Public ReadOnly Property Parameters As StringDictionary

属性值

StringDictionary

一个 StringDictionary，它代表运行可执行安装文件时输入的命令行参数。

示例

此示例是类的类概述中示例的 InstallContext 摘录。

该示例检索 Parameters 属性，以查看用户是否已输入任何命令行参数。 它还使用 IsParameterTrue 方法来确定参数是否已 LogtoConsole 设置。 如果 yes为 ，则使用 LogMessage 方法将状态消息写入安装日志文件和控制台。

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

注解

创建新 InstallContext 时，命令行参数将分析为 Parameters 属性。 参数的键和值都是字符串。
