在我的 ASP.NET 应用程序中,有 MyAssembly.CustomIdentity
类和 .NET 运行时 tries to serialize that class 。在序列化期间,它会抛出 FileNotFoundException
提示它无法加载 MyAssembly
。

我搜索了一下,看起来处理 AppDomain.AssemblyResolve
事件应该有所帮助。所以我实现了对该事件的处理:
public partial class Default : System.Web.UI.Page
{
static Assembly MyResolveEventHandler(object sender, ResolveEventArgs args)
{
return typeof(MyAssembly.CustomIdentity).Assembly;
}
protected void Page_Load(object sender, EventArgs e)
{
AppDomain currentDomain = AppDomain.CurrentDomain;
currentDomain.AssemblyResolve +=
new ResolveEventHandler(MyResolveEventHandler);
// this code throws `FileNotFoundException`
// during a serialization attempt
bool isAvailable =
Microsoft.WindowsAzure.ServiceRuntime.RoleEnvironment.IsAvailable;
}
}
但是我的处理程序没有被调用,并且在序列化尝试期间我仍然遇到相同的异常。如何解决此问题 - 如何让序列化程序找到我的程序集?
最佳答案
该问题可能与以下事实有关:CLR 在开始调用方法时尝试查找所有程序集,以便在为 AssemblyResolve 事件连接事件处理程序之前查找程序集。要解决此问题,您可以将需要程序集的代码提取到单独的方法中,然后从 Page_Load 调用它。
