未調用AssemblyResolve，並在序列化期間拋出FileNotFoundException

在我的ASP.NET應用程序中有MyAssembly.CustomIdentity類和.NET運行時tries to serialize that class。在序列化期間，它會引發FileNotFoundException抱怨它無法加載MyAssembly。未調用AssemblyResolve，並在序列化期間拋出FileNotFoundException

[SerializationException: Unable to find assembly 'MyAssembly, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'.]

    SampleWebApp.Default.Page_Load(Object sender, EventArgs e) in C:\Temp\AzureAdvancedRolesSource\Ex2-StartupTasks\CS\Begin\SampleWebApp\Default.aspx.cs:22

我搜索，看起來像處理AppDomain.AssemblyResolve事件應該幫助。所以，我實現了處理該事件：

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; 
    } 
}

但是我的處理程序不被調用，我仍然有一個序列化嘗試期間相同的異常。我如何解決這個問題 - 我如何讓序列化程序找到我的程序集？

什麼是異常消息？ – SLaks

對於初學者，你不應該盲目地**返回你的程序集;你需要檢查'args'來查看它要求的內容......但是：現在有什麼異常消息？ –

@SLaks，@Marc Gravell ::我添加了調用堆棧，我想它提供了最詳細的信息。 – sharptooth

該問題可能與CLR在開始調用方法時嘗試查找所有程序集，以便在爲AssemblyResolve事件連接事件處理程序之前查找程序集有關。爲了解決這個問題，你可以把需要你的程序集的代碼提取到一個單獨的方法中，並從Page_Load中調用它。
