vb.net - 使用 VB.Net 在 Windows 防火墙中创建异常

Question

如何使用 vb.net 代码将我的应用程序添加到 Windows 防火墙的例外列表中？

谢谢

Answer 1

Windows Vista 和 7 提供了一个相当强大的防火墙 API，可用于向防火墙添加例外。如果代码以管理员权限运行，则下面的代码将为指定应用程序向 Windows 防火墙添加例外。向您的应用程序添加对%systemroot%\system32\FirewallAPI.dll的引用。

Imports NetFwTypeLib

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

    ' Create the Application we want to add to the exception list
    Dim appType As Type = Type.GetTypeFromProgID("HnetCfg.FwAuthorizedApplication")
    Dim app As INetFwAuthorizedApplication
    app = DirectCast(Activator.CreateInstance(appType), INetFwAuthorizedApplication)

    ' Set the application properties
    app.Name = "Negative0's Sandbox"
    app.ProcessImageFileName = "C:\Users\Negative0\vbsandbox2.exe"
    app.Enabled = True


    ' Get the firewall manager, so we can get the list of authorized apps
    Dim fwMgrType As Type = Type.GetTypeFromProgID("HnetCfg.FwMgr")
    Dim fwMgr As INetFwMgr
    fwMgr = DirectCast(Activator.CreateInstance(fwMgrType), INetFwMgr)

    ' Get the list of authorized applications from the Firewall Manager, so we can add our app to that list
    Dim apps As INetFwAuthorizedApplications
    apps = fwMgr.LocalPolicy.CurrentProfile.AuthorizedApplications
    apps.Add(app)

End Sub
