代码如下:private void button2_Click_1(object sender, System.EventArgs e)
{
string pathName;
if (this.openFileDialog1.ShowDialog()==System.Windows.Forms.DialogResult.OK)
{
pathName = this.openFileDialog1.FileName;
System.Drawing.Image img = System.Drawing.Image.FromFile(pathName);
this.pictureBox1.Image
