img.Attributes["width"] = "95";

根据个人的情况对后台稍加改动其实net即可.

else

img.Attributes["height"] = "95";

if (height >= width)

int width = objPic.Width;

int height = objPic.Height;

System.Drawing.Bitmap objPic = new System.Drawing.Bitmap(fileName);

string fileName = Request.PhysicalApplicationPath + img.Src.Remove(0,2).Replace("/", @"\");

HtmlImage img = (HtmlImage)item.FindControl("imgPic");

foreach (DataListItem item in dataList1.Items)

2.cs听说后台文件

<img src='<%#"~/"+DataBinder.Eval(Container.DataItem,"Image").ToString()%>' border="0" id="imgPic" runat="server" />

1.aspx其实asp文件
