效果：
思路：
首先，获取图片物理地址，然后进行判断将图片保存到文件夹下，再将图片的信息保存到数据库。
数据库：
代码：
namespace InExcelOutExcel
{
public partial class UpWord : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
string SQLString = ConfigurationManager.ConnectionStrings["ConnectionStr"].ToString();
protected void UploadButton_Click(object sender, EventArgs e)
{
try
{
using (SqlConnection sqlcon = new SqlConnection(SQLString))
{
string FullName = FileUpload1.PostedFile.FileName;//获取图片物理地址
FileInfo fi = new FileInfo(FullName);
string name = fi.Name;//获取图片名称
string type = fi.Extension;//获取图片类型
if (type == ".jpg" || type == ".gif" || type == ".bmp" || type == ".png")
{
string SavePath = Server.MapPath("~\\excel");//图片保存到文件夹下
this.FileUpload1.PostedFile.SaveAs(SavePath + "\\" + name);//保存路径
this.Image1.Visible = true;
this.Image1.ImageUrl = "~\\excel" + "\\" + name;//界面显示图片
string sql = "insert into image1(ImageName,ImageType,ImagePath) values('" + name + "','" + type + "','~\\excel" + name + "')";
SqlCommand cmd = new SqlCommand(sql, sqlcon);
sqlcon.Open();
cmd.ExecuteNonQuery();
