備註

由此建構子所建立的動態方法，與匿名組件相關聯，而非現有的型別或模組。 匿名組合語言僅存在於為動態方法提供沙盒環境，也就是將它們與其他程式碼隔離。 此環境使得部分信任的程式碼能安全地發出並執行動態方法。

此建構器規定，動態方法的 Microsoft 中介語言（MSIL）將強制執行即時（JIT）可視性檢查。 也就是說，動態方法中的程式碼可以存取公開類別的公開方法。 若方法嘗試存取類型或成員為 private、protected 或 internal（在 Visual Basic 中為 Friend），則會拋出例外。 若要建立一個動態方法，且能限制跳過 JIT 可見性檢查，請使用建構子。DynamicMethod(String, Type, Type[], Boolean)

當建立匿名託管的動態方法時，會包含該發射組件的呼叫堆疊。 當方法被呼叫時，會使用發射組件的權限，而非實際呼叫者的權限。 因此，動態方法無法執行高於發出它的組合語言的權限，即使它被傳遞並執行給擁有較高信任等級的組裝。

此建構子指定方法屬性 MethodAttributes.Public 與 MethodAttributes.Static，以及呼叫慣例 CallingConventions.Standard。

由此建構子所建立的動態方法，與匿名組件相關聯，而非現有的型別或模組。 匿名組合語言僅存在於為動態方法提供沙盒環境，也就是將它們與其他程式碼隔離。 此環境使得部分信任的程式碼能安全地發出並執行動態方法。

匿名託管的動態方法無法自動存取任何類型或成員，這些類型private、protected 或 internal（Visual Basic 中稱為Friend）。 這與與現有型別或模組相關的動態方法不同，後者可存取其相關範圍內的隱藏成員。

請指定 true 給 restrictedSkipVisibility，如果你的動態方法必須存取 private、protected 或 internal 的類型或成員。 這使動態方法對這些成員的存取受限制。 也就是說，只有在符合以下條件時，才能存取這些成員：

• 目標成員屬於一個擁有等於或低於發出動態方法的呼叫堆疊的信任等級的集合體。

• 發出動態方法的呼叫堆疊會被賦予標記 ReflectionPermission 和旗標 ReflectionPermissionFlag.RestrictedMemberAccess。 當程式碼以完全信任執行時，這點總是成立的。 對於部分可信的程式碼，只有當主機明確授予權限時才成立。

  Important

  若未授予權限，則在呼叫或動態方法被呼叫時拋出 CreateDelegate 安全異常，而非此建構子被呼叫時。 發射動態方法不需要特殊權限。

例如，一個動態restrictedSkipVisibilitytrue方法設定為 ，若呼叫堆疊已獲得限制成員存取權，則可存取呼叫堆疊中任一組裝的私人成員。 若動態方法在呼叫堆疊中使用部分受信任的程式碼，則無法存取 .NET Framework 組合語言中某類型的私有成員，因為此類組合是完全受信任的。

若 restrictedSkipVisibility 為 false，則會強制執行 JIT 可視性檢查。 動態方法中的程式碼可存取公開類別的公開方法，若嘗試存取屬於 private、 protected、 或 internal的類型或成員，則會拋出例外。

當建立匿名託管的動態方法時，會包含該發射組件的呼叫堆疊。 當方法被呼叫時，會使用發射呼叫堆疊的權限，而非實際呼叫者的權限。 因此，動態方法無法執行高於發出它的組合語言的權限，即使它被傳遞並執行給擁有較高信任等級的組裝。

範例

以下程式碼範例會產生 DynamicMethod 一個邏輯上與某個型別相關聯的 。 這個協會讓它能接觸到該類型的私人會員。

程式碼範例定義了一個帶有私有欄位的類別Example，一個從第一個類別衍生出來的類別DerivedFromExample，一個名為UseLikeStatic的代理型別（返回Int32，且參數類型為Example和Int32），以及一個名為UseLikeInstance的代理型別，返回Int32且有一個參數類型為Int32。

範例程式碼接著建立DynamicMethod，改變Example實例的私有欄位並回傳先前的值。

範例程式碼先建立一個 的 Example 實例，然後再建立兩個代理。 第一個是型別 UseLikeStatic，其參數與動態方法的相同。 第二種是型別 UseLikeInstance，但缺少第一個參數（型別 Example）。 這個代理是透過 CreateDelegate(Type, Object) 方法超載建立的;該方法超載的第二個參數是 的 Example一個實例，在此例中是剛建立的實例，該實例綁定於新建立的代理。 每當該代理被調用時，動態方法就會作用於綁定的 實例 Example。

UseLikeStatic代理人被召喚，若 與代理人有約束UseLikeInstance，則由代理人召喚Example。 接著會召喚代理 UseLikeInstance ，使得兩個代理都在 的 Example同一實例上行動。 每次呼叫後會顯示內部欄位值的變化。 最後，將UseLikeInstance代理繫結到DerivedFromExample實例上，然後重複呼叫該代理。

備註

使用此建構子所建立的動態方法可存取 owner 型別的所有成員，以及包含 internal 的模組中所有其他型別的公用和 Friend 成員（在 Visual Basic 中為 owner）。

此建構子指定方法屬性 MethodAttributes.Public 與 MethodAttributes.Static，呼叫慣例 CallingConventions.Standard，且不會跳過即時（JIT）可見性檢查。
