C# ApplicationHost.CreateApplicationHost:System.IO.FileNotFoundException

c# asp.net iis

C# ApplicationHost.CreateApplicationHost:System.IO.FileNotFoundException,c#,asp.net,iis,C#,Asp.net,Iis,我正在尝试使用CreateApplicationHost呈现ASP网页的内容。具体代码如下： public class LocalPageContentAppropriator { private RemoteDomain _host; protected RemoteDomain Host { get { if (_host == null) { _host = (RemoteDomain)Applicat

我正在尝试使用

CreateApplicationHost

呈现ASP网页的内容。具体代码如下：

public class LocalPageContentAppropriator {
    private RemoteDomain _host;
    protected RemoteDomain Host {
        get {
            if (_host == null) {
                _host = (RemoteDomain)ApplicationHost.CreateApplicationHost(typeof(RemoteDomain), "/", SettingsFactory.Instance.WebFileRoot + "\\");
            }
            return _host;
        }
    }

    public string Resolve(string page, string query) {
        return Host.ProcessRequest(page, query);
    }
}

public class RemoteDomain : MarshalByRefObject {
    public string ProcessRequest(string page, string query) {
        using (StringWriter sw = new StringWriter()) {
            SimpleWorkerRequest work = new SimpleWorkerRequest(page, query, sw);
            HttpRuntime.ProcessRequest(work);
            return sw.ToString();
        }
    }
}

SettingsFactory.Instance.WebFileRoot

返回的路径指向网站的物理目录。尝试添加“\bin\”等，但无论我尝试了什么，我仍然会收到相同的错误，即使我故意输入了错误的路径

现在，这里是它变得有趣的地方。当正确加载程序集时（在正常使用下），Fusion日志记录通常会返回如下内容：

但是，错误显示了不同（不正确）的Appbase路径：

各位，有什么想法吗？

我现在不知道你们是否得到了答案，但我正在尝试同样的事情，遇到了同样的问题

一个也是最简单的方法是将程序集放在GAC中

第二，还有一点棘手的是，将程序集复制到“physicalDir”目录中的“bin”目录，该目录用作ApplicationHost.CreateApplicationHost方法的参数

这里有很好的解释：

ApplicationHost.CreateApplicationHost的实现需要在以下两个位置之一找到指定类型的程序集：全局程序集缓存（GAC）中或指定物理目录下的bin目录中。除了重新实现CreateApplicationHost之外，没有记录在案的方法来更改此行为。因此，根据您的项目配置和部署场景，您可能需要将程序集安装到这些位置之一

请查看更多详细信息

理想情况下，您的主机将位于不同的程序集中（您部署在物理服务器目录的“bin”下）
