给个例子。我以前做的。你参考一下
protected void btnsubmit_Click(object sender, EventArgs e)
        {
            if (upImages.HasFile)
            {
                if (CheckImageType(upImages.FileName))
                {
                    string ImagePath = "~/uploadImage/" + upImages.FileName;
                    upImages.SaveAs(MapPath(ImagePath));
                    SqlConnection cn = new SqlConnection(ConfigurationManager.AppSettings["Conn"].ToString());
                    SqlCommand cmd = new SqlCommand("insert into PPhoto(photoImage) values(@photoImage)", cn);
                    cmd.Parameters.AddWithValue("@photoImage", "~/uploadImage/" + upImages.FileName);
                    cn.Open();
                    cmd.ExecuteNonQuery();
                    cn.Close();
                    Page.ClientScript.RegisterStartupScript(this.GetType(), "", "<script>alert('上传成功');</script>");
                }
                else
                {
                    Page.ClientScript.RegisterStartupScript(this.GetType(), "", "<script>alert('上传失败');</script>");
                }
            }
        }        private bool CheckImageType(string ImageName)
        {
            string ext = Path.GetExtension(ImageName);
            switch (ext.ToLower())
            {
                case ".gif": return true;
                case ".png": return true;
                case ".jpg": return true;
                case ".jpeg": return true;
                default: return false;
            }
        }
