Answer 1

这样做可以完美地显示完整的图像。

 private void button1_Click_1(object sender, EventArgs e)
    {
        OpenFileDialog open = new OpenFileDialog();
        if (open.ShowDialog() == DialogResult.OK)
        {

            pictureBox1.ImageLocation = open.FileName;
            pictureBox1.SizeMode = PictureBoxSizeMode.Zoom;

        }
    }

Answer 2

有＆＃34; Open＆＃34;和＆＃34;取消＆＃34; OpenfileDialog上的按钮。因为没有＆＃34; OK＆＃34;按钮，＆＃34;如果条件＆＃34;不会是真的。你应该把它改成：

Private void button1_Click(object sender, EventArgs e)
    {
        OpenFileDialog open = new OpenFileDialog();
        if (open.ShowDialog() != DialogResult.Cancel)
        {

            pictureBox1.ImageLocation = open.FileName;   

        }
    }
