PictureBox1的图片问题
1.PictureBox1里的图片怎么清空啊
2.有3个控件，一个PictureBox1，一个Textbox1,一个button1
在PictureBox1里插入图片后，在Textbox1里写入要保存这个图片的文件名，然后 一按button1，就直接是以Textbox1的TEXT为文件名后面加个“.jpg”直接保存到bin下，请问怎么实现啊

1.PictureBox1.Image = Nothing
2.PictureBox1.Image.Save(TextBox1.Text & ".jpg ", System.Drawing.Imaging.ImageFormat.Jpeg)

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
PictureBox1.Image.Save(TextBox1.Text & ".jpg ", System.Drawing.Imaging.ImageFormat.Jpeg)
End Sub

[解决办法]

问题2.Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
PictureBox1.Image.Save(TextBox1.Text & ".jpg ", System.Drawing.Imaging.ImageFormat.Jpeg)

TextBox1输入C:\123就可以保存在c盘根目录下了。
