            openFileDialog.Filter = "Text Files (*.jpg)|*.txt|All Files (*.*)|*.*";
            if (openFileDialog.ShowDialog(this) == DialogResult.OK)

                string FileName = openFileDialog.FileName;
                pictureBox1.ImageLocation = FileName;
            }

private void button1_Click(object sender, EventArgs e)
        {
            OpenFileDialog openFileDialog = new OpenFileDialog();
            if (openFileDialog.ShowDialog() == DialogResult.OK)
            {
                this.pictureBox1.Image = Image.FromFile(openFileDialog .FileName );

            this.pictureBox1.ImageLocation=openFileDialog .FileName ;
            
        }

Answer 4

是不是异步编程？
  private void btnLoadpicture_Click（object sender，EventArgs s）
{
      pictureBox1.LoadAsync("路径")； //路径中/要用//代替。这点不解释撒
}
private void btnLoadpicture_Click（object sender，EventArgs s）
{
       pictureBox1.CancelAsync();//取消
}

Answer 5

private void button1_Click(object sender, EventArgs e)
  {
  OpenFileDialog openFileDialog = new OpenFileDialog();
  if (openFileDialog.ShowDialog() == DialogResult.OK)
  {
  this.pictureBox1.Image = Image.FromFile(openFileDialog .FileName );
  }
  this.pictureBox1.ImageLocation=openFileDialog .FileName ;
    
  }
这样就行
