通过

ComponentInstaller.IsEquivalentInstaller 方法

  • 项目

确定指定的安装程序是否与此安装程序安装相同的对象。

**命名空间:**System.Configuration.Install
**程序集:**System.Configuration.Install（在 system.configuration.install.dll 中）

语法

声明
Public Overridable Function IsEquivalentInstaller ( _
    otherInstaller As ComponentInstaller _
) As Boolean
用法
Dim instance As ComponentInstaller
Dim otherInstaller As ComponentInstaller
Dim returnValue As Boolean

returnValue = instance.IsEquivalentInstaller(otherInstaller)

public virtual bool IsEquivalentInstaller (
    ComponentInstaller otherInstaller
)

public:
virtual bool IsEquivalentInstaller (
    ComponentInstaller^ otherInstaller
)

public boolean IsEquivalentInstaller (
    ComponentInstaller otherInstaller
)

public function IsEquivalentInstaller (
    otherInstaller : ComponentInstaller
) : boolean

参数

  • otherInstaller
    要比较的安装程序。

返回值

如果此安装程序和 otherInstaller 参数指定的安装程序安装相同的对象，则为 true；否则为 false。

备注

通常，仅当此安装程序和 otherInstaller 参数指定的安装程序安装相同的对象时，IsEquivalentInstaller 才返回 true。在这种情形下，对任一安装程序调用 Install 或 Uninstall 方法，都会导致相同的系统状态。

示例

下面的示例定义类 MyInstallClass，该类创建事件日志，并将事件日志组件的属性复制到 EventLogInstaller 对象中。它还检查 ServiceInstaller 对象是否可以处理与 EventLogInstaller 相同类型的安装。

Dim myServiceInstaller As New ServiceInstaller()
' Check whether 'ServiceInstaller' object can handle the same 
' kind of installation as 'EventLogInstaller' object.
If myEventLogInstaller.IsEquivalentInstaller(myServiceInstaller) Then
   Console.WriteLine("'ServiceInstaller' can handle the same kind" + _
                              " of installation as EventLogInstaller")
Else
   Console.WriteLine("'ServiceInstaller' can't handle the same" + _
                        " kind of installation as 'EventLogInstaller'")
End If

ServiceInstaller myServiceInstaller = new  ServiceInstaller();
// Check whether 'ServiceInstaller' object can handle the same 
// kind of installation as 'EventLogInstaller' object.
if(myEventLogInstaller.IsEquivalentInstaller(myServiceInstaller))
{
   Console.WriteLine("'ServiceInstaller' can handle the same kind" 
                     +" of installation as EventLogInstaller");
}
else
{
    Console.WriteLine("'ServiceInstaller' can't handle the same" 
                 +" kind of installation as 'EventLogInstaller'");
}

ServiceInstaller^ myServiceInstaller = gcnew ServiceInstaller;
// Check whether 'ServiceInstaller' object can handle the same
// kind of installation as 'EventLogInstaller' object.
if ( myEventLogInstaller->IsEquivalentInstaller( myServiceInstaller ) )
{
   Console::WriteLine( "'ServiceInstaller' can handle the same kind " +
      "of installation as EventLogInstaller" );
}
else
{
   Console::WriteLine( "'ServiceInstaller' can't handle the same " +
      "kind of installation as 'EventLogInstaller'" );
}

ServiceInstaller myServiceInstaller = new ServiceInstaller();
// Check whether 'ServiceInstaller' object can handle the same 
// kind of installation as 'EventLogInstaller' object.
if (myEventLogInstaller.IsEquivalentInstaller(myServiceInstaller)) {
    Console.WriteLine("'ServiceInstaller' can handle the same kind"
        + " of installation as EventLogInstaller");
}
else {
    Console.WriteLine("'ServiceInstaller' can't handle the same"
        + " kind of installation as 'EventLogInstaller'");
}
