如何調整多個圖像的大小

Question

我的任務是調整多個圖像的大小。我試過這個代碼：

using System; 
using System.Collections.Generic; 
using System.ComponentModel; 
using System.Data; 
using System.Drawing; 
using System.Linq; 
using System.Text; 
using System.Threading.Tasks; 
using System.Windows.Forms; 
using System.IO; 

namespace Boyutlandir 
{ 
    public partial class Form1 : Form 
    { 
     public Form1() 
     { 
      InitializeComponent(); 
     } 
     string dosyaYolu = string.Empty; 
     Bitmap bmp = null; 
     OpenFileDialog openFileDialogDosyaAc = new OpenFileDialog(); 

     private void button1_Click(object sender, EventArgs e) 
     { 

      openFileDialogDosyaAc.Multiselect = true; 
      if (openFileDialogDosyaAc.ShowDialog() == DialogResult.OK) 
      { 
       dosyaYolu = openFileDialogDosyaAc.FileName; 

       bmp = new Bitmap(openFileDialogDosyaAc.FileNames.ToString()); 

       pictureBox1.Image = bmp; 

       pictureBox1.SizeMode = PictureBoxSizeMode.StretchImage; 
      } 

     } 

     private void button2_Click(object sender, EventArgs e) 
     { 
      Bitmap bmpKucuk = new Bitmap(pictureBox1.Image,Convert.ToInt32(textBox1.Text),Convert.ToInt32(textBox2.Text)); 
      pictureBox1.Image = bmpKucuk; 
      pictureBox1.SizeMode = PictureBoxSizeMode.CenterImage; 

     } 

     private void button3_Click(object sender, EventArgs e) 
     { 
      SaveFileDialog sfd = new SaveFileDialog(); 
      sfd.Filter = "jpeg dosyası(*.jpg)|*.jpg|Bitmap(*.bmp)|*.bmp"; 
      DialogResult sonuc = sfd.ShowDialog(); 
      if (sonuc == DialogResult.OK) 
      { 
       pictureBox1.Image.Save(sfd.FileName); 

      } 
     } 
    } 
}

好的，所以你使用winforms，並希望打開多個文件？或一個目錄？並想調整它們。但沒有調整大小？還是需要更多的咖啡？使用http://nuget.org/packages/ImageResizer/，我沒有看到一個循環來遍歷你想調整大小的文件。

在Button1的Click事件

，做這樣的事情：

private void button1_Click(object sender, EventArgs e) 
{ 
    DialogResult dr = this.openFileDialogDosyaAc.ShowDialog(); 
    if (dr == System.Windows.Forms.DialogResult.OK) 
    { 
     // Read the files 
     foreach (String file in openFileDialogDosyaAc.FileNames) 
     { 
      //resize and save 
     } 
    } 
}
