Property Value

StringDictionary

A StringDictionary that represents the command-line parameters that were entered when the installation executable was run.

Examples

This example is an excerpt of the example in the class overview of InstallContext class.

The sample retrieves the Parameters property to see if any command line argument has been entered by the user. It also uses the IsParameterTrue method to find out if the LogtoConsole parameter has been set. If yes, it will then use the LogMessage method to write status messages to the installation log file and the console.

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

Remarks

When a new InstallContext is created, the command-line parameters are parsed into the Parameters property. Both the keys and the values of the parameters are strings.
