%> 参考技术B 上传文件类型及大小自定，自定上传文件夹，如果文件夹不存在则自动建立，如果文件名重复自动替换，上传完成显示文件路劲，这样的上传文件有现成的，但是要保存到数据库需要手动完成了，用得上的话加百度hi发给你。
ASP.NET利用.FileUpload上传图片并将图片名称保存到数据库，我要具体的代码
参考技术A 放一个fileupload控件，另外放一个button按钮，控制上传，在button的click事件中写：if(fileupload.hasfile) //判断是否存在文件
string FilePath = Server.MapPath("/UploadFile/"); //获取图像存的路径
string Extension = Path.GetExtension(fileupload.PostedFile.FileName); //获取文件的类型
if(extension != ".jpg") //判断是不是jpg格式，需要其他格式多加几个或者用字符处理方式都行
return ;
string NewFilePath = DateTime.Now.ToString("yyyyMMddHHmmss") + Extension; //重命名图片，也可以用图片原有的名字
fileupload.SaveAs(FilePath + NewFilePath); //图片存到对应路径
string ImgPath = "/UploadFile/" + NewFilePath; //获取上传好的图片的路径
//将字符串存入数据库对应的字段即可
追问
写的很好，有没有可以判断图片上传不能超过多少MB的？
追答在webconfig里面可以设置全局的大小，字节的话，你用限制的大小换算一下
不加这个得话，默认是4M
另外也可以再代码里面判断
HttpPostedFile upFile = fileupload.PostedFile;
int fileLength = upFile.ContentLength;
但是大小不能超过在webconfig里面设置的
原来是大神，遇到不懂的还可以问你么？
追答算不上大神，一起学习，有不懂的可以一起探讨探讨
