AllowPartiallyTrustedCallersAttribute 클래스

정의

부분적으로 신뢰할 수 있는 코드에서 어셈블리를 호출할 수 있도록 허용합니다.Allows an assembly to be called by partially trusted code. 이 선언이 없으면 완전히 신뢰할 수 있는 호출자만 해당 어셈블리를 사용할 수 있습니다.Without this declaration, only fully trusted callers are able to use the assembly. 이 클래스는 상속될 수 없습니다.This class cannot be inherited.

예제

다음 예제에서는 AllowPartiallyTrustedCallersAttribute 클래스를 사용하는 방법을 보여 줍니다.The following example shows how to use the AllowPartiallyTrustedCallersAttribute class.

// The following HTML code can be used to call the user control in this sample.
//
//  <OBJECT id="usercontrol" classid="usercontrol.dll#UserControl.UserControl1" width="800"
//  height="300" style="font-size:12;">
// To run this test control you must create a strong name key, snkey.snk, and
// a code group that gives full trust to assemblies signed with snkey.snk.
// The user control displays an OpenFileDialog box, then displays a text box containing the name of
// the file selected and a list box that displays the contents of the file.  The selected file must
// contain text in order for the control to display the data properly.
// Caution  This sample demonstrates the use of the Assert method.  Calling Assert removes the
// requirement that all code in the call chain must be granted permission to access the specified
// resource, it can open up security vulnerabilities if used incorrectly or inappropriately. Therefore,
// it should be used with great caution.  Assert should always be followed with a RevertAssert
// command to restore the security settings.

부분적으로 신뢰할 수 있는 코드는 더 이상 지원 되지 않습니다.Partially trusted code is no longer supported. 이 특성은 .NET Core에는 영향을 주지 않습니다.This attribute has no effect in .NET Core.

참고

.NET Framework 4.NET Framework 4에는 AllowPartiallyTrustedCallersAttribute 특성의 동작에 영향을 주는 새로운 보안 규칙이 도입 되었습니다 ( 보안 투명 코드, 수준 2참조).The .NET Framework 4.NET Framework 4 introduces new security rules that affect the behavior of the AllowPartiallyTrustedCallersAttribute attribute (see Security-Transparent Code, Level 2). .NET Framework 4.NET Framework 4모든 코드의 기본값은 보안 투명, 즉 부분적으로 신뢰할 수 있는 코드입니다.In the .NET Framework 4.NET Framework 4, all code defaults to security-transparent, that is, partially trusted. 그러나 개별 형식 및 기타 투명도 특성을 할당 하는 멤버 주석을 달 수 있습니다.However, you can annotate individual types and members to assign them other transparency attributes. 이러한 보안과 기타 보안 변경 내용은 보안 변경 내용을 참조 하세요.For this and other security changes, see Security Changes.

AllowPartiallyTrustedCallersAttribute (APTCA) 특성을 효과적으로 사용 하려면 .NET Framework 버전 2.0 () 어셈블리를 강력한 이름으로 지정 해야 합니다..NET Framework version 2.0 () assemblies must be strong-named to effectively use the AllowPartiallyTrustedCallersAttribute (APTCA) attribute. .NET Framework 4.NET Framework 4 () 어셈블리는 어셈블리를 강력 하 게 명명 하지 않아도 APTCA 특성이 적용 될 수 있으며, 투명 하 고 보안에 중요 하며 보안 안전에 중요 한 코드를 포함할 수 있습니다.() assemblies do not have to be strong-named for the APTCA attribute to be effective, and they can contain transparent, security-critical and security-safe-critical code. 어셈블리 수준에서 특성을 적용 하는 방법에 대 한 자세한 내용은 특성 적용을 참조 하세요.For more information about applying attributes at the assembly level, see Applying Attributes.

기본적으로는 강력한 이름이 어셈블리 어셈블리 수준에서이 특성을 명시적으로 적용 되지 않습니다 하에 완전 신뢰가 부여 되는 다른 어셈블리에서 호출할 수 있습니다.By default, if a strong-named, assembly does not explicitly apply this attribute at the assembly level, it can be called only by other assemblies that are granted full trust. 이 제한은 어셈블리의 공개적으로 액세스할 수 있는 모든 클래스에서 public 또는 protected 메서드를 FullTrust에 대 한 LinkDemand 배치 하 여 적용 됩니다.This restriction is enforced by placing a LinkDemand for FullTrust on every public or protected method on every publicly accessible class in the assembly. 부분적으로 신뢰할 수 있는 코드에서 호출 하려는 어셈블리는 AllowPartiallyTrustedCallersAttribute을 사용 하 여 의도를 선언할 수 있습니다.Assemblies that are intended to be called by partially trusted code can declare their intent through the use of AllowPartiallyTrustedCallersAttribute. 의 C# 선언 예는 [assembly:AllowPartiallyTrustedCallers]입니다. Visual Basic의 예제는 <assembly:AllowPartiallyTrustedCallers>입니다.An example of the declaration in C# is [assembly:AllowPartiallyTrustedCallers]; an example in Visual Basic is <assembly:AllowPartiallyTrustedCallers>.

주의

이 어셈블리 수준 특성이 있으면 보안 검사 FullTrustLinkDemand 기본 동작을 수행할 수 없으며, 어셈블리를 부분적으로 또는 완전히 신뢰할 수 있는 다른 어셈블리에서 호출할 수 있습니다.The presence of this assembly-level attribute prevents the default behavior of placing FullTrustLinkDemand security checks, and makes the assembly callable from any other (partially or fully trusted) assembly.

APTCA 특성 존재 하는 경우 다른 모든 보안 확인 함수 의도 대로 존재 하는 모든 클래스 수준 또는 메서드 수준의 선언적 보안 특성을 포함 합니다.When the APTCA attribute is present, all other security checks function as intended, including any class-level or method-level declarative security attributes that are present. 이 특성에는 수요를 암시적, 완전히 신뢰할 수 있는 호출자만 차단합니다.This attribute blocks only the implicit, fully trusted caller demand.

이는 선언적 보안 특성이 아니지만 일반 특성입니다 .이 특성은 System.Security.Permissions.SecurityAttribute가 아닌 System.Attribute에서 파생 됩니다.This is not a declarative security attribute, but a regular attribute (it derives from System.Attribute, not from System.Security.Permissions.SecurityAttribute).

자세한 내용은 부분적으로 신뢰할 수 있는 코드에서 라이브러리를 사용 하 여입니다.For more information, see Using Libraries from Partially Trusted Code.
