PolicyStatement(PermissionSet)

Source:

PolicyStatement.cs

注意

Code Access Security is not supported or honored by the runtime.

使用指定的 PolicyStatement 初始化 PermissionSet 类的新实例。

public:
 PolicyStatement(System::Security::PermissionSet ^ permSet);

[System.Obsolete("Code Access Security is not supported or honored by the runtime.", DiagnosticId="SYSLIB0003", UrlFormat="https://aka.ms/dotnet-warnings/{0}")]
public PolicyStatement (System.Security.PermissionSet permSet);

[<System.Obsolete("Code Access Security is not supported or honored by the runtime.", DiagnosticId="SYSLIB0003", UrlFormat="https://aka.ms/dotnet-warnings/{0}")>]
new System.Security.Policy.PolicyStatement : System.Security.PermissionSet -> System.Security.Policy.PolicyStatement

Public Sub New (permSet As PermissionSet)

参数

permSet

PermissionSet

用于初始化新实例的 PermissionSet。

属性

ObsoleteAttribute

示例

下面的代码示例演示如何使用 PolicyStatement 构造函数。 此代码示例是为 PolicyStatement 类提供的一个更大示例的一部分。

PermissionSet^ permissions = gcnew PermissionSet(
   PermissionState::Unrestricted );
permissions->AddPermission( gcnew SecurityPermission(
   SecurityPermissionFlag::Execution ) );
permissions->AddPermission( gcnew ZoneIdentityPermission(
   SecurityZone::MyComputer ) );

// Create a policy statement based on the newly created permission
// set.
PolicyStatement^ policyStatement = gcnew PolicyStatement(
   permissions );

PermissionSet permissions 
    = new PermissionSet(PermissionState.Unrestricted);
permissions.AddPermission(
    new SecurityPermission(SecurityPermissionFlag.Execution));
permissions.AddPermission(
    new ZoneIdentityPermission(SecurityZone.MyComputer));

// Create a policy statement based on the newly created permission
// set.
PolicyStatement policyStatement = new PolicyStatement(permissions);

Dim permissions As New PermissionSet(PermissionState.Unrestricted)

permissions.AddPermission( _
    New SecurityPermission(SecurityPermissionFlag.Execution))
permissions.AddPermission( _
    New ZoneIdentityPermission(SecurityZone.MyComputer))

' Instantiate a new policy statement with specified permission set.
Dim policyStatement As New PolicyStatement(permissions)

PolicyStatement(PermissionSet, PolicyStatementAttribute)

Source:

PolicyStatement.cs

new System.Security.Policy.PolicyStatement : System.Security.PermissionSet * System.Security.Policy.PolicyStatementAttribute -> System.Security.Policy.PolicyStatement

Public Sub New (permSet As PermissionSet, attributes As PolicyStatementAttribute)

参数

permSet

PermissionSet

用于初始化新实例的 PermissionSet。

attributes

PolicyStatementAttribute

PolicyStatementAttribute 值的按位组合。

属性

ObsoleteAttribute
