如何实现目录之间的拷贝？

yzh0313 2008-06-11 10:18:51

菜鸟有几个问题在此请教各位大虾：

用C#与VS2002开发Winform系统.

1. 如何实现目录之间的拷贝.
也就是将一目录下所有的文件和子目录拷贝至另外一目录下.在VS2005中好象有CopyDirectory()方法实现如上功能,但在VS2002中无此方法,请问这种情况下应该如何实现所述功能.

2. 如何获取路径.
目的:实现文件的拷贝,将源路径下的文件拷贝至目标路径,要求将目标路径写进INI配置文件中,且目标路径由用户自己来选择,不能在文本框中直接输入目标路径,而是希望通过例如保存文件一样的对话框来选择所需之路径,该如何实现?

3.通过相对路径如何获得绝对路径.
在ASP.NET中曾经用过Server.MapPath("文件名")方式来获取文件的绝对路径,不知道在VS2002中开发WinForm系统该如何实现.

用FileUpload.SaveAs不知道VS2002有沒有這個方法

string name = FileUpload1.PostedFile.FileName;
FileInfo file = new FileInfo(name);
string fileName = file.Name;
webFilePath = Server.MapPath("Photo/" + fileName);
src = "Photo/" + fileName;
FileUpload1.SaveAs(webFilePath);
Image1.ImageUrl = src;
FileStream fs;
fs = File.OpenRead("" + webFilePath + "");
byte[] imagedata = new byte[fs.Length];
int count = (int)fs.Length;
fs.Read(imagedata, 0, count);
Conn.Open();
StrSql = "update product set imagedata=@imagedata,src=@src where pid='" + pid + "'";
cmd = new SqlCommand(StrSql, Conn);
cmd.Parameters.AddWithValue("@imagedata", imagedata);
cmd.Parameters.AddWithValue("@src", src);

目标拷贝
using System.IO;

               private static void CopyDirectory(DirectoryInfo OldDirectory, DirectoryInfo NewDirectory)

                {

                        string NewDirectoryFullName = NewDirectory.FullName + @"\" + OldDirectory.Name;



                        if ( !Directory.Exists(NewDirectoryFullName) )

                                Directory.CreateDirectory(NewDirectoryFullName);

                        

                        FileInfo[] OldFileAry = OldDirectory.GetFiles();

                        foreach (FileInfo aFile in OldFileAry) 

                                File.Copy(aFile.FullName, NewDirectoryFullName +  @"\" +  aFile.Name, true);



                        DirectoryInfo[]        OldDirectoryAry = OldDirectory.GetDirectories();

                        foreach ( DirectoryInfo aOldDirectory in OldDirectoryAry )

                        {

                                DirectoryInfo aNewDirectory = new DirectoryInfo(NewDirectoryFullName);

                                CopyDirectory(aOldDirectory, aNewDirectory);

                        }

                }



                //CopyDirectory

                public static void CopyDirectory(string OldDirectoryStr, string NewDirectoryStr)

                {

                        DirectoryInfo OldDirectory = new DirectoryInfo( OldDirectoryStr );

                        DirectoryInfo NewDirectory = new DirectoryInfo( NewDirectoryStr );        

                        FileExec.CopyDirectory(OldDirectory,NewDirectory);

                }
