初始化 FileSystemAccessRule 类的新实例。

FileSystemAccessRule(IdentityReference, FileSystemRights, InheritanceFlags, PropagationFlags, AccessControlType)	使用以下内容初始化 FileSystemAccessRule 类的新实例：对用户帐户的引用、指定与访问规则关联的操作的类型的值、确定如何继承权限的值、确定如何传播权限的值，以及指定是允许还是拒绝该操作的值。

FileSystemAccessRule(IdentityReference, FileSystemRights, AccessControlType)

使用以下内容初始化 FileSystemAccessRule 类的新实例：对用户帐户的引用、指定与访问规则关联的操作的类型的值，以及指定是允许还是拒绝该操作的值。

public:
 FileSystemAccessRule(System::Security::Principal::IdentityReference ^ identity, System::Security::AccessControl::FileSystemRights fileSystemRights, System::Security::AccessControl::AccessControlType type);

public FileSystemAccessRule (System.Security.Principal.IdentityReference identity, System.Security.AccessControl.FileSystemRights fileSystemRights, System.Security.AccessControl.AccessControlType type);

new System.Security.AccessControl.FileSystemAccessRule : System.Security.Principal.IdentityReference * System.Security.AccessControl.FileSystemRights * System.Security.AccessControl.AccessControlType -> System.Security.AccessControl.FileSystemAccessRule

Public Sub New (identity As IdentityReference, fileSystemRights As FileSystemRights, type As AccessControlType)

参数

identity: IdentityReference

封装对用户帐户的引用的 IdentityReference 对象。

fileSystemRights: FileSystemRights

FileSystemRights 值之一，该值指定与访问规则关联的操作的类型。

type: AccessControlType

AccessControlType 值之一，该值指定是允许还是拒绝该操作。

例外

ArgumentException

identity 参数不是一个 IdentityReference 对象。

ArgumentNullException

identity 参数为 null。

ArgumentOutOfRangeException

一个错误枚举被传递给 type 参数。

注解

使用此构造函数创建可以使用或 DirectorySecurity 类持久保存FileSecurity的访问控制规则。访问控制规则定义用户帐户权限，用于确定在运行 Windows Microsoft的计算机上允许或禁止哪些操作。

    // Get a FileSecurity object that represents the 
    // current security settings.
    FileSecurity^ fSecurity = File::GetAccessControl(fileName);

    // Add the FileSystemAccessRule to the security settings. 
    fSecurity->AddAccessRule(gcnew FileSystemAccessRule
                                   (account,rights, controlType));

    // Set the new access settings.
    File::SetAccessControl(fileName, fSecurity);
}

// Removes an ACL entry on the specified file for the specified account.

void RemoveFileSecurity(String^ fileName, String^ account,
