怎么将pictureBox中的图片保存到硬盘上
谢谢

------解决方案--------------------
类似如下的代码:
this.pictureBox1.Image.Save(@ "D:\tu.bmp ")
------解决方案--------------------
写的明子的话,就是如下的样子:
private void button1_Click(object sender, EventArgs e)
{
if (this.pictureBox1.Image != null)
{
SaveFileDialog sd = new SaveFileDialog();
if (sd.ShowDialog(this) == DialogResult.OK)
{
this.pictureBox1.Image.Save(sd.FileName);
}
}
}
