*我这是怎么浏览图片的路径，并显示在FlowLayoutPanel的

private void button1_Click_2(object sender, EventArgs e) 
     { 
      DialogResult dr = this.openFileDialog1.ShowDialog(); 
      if (dr == System.Windows.Forms.DialogResult.OK) 
      { 
       // Read the files 
       foreach (String file in openFileDialog1.FileNames) 
       { 
        // Create a PictureBox. 
        try 
        { 
         Panel panel = new Panel(); 
         PictureBox pb = new PictureBox(); 
         TextBox tb = new TextBox(); 
         Image loadedImage = Image.FromFile(file); 
         pb.Height = 200; 
         pb.Width = 200; 
         pb.Image = loadedImage; 
         pb.SizeMode = PictureBoxSizeMode.StretchImage; 
         tb.Text = openFileDialog1.FileName; 
         //panel.Controls.Add(pb); 
         panel.Controls.Add(tb); 
         panel.Height = 200; 
         panel.Width = 200; 
         flowLayoutPanel1.Controls.Add(panel); 

        } 
        catch (SecurityException ex) 
        { 
         // The user lacks appropriate permissions to read files, discover paths, etc. 
         MessageBox.Show("Security error. Please contact your administrator for details.\n\n" + 
          "Error message: " + ex.Message + "\n\n" + 
          "Details (send to Support):\n\n" + ex.StackTrace 
         ); 
        } 
        catch (Exception ex) 
        { 
         // Could not load the image - probably related to Windows file system permissions. 
         MessageBox.Show("Cannot display the image: " + file.Substring(file.LastIndexOf('\\')) 
          + ". You may not have permission to read the file, or " + 
          "it may be corrupt.\n\nReported error: " + ex.Message); 
        }

      }

private void button2_Click(object sender, EventArgs e) 
{ 

    foreach(TextBox tb in TextBoxes) 
    { 


     File.Copy(tb.Text, dest); 

    } 
} 

Answer 1

很明显，你必须保存的文件名的地方，无论是在一个文本框，像你这样（虽然我会建议代替tb.Text=file！），或者您正在使用单独的List<string>（我会推荐后者！使用表单来存储事物大多不是好主意）。

要获取文件只需迭代foreach(Control c in flowLayoutPanel1.Items)然后沿着SubControls到您的文本框或使用单独的列表。

您可以使用File.Copy(src, dest)的副本。
