SecurityPermission SecurityPermission SecurityPermission SecurityPermission Class

定義

描述套用至程式碼的安全性權限集。Describes a set of security permissions applied to code. 這個類別無法被繼承。This class cannot be inherited.

[System.Runtime.InteropServices.ComVisible(true)]
[System.Serializable]
public sealed class SecurityPermission : System.Security.CodeAccessPermission, System.Security.Permissions.IUnrestrictedPermission

備註

此權限會使用SecurityPermissionFlag列舉型別。This permission uses the SecurityPermissionFlag enumeration. 這個列舉型別的值可以找到其文件中。The values for this enumeration can be found in its documentation.

建構函式

SecurityPermission(PermissionState) SecurityPermission(PermissionState) SecurityPermission(PermissionState) SecurityPermission(PermissionState)

使用指定的受限制或不受限制使用權限,來初始化 SecurityPermission 類別的新執行個體。Initializes a new instance of the SecurityPermission class with either restricted or unrestricted permission as specified.

SecurityPermission(SecurityPermissionFlag) SecurityPermission(SecurityPermissionFlag) SecurityPermission(SecurityPermissionFlag) SecurityPermission(SecurityPermissionFlag)

使用旗標的指定初始設定狀態來初始化 SecurityPermission 類別的新執行個體。Initializes a new instance of the SecurityPermission class with the specified initial set state of the flags.

屬性

Flags Flags Flags Flags

取得或設定安全性權限旗標。Gets or sets the security permission flags.

方法

Assert() Assert() Assert() Assert()

宣告即使堆疊中較高層的呼叫端未獲得資源存取權限,呼叫程式碼仍可透過呼叫這個方法的程式碼要求權限,來存取受保護的資源。Declares that the calling code can access the resource protected by a permission demand through the code that calls this method, even if callers higher in the stack have not been granted permission to access the resource. 使用 Assert() 可能會造成安全性問題。Using Assert() can create security issues.

(Inherited from CodeAccessPermission)
Copy() Copy() Copy() Copy()

建立並傳回目前權限的相同複本。Creates and returns an identical copy of the current permission.

Demand() Demand() Demand() Demand()

如果呼叫堆疊中所有較高層的呼叫端尚未授與目前執行個體 (Instance) 所指定的使用權限,請於執行階段強制執行 SecurityExceptionForces a SecurityException at run time if all callers higher in the call stack have not been granted the permission specified by the current instance.

(Inherited from CodeAccessPermission)
Deny() Deny() Deny() Deny()

防止呼叫堆疊中較高層的呼叫端,使用呼叫這個方法的程式碼來存取目前執行個體所指定的資源。Prevents callers higher in the call stack from using the code that calls this method to access the resource specified by the current instance.

(Inherited from CodeAccessPermission)
Equals(Object) Equals(Object) Equals(Object) Equals(Object)

判斷指定的 CodeAccessPermission 物件是否等於目前的 CodeAccessPermissionDetermines whether the specified CodeAccessPermission object is equal to the current CodeAccessPermission.

(Inherited from CodeAccessPermission)
FromXml(SecurityElement) FromXml(SecurityElement) FromXml(SecurityElement) FromXml(SecurityElement)

使用 XML 編碼方式重建具有指定狀態的使用權限。Reconstructs a permission with a specified state from an XML encoding.

GetHashCode() GetHashCode() GetHashCode() GetHashCode()

取得 CodeAccessPermission 物件的雜湊碼,其適合用於雜湊表這類的雜湊演算法和資料結構。Gets a hash code for the CodeAccessPermission object that is suitable for use in hashing algorithms and data structures such as a hash table.

(Inherited from CodeAccessPermission)
GetType() GetType() GetType() GetType()

取得目前執行個體的 TypeGets the Type of the current instance.

(Inherited from Object)
Intersect(IPermission) Intersect(IPermission) Intersect(IPermission) Intersect(IPermission)

建立並傳回目前使用權限和指定之使用權限交集的使用權限。Creates and returns a permission that is the intersection of the current permission and the specified permission.

IsSubsetOf(IPermission) IsSubsetOf(IPermission) IsSubsetOf(IPermission) IsSubsetOf(IPermission)

判斷目前使用權限是否為指定之使用權限的子集。Determines whether the current permission is a subset of the specified permission.

IsUnrestricted() IsUnrestricted() IsUnrestricted() IsUnrestricted()

傳回數值,表示目前使用權限是否不受限制。Returns a value indicating whether the current permission is unrestricted.

MemberwiseClone() MemberwiseClone() MemberwiseClone() MemberwiseClone()

建立目前 Object 的淺層複本 (Shallow Copy)。Creates a shallow copy of the current Object.

(Inherited from Object)
PermitOnly() PermitOnly() PermitOnly() PermitOnly()

防止呼叫堆疊中較高層的呼叫端,使用呼叫這個方法的程式碼來存取除了目前執行個體所指定資源之外的所有資源。Prevents callers higher in the call stack from using the code that calls this method to access all resources except for the resource specified by the current instance.

(Inherited from CodeAccessPermission)
ToString() ToString() ToString() ToString()

建立並傳回目前使用權限物件的字串表示。Creates and returns a string representation of the current permission object.

(Inherited from CodeAccessPermission)
ToXml() ToXml() ToXml() ToXml()

建立使用權限的 XML 編碼方式,和其目前狀態。Creates an XML encoding of the permission and its current state.

Union(IPermission) Union(IPermission) Union(IPermission) Union(IPermission)

建立目前權限與指定權限聯集的權限。Creates a permission that is the union of the current permission and the specified permission.
