備註

MemberAccessExceptionFieldAccessExceptionMethodAccessExceptionMissingMemberExceptionMissingMethodExceptionMissingFieldException的基類,以及(僅限.NET Native.NET Native)。MemberAccessException is the base class for FieldAccessException, MethodAccessException, MissingMemberException, MissingMethodException, and MissingFieldException, and (.NET Native.NET Native only). 當找不到類別成員或不允許存取成員時,就會擲回這些例外狀況。These exceptions are thrown when a class member is not found or access to the member is not permitted.

下列方法會擲回 MemberAccessExceptionMemberAccessException is thrown by the following methods:

System.Reflection 類別的 InvokeFieldInfo 類別的 GetValue,以及 DynamicInvoke 類別的 DelegateInvoke of the System.Reflection classes, GetValue of the FieldInfo class, and DynamicInvoke of the Delegate class.

使用 .NET Native.NET Native 工具鏈編譯的應用程式可能會在執行時間擲回例外狀況。Apps compiled by using the .NET Native.NET Native tool chain may throw a exception at runtime. 是衍生自 MemberAccessException的內部唯一例外狀況類型。is an internal-only exception type derived from MemberAccessException. 例外狀況表示執行應用程式成功所需的中繼資料不存在於執行時間。The exception indicates that metadata needed for the successful execution of an app is not present at runtime. 您不應該使用 try/catch 區塊來處理例外狀況。You should not use a try/catch block to handle the exception. 相反地,您應該判斷缺少哪些中繼資料,並修改您的應用程式,以確保它存在於執行時間。Instead, you should determine what metadata is missing and modify your app's to ensure that it is present at runtime.

MemberAccessException 使用具有值0x8013151A 的 HRESULT COR_E_MEMBERACCESS。MemberAccessException uses the HRESULT COR_E_MEMBERACCESS, that has the value 0x8013151A.
