小编sha*_*eeq的帖子

我想在c#中创建一个项目,如果它的大小<150 kb,我想将图像上传到数据库.如何设置上传图片的限制？我不知道如何扩展它？请提前帮助谢谢

private void Browsebutton3_Click(object sender, EventArgs e)
{
        OpenFileDialog ofd = new OpenFileDialog();
        ofd.Filter = "images only.|*.jpg; *.jpeg; *.png";
        DialogResult dr = ofd.ShowDialog();
        pictureBox1.Image = Image.FromFile(ofd.FileName);
        //pictureBox1.SizeMode = PictureBoxSizeMode.CenterImage;

        textBox5.Text = ofd.FileName;
}
