解決vs dpi問題

1. 支援.net framework : 

 NET Framework improves WinForms' DPI support starting at 4.7. So I changed the runtime of the program to 4.7.2 (Windows 10 1803 or more comes with it) 

2. app.config 加上 

<?xml version="1.0" encoding="utf-8"?>

<configuration>

    <startup> 

        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.7.2"/>

    </startup>

    <System.Windows.Forms.ApplicationConfigurationSection>

  <add key="DpiAwareness" value="PerMonitorV2"/>

</System.Windows.Forms.ApplicationConfigurationSection>

</configuration>
