MethodAccessException 類別

定義

當嘗試存取某個方法 (例如,從部分信任的程式碼中存取私用方法) 而無效時,所擲回的例外狀況。The exception that is thrown when there is an invalid attempt to access a method, such as accessing a private method from partially trusted code.

public ref class MethodAccessException : MemberAccessException
[System.Runtime.InteropServices.ComVisible(true)]
[System.Serializable]
public class MethodAccessException : MemberAccessException
type MethodAccessException = class
    inherit MemberAccessException
Public Class MethodAccessException
Inherits MemberAccessException

備註

注意

此例外狀況不包含在適用于 Windows Store 應用程式的 .net中, 或可移植的類別庫中, 但由的某些成員擲回。This exception is not included in the .NET for Windows Store apps or the Portable Class Library, but it is thrown by some members that are. 若要在這種情況下攔截例外狀況catch , 請MemberAccessException改為撰寫的語句。To catch the exception in that case, write a catch statement for MemberAccessException instead.

在下列情況中會擲回這個例外狀況:This exception is thrown in situations such as the following:

  • 無法從一般已編譯器代碼存取的私用、受保護或內部方法, 會使用反映從部分信任的程式碼存取。A private, protected, or internal method that would not be accessible from normal compiled code is accessed from partially trusted code by using reflection.

  • 安全性關鍵方法是從透明程式碼存取。A security-critical method is accessed from transparent code.

  • 類別庫中方法的存取層級已變更, 且一或多個參考程式庫的元件尚未重新編譯。The access level of a method in a class library has changed, and one or more assemblies that reference the library have not been recompiled.

注意

從開始, common language runtime 會在以部分信任執行時, 將應用程式代碼視為透明。 .NET Framework 4.NET Framework 4Beginning with the .NET Framework 4.NET Framework 4, the common language runtime treats application code as transparent when it is run with partial trust. 請參閱反映的安全性考慮See Security Considerations for Reflection.

MethodAccessException會使用具有值0x80131510 的 HRESULT COR_E_METHODACCESS。MethodAccessException uses the HRESULT COR_E_METHODACCESS, that has the value 0x80131510.

建構函式

MethodAccessException()

初始化 MethodAccessException 類別的新執行個體,設定新執行個體的 Message 屬性為描述錯誤的系統提供訊息,例如「嘗試存取方法失敗」。Initializes a new instance of the MethodAccessException class, setting the Message property of the new instance to a system-supplied message that describes the error, such as "Attempt to access the method failed." 此訊息會考量目前的系統文化特性。This message takes into account the current system culture.

MethodAccessException(SerializationInfo, StreamingContext)

使用序列化資料,初始化 MethodAccessException 類別的新執行個體。Initializes a new instance of the MethodAccessException class with serialized data.

MethodAccessException(String)

使用指定的錯誤訊息,初始化 MethodAccessException 類別的新執行個體。Initializes a new instance of the MethodAccessException class with a specified error message.

MethodAccessException(String, Exception)

使用指定的錯誤訊息以及造成此例外狀況的內部例外狀況的參考,初始化 MethodAccessException 類別的新執行個體。Initializes a new instance of the MethodAccessException class with a specified error message and a reference to the inner exception that is the cause of this exception.
