C# 抓取資料夾檔案資訊存放在DataTable，並將檔案複製到其他位置

抓取資料夾檔案資訊存放在DataTable

        DataTable DT = new DataTable();
        DT.Columns.Add("FullName");

        foreach (string fname in System.IO.Directory.GetFileSystemEntries("D:\\WWW"))
        {
            if (fname.IndexOf(".doc") > 0 || fname.IndexOf(".docx") > 0)
            {
                DT.Rows.Add(fname);
            }
        }

        GridView1.DataSource = DT;
        GridView1.DataBind();

抓取資料夾完整檔案資訊存放在DataTable

        DataTable DT = new DataTable();
        DT.Columns.Add("Sno");
        DT.Columns.Add("Name");
        DT.Columns.Add("FullName");
        DT.Columns.Add("Extension");
        DT.Columns.Add("Length");
        DT.Columns.Add("Attributes");
        DT.Columns.Add("CreationTime");
        DT.Columns.Add("LastAccessTime");
        DT.Columns.Add("LastWriteTime");
        DT.Columns.Add("Directory");

        int Sno = 1;
        foreach (string FilePathName in System.IO.Directory.GetFileSystemEntries("D:\\WWW", "*.doc"))
        {
            //FileInfo 請 using System.IO;
            FileInfo theFile;
            theFile = new FileInfo(FilePathName);

            if (theFile.Exists)
            {
                DT.Rows.Add(Sno, theFile.Name, theFile.FullName, theFile.Extension, theFile.Length, theFile.Attributes.ToString(), theFile.CreationTime, theFile.LastAccessTime, theFile.LastWriteTime, theFile.Directory);
                Sno = Sno + 1;
            }
        }

        GridView2.DataSource = DT;
        GridView2.DataBind();

抓取資料夾MP3檔案資訊，並透過WindowsMediaPlayer抓取檔案資訊，存放在DataTable

        if (FileUpload1.PostedFile.ContentLength > 0)
        {
            DataTable DT = new DataTable();
            DT.Columns.Add("Sno");
            DT.Columns.Add("Name");
            DT.Columns.Add("FullName");
            DT.Columns.Add("Extension");
            DT.Columns.Add("Directory");
            DT.Columns.Add("Length");
            DT.Columns.Add("出版商");
            DT.Columns.Add("演唱者");
            DT.Columns.Add("歌曲名稱");
            

            foreach (string FilePathName in System.IO.Directory.GetFileSystemEntries(FileUpload1.PostedFile.FileName.Replace(FileUpload1.FileName, "")))
            {
                if (FilePathName.IndexOf(".mp3") > 0 || FilePathName.IndexOf(".wma") > 0)
                {
                    //FileInfo 請 using System.IO;
                    FileInfo theFile;
                    theFile = new FileInfo(FilePathName);

                    if (theFile.Exists)
                    {
                        WMPLib.WindowsMediaPlayer wmp = new WMPLib.WindowsMediaPlayer();
                        wmp.settings.mute = true;
                        wmp.URL = theFile.FullName;
                        wmp.controls.play();
                        System.Threading.Thread.Sleep(100);

                        DT.Rows.Add(theFile.Name.Substring(0, 2), theFile.Name, theFile.FullName, theFile.Extension, theFile.Directory, theFile.Length, wmp.currentMedia.getItemInfo("Author"), wmp.currentMedia.getItemInfo("Artist"), wmp.currentMedia.getItemInfo("Title"));
                        
                        wmp.close();
                    }
                }
            }

            GridView2.DataSource = DT;
            GridView2.DataBind();
        }

將抓取到的資料檔案，複製檔案到其他位置(路徑)

        for (int i = 0; i < GridView2.Rows.Count; i++)
        {
            //原始檔案資料夾 
            String SourcePath = GridView2.Rows[i].Cells[9].Text + "\\" + GridView2.Rows[i].Cells[1].Text;
            //要移至的檔案資料夾 
            String MoveToPath = "D:\\WWW\\" + GridView2.Rows[i].Cells[1].Text;

            if (File.Exists(SourcePath))
            {
                File.Copy(SourcePath, MoveToPath, true);
            }
        }

        for (int i = 0; i < GridView2.Rows.Count; i++)
        {
            //原始檔案資料夾 
            String SourcePath = GridView2.Rows[i].Cells[9].Text + "\\" + GridView2.Rows[i].Cells[1].Text;
            //要移至的檔案資料夾 
            String MoveToPath = "/RaWMroot/" + GridView2.Rows[i].Cells[1].Text;

            if (File.Exists(SourcePath))
            {
                File.Copy(SourcePath, Server.MapPath(MoveToPath), true);
            }
        }

抓取上傳檔案完整路徑及名稱

Label1.Text = FileUpload1.PostedFile.FileName;

抓取上傳檔案路徑

Label1.Text = FileUpload1.PostedFile.FileName.Replace(FileUpload1.FileName, "");
