原答案

You have to draw all image to one image for displaying them in single picturebox

您必须将所有图像绘制到一个图像中才能在单个图片框中显示它们

That is bit complex you can use mutiple pictureboxes

这有点复杂，您可以使用多个图片框

In following code they are created dynamically according to need:

在以下代码中，它们是根据需要动态创建的：

    // For confirm visibility of all images set 
    this.AutoScroll = true;

    string[] list = Directory.GetFiles(@"C:\pictures", "*.jpg");
    PictureBox[] picturebox= new PictureBox[list.Length];
    int y = 0;
    for (int index = 0; index < picturebox.Length; index++)
    {
        this.Controls.Add(picturebox[index]);
        // Following three lines set the images(picture boxes) locations
        if(index % 3 == 0)
            y = y + 150; // 3 images per rows, first image will be at (20,150)
        picturebox[index].Location=new Point(index * 120 + 20, y);

        picturebox[index ].Size = new Size(100,120);
        picturebox[index].Image = Image.FromFile(list[index]);
    }

Use picturebox[index].Image = Image.FromFile(list[index]);

用 picturebox[index].Image = Image.FromFile(list[index]);
