我試圖實現我的自定義安全屬性。這是現在自定義安全屬性中的無效mscorlib異常c'tor
[Serializable]
[ComVisible(true)]
[AttributeUsage(AttributeTargets.Class | AttributeTargets.Method, AllowMultiple = true, Inherited = false)]
public class SecPermissionAttribute : CodeAccessSecurityAttribute
{
public SecPermissionAttribute(SecurityAction action) : base(action) { }
public override System.Security.IPermission CreatePermission()
{
IPermission perm = new PrincipalPermission(PermissionState.Unrestricted);
return perm;
}
}
出於某種原因很簡單,我得到了在屬性異常c'tor
System.IO.FileLoadException occurred
Message=The given assembly name or codebase, 'C:\WINDOWS\Microsoft.Net\assembly\GAC_32\mscorlib\v4.0_4.0.0.0__b77a5c561934e089\mscorlib.dll', was invalid.
Source=WcfRoleProviderTestService
StackTrace:

at WcfRoleProviderTestService.Service1.GetData(Int32 value) in D:\TestProjects\WcfRoleProviderTestService\WcfRoleProviderTestService\Service1.svc.cs:line 19
InnerException:
DLL被簽署。在我看來,這似乎是一個安全問題,但我不確定。順便說一下,我試圖使用PrincipalPermissionAttribute,它工作正常。 忘了說,我使用VS 2010,FW 4.0,屬性在WCF服務中保留 我很樂意得到一些幫助。
我的服務配置如下

我得到的錯誤都在Windows XP,IIS V5.1和Windows Server只有在WCF服務配置爲使用2008 R2 IISV7.5上Windows身份驗證(請參閱上面的配置)。更有趣的事實是,僅當該屬性與System.Security.Permissions.SecurityAction.Demand
安全操作一起使用時纔會發生錯誤。
[OperationBehavior(Impersonation = ImpersonationOption.Allowed)]
[SecPermission(System.Security.Permissions.SecurityAction.Demand)]
public string GetData(int value)
{
string userName = ServiceSecurityContext.Current.WindowsIdentity.Name;
return string.Format("You entered: {0}, User {1}", value, userName);
}
其他選項正常工作。 謝謝。
不幸的是,我似乎無法重現這個問題。該屬性是在您的服務項目中還是在單獨的DLL中聲明的?當你說DLL被簽名,哪個DLL被簽名以及它是什麼類型的簽名(強名稱或者真實代碼)?另外,您的代碼的哪些部分已經應用了該屬性? –
嗨@Nicole,我試過了,單獨的dll和服務的dll,結果是一樣的。現在,爲了簡單起見,該屬性在與服務相同的dll中定義,並且使用字符串名稱(* .snk文件)對dll進行簽名。該屬性應用於Service方法(實現,而不是合同)。 –
我仍然不能重現這個問題。你如何主辦這項服務?此外,您是否對默認行爲,激活等進行了任何更改? –
