我有以下代码,我希望简单地在使用 IIS 7 运行它的浏览器中加载该页面。
<%@ Page Language="C#" Debug="true" %>
<%
using System;
protected string callRotate()
{
ProcessStartInfo info = new ProcessStartInfo();
string[] arguments = { "arg1" , "arg2" };
info.FileName = "ConsoleApplication1";
Process process = Process.Start(info.FileName, arguments);
Process.Start(info);
}
%>
这是我在浏览器中遇到的错误:
Server Error in '/' Application.

更新 3: 好吧,以前我切换到使用命令行应用程序,因为我无法让任何代码在浏览器中工作,但现在你已经向我展示了如何切换回在浏览器中运行它。
所以我已经使用了我的应用程序并将其转换为在浏览器中工作,一切都很好。但是我该如何获取 url 变量呢?
我知道这与 Request.QueryString 有关,但这不起作用,我添加了以下行:
当前代码:
<%@ Page Language="C#" Debug="true" %>
<%@ Import Namespace="System" %>
<%@ Import Namespace="System.Drawing" %>
<%@ Import Namespace="System.Web" %>
<script runat="server">
static void Main(string[] args)
{
string url = Request.QueryString["url"];
string rotate_dir = Request.QueryString["dir"];
//create an image object from the image in that path
System.Drawing.Image img = System.Drawing.Image.FromFile(url);
//Rotate the image in memory
if (direction == "clockwise")
{
//Rotate clockwise
img.RotateFlip(RotateFlipType.Rotate90FlipNone);
} else if (direction == "anticlockwise")
{
//Rotate anti-clockwise
img.RotateFlip(RotateFlipType.Rotate90FlipXY);
}
//Delete the file so the new image can be saved
System.IO.File.Delete(url);
//save the image to the file
img.Save(url);
//release image file
img.Dispose();
}
</script>
