範例

下列範例示範如何使用 ApplicationBase 屬性來設定元件載入器開始探查的位置，讓元件載入至新的應用程式域。

注意

您必須確定您指定的資料夾存在。

using namespace System;

int main()
{
    AppDomain^ root = AppDomain::CurrentDomain;

    AppDomainSetup^ setup = gcnew AppDomainSetup();
    setup->ApplicationBase = 
        root->SetupInformation->ApplicationBase + "MyAppSubfolder\\";

    AppDomain^ domain = AppDomain::CreateDomain("MyDomain", nullptr, setup);

    Console::WriteLine("Application base of {0}:\r\n\t{1}", 
        root->FriendlyName, root->SetupInformation->ApplicationBase);
    Console::WriteLine("Application base of {0}:\r\n\t{1}", 
        domain->FriendlyName, domain->SetupInformation->ApplicationBase);

    AppDomain::Unload(domain);
}

/* This example produces output similar to the following:

Application base of MyApp.exe:
        C:\Program Files\MyApp\
Application base of MyDomain:
        C:\Program Files\MyApp\MyAppSubfolder\
 */

using System;

class ADSetupInformation
{
    static void Main()
    {
        AppDomain root = AppDomain.CurrentDomain;

        AppDomainSetup setup = new AppDomainSetup();
        setup.ApplicationBase =
            root.SetupInformation.ApplicationBase + @"MyAppSubfolder\";

        AppDomain domain = AppDomain.CreateDomain("MyDomain", null, setup);

        Console.WriteLine("Application base of {0}:\r\n\t{1}",
            root.FriendlyName, root.SetupInformation.ApplicationBase);
        Console.WriteLine("Application base of {0}:\r\n\t{1}",
            domain.FriendlyName, domain.SetupInformation.ApplicationBase);

        AppDomain.Unload(domain);
    }
}

/* This example produces output similar to the following:

Application base of MyApp.exe:
        C:\Program Files\MyApp\

open System

let root = AppDomain.CurrentDomain

let setup = AppDomainSetup()
setup.ApplicationBase <-
    root.SetupInformation.ApplicationBase + @"MyAppSubfolder\"

let domain = AppDomain.CreateDomain("MyDomain", null, setup)

printfn $"Application base of {root.FriendlyName}:\r\n\t{root.SetupInformation.ApplicationBase}"
printfn $"Application base of {domain.FriendlyName}:\r\n\t{domain.SetupInformation.ApplicationBase}"

AppDomain.Unload domain

(* This example produces output similar to the following:

Application base of MyApp.exe:
        C:\Program Files\MyApp\
Application base of MyDomain:
        C:\Program Files\MyApp\MyAppSubfolder\
 *)

Class ADSetupInformation

    Shared Sub Main()

        Dim root As AppDomain = AppDomain.CurrentDomain

        Dim setup As New AppDomainSetup()
        setup.ApplicationBase = _
            root.SetupInformation.ApplicationBase & "MyAppSubfolder\"

        Dim domain As AppDomain = AppDomain.CreateDomain("MyDomain", Nothing, setup)

        Console.WriteLine("Application base of {0}:" & vbCrLf & vbTab & "{1}", _
            root.FriendlyName, root.SetupInformation.ApplicationBase)
        Console.WriteLine("Application base of {0}:" & vbCrLf & vbTab & "{1}", _
            domain.FriendlyName, domain.SetupInformation.ApplicationBase)

        AppDomain.Unload(domain)
    End Sub
End Class

' This example produces output similar to the following:
'
'Application base of MyApp.exe:
'        C:\Program Files\MyApp\
'Application base of MyDomain:
'        C:\Program Files\MyApp\MyAppSubfolder\

備註

應用程式基底目錄是元件管理員開始探查元件的所在位置。

屬性 ApplicationBase 可能會影響授與應用程式域的許可權。 例如，源自本機電腦的應用程式域通常會根據其來源位置接收完全信任。 不過，如果 ApplicationBase 的 屬性 AppDomain 設定為內部網路目錄的完整名稱，則 ApplicationBase 此設定會將授與應用程式域的許可權限制為 LocalIntranet 授與，即使應用程式域實際上源自本機電腦也一樣。
