InstallContext.Parameters 屬性

定義

取得當執行 InstallUtil.exe 時所輸入的命令列參數。

public:
 property System::Collections::Specialized::StringDictionary ^ Parameters { System::Collections::Specialized::StringDictionary ^ get(); };
public System.Collections.Specialized.StringDictionary Parameters { get; }
member this.Parameters : System.Collections.Specialized.StringDictionary
Public ReadOnly Property Parameters As StringDictionary

屬性值

StringDictionary,表示當執行安裝可執行檔時所輸入的命令列參數。

範例

這個範例是 類別概觀類別中範例的 InstallContext 摘錄。

此範例會 Parameters 擷取 屬性,以查看使用者是否已輸入任何命令行自變數。 它也會使用 IsParameterTrue 方法來找出 LogtoConsole 是否已設定 參數。 如果是 yes,則會使用 LogMessage 方法將狀態消息寫入安裝記錄檔和控制台。

StringDictionary^ myStringDictionary = myInstallContext->Parameters;
if ( myStringDictionary->Count == 0 )
{
   Console::Write( "No parameters have been entered in the command line " );
   Console::WriteLine( "hence, the install will take place in the silent mode" );
}
else
{
   // Check whether the "LogtoConsole" parameter has been set.
   if ( myInstallContext->IsParameterTrue( "LogtoConsole" ) )
   {
      // Display the message to the console and add it to the logfile.
      myInstallContext->LogMessage( "The 'Install' method has been called" );
   }
}
StringDictionary myStringDictionary = myInstallContext.Parameters;
if( myStringDictionary.Count == 0 )
{
   Console.WriteLine( "No parameters have been entered in the command line "
      +"hence, the install will take place in the silent mode" );
}
else
{
   // Check whether the "LogtoConsole" parameter has been set.
   if( myInstallContext.IsParameterTrue( "LogtoConsole" ) == true )
   {
      // Display the message to the console and add it to the logfile.
      myInstallContext.LogMessage( "The 'Install' method has been called" );
   }
}
Dim myStringDictionary As StringDictionary = myInstallContext.Parameters
If myStringDictionary.Count = 0 Then
   Console.WriteLine("No parameters have been entered in the command line" + _
               "hence, the install will take place in the silent mode")
Else
   ' Check wether the "LogtoConsole" parameter has been set.
   If myInstallContext.IsParameterTrue("LogtoConsole") = True Then
      ' Display the message to the console and add it to the logfile.
      myInstallContext.LogMessage("The 'Install' method has been called")
   End If
End If

備註

建立新的 InstallContext 時,命令行參數會剖析成 Parameters 屬性。 索引鍵和參數的值都是字串。
