FileLoad文件上传

背景：VisualStuio2005；

              实现图片上传及显示图片功能；

              服务器端文件上传目录：upload

 

实现：

public partial class upload : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
    
    }
    protected void btnUpload_Click(object sender, EventArgs e)
    {
        try
        {
          
            string fullFileName = this.FileUpload1.PostedFile.FileName;
            string FileName = fullFileName.Substring(fullFileName.LastIndexOf("\\") + 1);
            string FileType = FileName.Substring(FileName.LastIndexOf(".") + 1);
            if (FileType == "jpg" || FileType == "gif" || FileType == "bmp" || FileType == "jpeg")
            {
                this.Image1.ImageUrl = fullFileName;
                this.FileUpload1.PostedFile.SaveAs(Server.MapPath("upload" + "\\" + FileName));
                this.Image1.ImageUrl = "upload/" + FileName;
                Response.Write("图片上传成功！"+"<br>");
                Response.Write("源文件为:" + fullFileName);
               
            }
            else
            {
                //Response.Write("图片格式不符，请重新上传！");
                Response.Write("<script language='javascript'>alert('图片格式不符，请重新上传！');</script>");
            }
        }
        catch (Exception ex)
        {
            Response.Write("上传失败！");
        }
       
   }
 
}

 

注意：上传文件目录upload必须设置可写权限，否则会插入失败
