如何在ASP.NET中将图像添加到数据库？ [英] How can l add image to database in ASP.NET ?

问题描述

我想通过网站将图片添加到我的数据库中，我已经为它编写了代码，但由于某些原因它无法正常工作!!



如果单击按钮，则会出现此错误： -



_ System.Web.dll中出现System.Web.HttpException类型的异常，但是不在用户代码中处理。



_附加信息：SaveAs方法配置为需要根路径，路径'Images / Image0 2'不是root。



错误引用此代码： -

 imageFile.SaveAs（Images /& N_image）

我尝试过：

  Dim  ftype  As   String  
  Dim  N_image  As   String  
 
 ftype = System.IO.Path.GetExtension（imageFi le.FileName）
 
 ImgDS.InsertParameters（  Hall_Namber）。DefaultValue = DropDownList1.SelectedValue 
 ImgDS.InsertParameters（  Image）。DefaultValue = N_image 
 ImgDS.Insert（）
 
 N_image =  图像& DropDownList1.SelectedValue&  & GridView3.Rows.Count +  1  
 imageFile.SaveAs（  Images /& N_image）
 

解决方案

请先阅读我的评论。 ..



Google上有很多例子（使用声明： asp.net vb.net将图像插入数据库），见：

I want to add a picture to my database through the website, I've written the code for it, but it does not work for some reason!!

This error appears to me if I click on button :-

_ an exception of type "System.Web.HttpException' occurred in System.Web.dll but was not handled in user code.

_ Additional information: The SaveAs method is configured to require a rooted path, and the path'Images/Image0 2' is not rooted.

The error refers to this code:-

imageFile.SaveAs("Images/" & N_image)

What I have tried:

Dim ftype As String
Dim N_image As String

ftype = System.IO.Path.GetExtension(imageFile.FileName)

ImgDS.InsertParameters("Hall_Namber").DefaultValue = DropDownList1.SelectedValue
ImgDS.InsertParameters("Image").DefaultValue = N_image
ImgDS.Insert()

N_image = "Image" & DropDownList1.SelectedValue & " " & GridView3.Rows.Count + 1
imageFile.SaveAs("Images/" & N_image)

解决方案
