推荐答案

图像将存储在数据库中，您可以将数据库与gridview绑定
要上传图片，请使用FileUpload Control

The image will be store in database and you can bind the database with gridview
to upload an image take FileUpload Control

protected void btnUpload_Click(object sender, EventArgs e)
    {
        try
        {


            string filename = FileUpload1.FileName;
            string fileExt = System.IO.Path.GetExtension(FileUpload1.FileName);
            if (fileExt == ".jpg" || fileExt == ".gif" || fileExt == ".bmp" || fileExt == ".JPG" || fileExt == ".GIF" || fileExt == ".png" || fileExt == ".jpeg")
            {
                FileUpload1.PostedFile.SaveAs(Server.MapPath("~\\ThoughtForDay\\" + filename));
                string path = "~\\ThoughtForDay\\" + filename;
                SqlCommand cmd = new SqlCommand("Insert into ThoughtFortheDay(Imageurl,date1,date2) values('" + path + "',@date1,@date2)", cnn);
                cmd.Parameters.AddWithValue("Imageurl",fileExt);
                cmd.Parameters.AddWithValue("date1", txtdate1.Text);
                cmd.Parameters.AddWithValue("date2", txtdate2.Text);
                cmd.CommandType = CommandType.Text;
                cnn.Open();
                cmd.ExecuteNonQuery();
                lblinfo.Text = "Uploaded Successfully";
                cnn.Close();
                
            }
            else
            {
                lblinfo.Text = "Browse Only jpg,gif,bmp,png,jpeg Image File!";
            }
        }
        catch (Exception ex)
        {
            Response.Write(ex.ToString());
        }
    
    }

ThoughtForDay是图像的名称.
在gridview中显示图像，请参见
在GridView中显示图像
在GridView中播放图像
