如何开放UnmanagedCode 权限？

[chenlin2000]

请问vb。net中如何开放UnmanagedCode 权限

[pxjhy]

获取或设置一个值，该值指示是否声明了调用非托管代码的权限。

[Visual Basic]
Public Property UnmanagedCode As Boolean

如果声明了调用非托管代码的权限，则为 true；否则为 false。

示例
[Visual Basic]
' Set the Assertion,UnmanagedCode, ControlAppDomain, ControlDomainPolicy, ontrolEvidence,
' ControlPolicy, ControlPrincipal, ControlThread, Execution, Flags, Infrastructure,
' RemotingConfiguration, SerializationFormatter, and SkipVerification properties.
<SecurityPermissionAttribute(SecurityAction.Deny, Assertion:=True), _
SecurityPermissionAttribute(SecurityAction.Deny, ControlAppDomain:=True), _
SecurityPermissionAttribute(SecurityAction.Deny, ControlDomainPolicy:=True), _
SecurityPermissionAttribute(SecurityAction.Deny, ControlEvidence:=True), _
SecurityPermissionAttribute(SecurityAction.Deny, ControlPolicy:=True), _
SecurityPermissionAttribute(SecurityAction.Deny, ControlPrincipal:=True), _
SecurityPermissionAttribute(SecurityAction.Deny, ControlThread:=True), _
SecurityPermissionAttribute(SecurityAction.Deny, Execution:=True), _
SecurityPermissionAttribute(SecurityAction.Deny, Flags:=SecurityPermissionFlag.NoFlags), _
SecurityPermissionAttribute(SecurityAction.Deny, Infrastructure:=True), _
SecurityPermissionAttribute(SecurityAction.Deny, RemotingConfiguration:=True), _
SecurityPermissionAttribute(SecurityAction.Deny, SerializationFormatter:=True), _
SecurityPermissionAttribute(SecurityAction.Deny, SkipVerification:=True), _
SecurityPermissionAttribute(SecurityAction.Deny, UnmanagedCode:=True)> _
Public Shared Sub DenySecurityPermissions()
