C#实现文件管理器—by henryqin
2009-04-04 08:22:43 来源：WEB开发网//上下文菜单项
ContextMenuStrip1.Items.Add(msEditNew);
ContextMenuStrip1.Items.Add(msEditBar1);
ContextMenuStrip1.Items.Add(msEditCut);
ContextMenuStrip1.Items.Add(msEditPaste);
ContextMenuStrip1.Items.Add(msEditDelete);
ContextMenuStrip1.Items.Add(msEditBar2);
这样就OK了，你在目标控件上按右键时将弹出快捷菜单。
通过上面的介绍，大家应该能明白本例中要实现的效果，需要用到的控件及重要属性等，下面，就可以切入正题，如何通过编程，实现我们上面提到的功能。呵呵，再提一点，也是比较重要的：C#是一种面向对象的编程语言，因此，在编程之前我们就要有“面向对象编程”的思想，在编程的过程中贯彻这样的思想，
同时，这也是符合目前公司里的编程思想。还有一点，尽量做到代码的规范，可以为以后再次开发或别人阅读我们程序起到简便明了的作用。
主要有两个类：Folder.cs和Txt.cs，分别是对文件和文本的相关操作。类里的方法，我都做了详尽的注释，如果还有什么不明白，可以联系我。

//如果输入信息为空，提示
if (foldername == "")
{
MessageBox.Show("目录名不能为空");
return;
}
else
{
string FullName = path + "" + foldername;
//如果该文件以及存在
if (Directory.Exists(FullName))
{
MessageBox.Show("该目录已经存在，请重命名");
