屬性值

StringDictionary

A StringDictionary 代表安裝執行檔執行時輸入的命令列參數。

範例

此範例摘自該類別概述 InstallContext 中的範例。

範例會檢索該 Parameters 屬性，以確認使用者是否輸入了任何命令列參數。 它也會用該 IsParameterTrue 方法來判斷參數是否 LogtoConsole 已被設定。 若 yes，則會使用該 LogMessage 方法將狀態訊息寫入安裝日誌檔及主控台。

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" ))
   {
      // 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

當建立新 InstallContext 檔案時，命令列參數會解析到該 Parameters 屬性中。 鍵和參數值都是字串。
