如何在.net Framework 4下捕獲未找到的資源程序集異常？

Question

我最近將DotNetNuke 6安裝切換到.net 4框架，並且我開始遇到以下錯誤：

DotNetNuke.Services.Exceptions.PageLoadException: Exception has been thrown by the target of an invocation. ---> System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.IO.FileNotFoundException: Could not find file 'Telerik.Web.UI.resources'.

我不知道為什么會發生此錯誤，因為我無法在另一台服務器甚至同一台服務器上重現它。 由於找不到解決方案，因此我嘗試對其進行修補，因此我查看了本文中建議的解決方法： http : //social.msdn.microsoft.com/Forums/vstudio/en-US/32e458a1-7443- 4309-a054-8839b33dfd4f / framework-40-dll由20個可執行文件無法找到xxxxresourcesdll加載

因此，解決方法是

在HostRuntime.ResolveAssembly中捕獲FileNotFoundException並返回null。 這樣可以防止進程崩潰。

我可以通過HttpModule向應用程序中添加一些代碼，但是我真的看不到如何修補HostRuntime.ResolveAssembly ...知道嗎？

編輯：我一直在框架4的mscorlib程序集中挖掘，我看到一些很奇怪的東西：

從ManifestBasedResourceGroveler到SatelliteAssembly加載的調用如下：

try
    {
        runtimeAssembly = this._mediator.MainAssembly.InternalGetSatelliteAssembly(satelliteAssemblyName, lookForCulture, this._mediator.SatelliteContractVersion, false, ref stackMark);
    }
    catch (FileLoadException ex)
    {
        int hResult = ex._HResult;
        Win32Native.MakeHRFromErrorCode(5);
    }
    catch (BadImageFormatException)
    {
    }

因此它捕獲了異常，但這是InternalGetSatelliteAssembly的代碼

if (runtimeAssembly == this)
    {
        throw new FileNotFoundException(string.Format(culture, Environment.GetResourceString("IO.FileNotFound_FileName"), new object[]
        {
            assemblyName.Name
        }));
    }

好的，所以我總是會得到一個不會被捕獲的FileNotFoundException……對我來說這看起來像是一個很奇怪的行為

根據堆棧跟蹤，它看起來像是Telerik版本問題。 您確定所有正確的程序集都已加載嗎？
