哪个类可以实现文件的拷贝，粘贴，覆盖粘贴等功能

gz

是ClipBoard
比如有个menu_cut,menu_copy,menu_paste菜单
void menu_cut_click(object obj,EventArgs ea){
menu_copy_click(obj,ea);
str=""; //实现剪贴效果
}
void menu_copy_click(object obj,EventArgs ea){
Clipboard.SetDataObject(str,true); //设置剪贴板
}
void menu_paste_click(object obj,EventArgs ea){
IDataObject data=Clipboard.GetDataObject();
if(data.GetDataPresent(typeof(string))) //判断剪贴板中是否有string
str=(string)data.GetData(typeof(string));
}


wish u good luck

System.IO.FileInfo
System.IO

不知道要的是不是这个

[哈哈007哈]

shuhill(蜀山幽狼) ：能具体点吗！，谢谢

[vcshcn]

file

[chenyuming2004]

System.File类
里面有
Copy()
方法实现文件复制。

[haveaquestion]

[C#]
public static void Copy(
string sourceFileName,
string destFileName
);

[coudoufu]

ClipBoard
实现复制、粘贴、剪切这个比较好

[shuhill]

System.IO .File.Copy(源文件名,目录文件名,是否Overwrite); '拷贝
System.IO.File.Delete(文件名); '删除
