+### 9、多平台代码参考,使用自定义SqliteProvider,例如Sqlite用Microsoft.Data.Sqlite或者反射Mono.Data.Sqlite.
+
+[arm/树莓派](https://github.com/densen2014/FreeSqlDemos/tree/master/ARM_ConsoleApp)
+
+1.添加包
+
+```
+<PackageReference Include="FreeSql.Provider.Sqlite" Version="3.0.100" />
+<PackageReference Include = "Microsoft.Data.Sqlite" Version="6.0.3" />
+```
+
+2.代码
+
+```
+Microsoft.Data.Sqlite.SqliteConnection _database = new Microsoft.Data.Sqlite.SqliteConnection($"Data Source=document.db");
+
+var fsql = new FreeSql.FreeSqlBuilder()
+        .UseConnectionFactory(FreeSql.DataType.Sqlite, () => _database, typeof(FreeSql.Sqlite.SqliteProvider<>))
+        .UseAutoSyncStructure(true)
+        .UseNoneCommandParameter(true) //必须开启,因为Microsoft.Data.Sqlite内插处理有bug
+        .UseMonitorCommand(cmd => Console.Write(cmd.CommandText))
+        .Build();
+```
+
+[UWP](https://github.com/densen2014/FreeSqlDemos/tree/master/UWP1)
+
+```
+using System.Data.SQLite;
+
+string dbpath = Path.Combine(ApplicationData.Current.LocalFolder.Path, "sqliteSample.db");
+SQLiteConnection _database = new SQLiteConnection($"Data Source={dbpath}");
+var fsql = new FreeSql.FreeSqlBuilder()
+           `.UseConnectionFactory(FreeSql.DataType.Sqlite, () => _database, typeof(FreeSql.Sqlite.SqliteProvider<>))
+           `.Build();
+```
+
+[Xamarin Forms,代码较多](https://github.com/densen2014/FreeSqlDemos/tree/master/xamarinFormApps)
+主程序,接口获取rovider,各个平台自己实现.
+```
+if (Device.RuntimePlatform == Device.iOS || Device.RuntimePlatform == Device.Android)
+{
+   fsql = new FreeSql.FreeSqlBuilder()
+          .UseConnectionFactory(FreeSql.DataType.Sqlite, () => DependencyService.Get<ISQLite>().GetConnectionSqlite("document"), typeof(FreeSql.Sqlite.SqliteProvider<>))
+          .UseNoneCommandParameter(true)
+          .Build();
+}
+```
+
+[iOS部分](https://github.com/densen2014/FreeSqlDemos/blob/master/xamarinFormApps/xamarinFormApp.iOS/SQLite_iOS.cs)
+
+[安卓部分](https://github.com/densen2014/FreeSqlDemos/blob/master/xamarinFormApps/xamarinFormApp.Android/SQLite_droid.cs)
