {
  public form2()
  {
   initializecomponent();
  }

  private void label2_click(object sender, eventargs e)
  {

  }
 }
}
