C#笔记

ConfigurationManager.AppSettings["LanguageSetting"]; //获取     <add key="ANT8" value="0"/> value

ConfigurationManager.ConnectionStrings["EleScale.Properties.Settings.RFIDDB_HRConnectionString"].ConnectionString;  通过name 获取connectionString的值

<add name="EleScale.Properties.Settings.RFIDDB_HRConnectionString" connectionString="Data Source=.;Initial Catalog=RFIDDB;Persist Security Info=True;User ID=sa;Password=123;Integrated Security=False" providerName="System.Data.SqlClient"/>

 

MAUI中这个很重要可以连通API不添加就连接不了

[Application(UsesCleartextTraffic = true)]
public class MainApplication : MauiApplication
{
public MainApplication(IntPtr handle, JniHandleOwnership ownership)
: base(handle, ownership)
{
}

protected override MauiApp CreateMauiApp() => MauiProgram.CreateMauiApp();
}
