member this.HelpText : string

Public Overridable ReadOnly Property HelpText As String

Property Value

String

The help text for all the installers in the installer collection, including the description of what the installer does and the command line options for the installation executable, such as the InstallUtil.exe utility, that can be passed to and understood by this installer.

Exceptions

NullReferenceException

One of the installers in the installer collection specifies a null reference instead of help text. A likely cause for this exception is that a field to contain the help text is defined but not initialized.

Examples

The following example demonstrates the HelpText property. This property is defined in the Installer class, which, when called, returns the description of the Installer and the command line options for the installation executable, such as the Installutil.exe utility, that can be passed to and understood by the Installer.

   // Override the property 'HelpText'.
property String^ HelpText 
{
   virtual String^ get() override
   {
      return "Installer Description : This is a sample Installer\n"
           + "HelpText is used to provide useful information about the "
           + "installer.";
   }
}

// Override the property 'HelpText'.
public override string HelpText
{
   get
   {
      return "Installer Description : This is a sample Installer\n"
           + "HelpText is used to provide useful information about the "
           + "installer.";
   }
