Choose a method based on what type of data the column contains. You can use similar methods such as GetDataTime and GetBoolean. It accepts an integer value that represents the zero-based column ordinal of the data that you want. The GetString method returns the value of the specified column as a string. It returns true if there are rows left, otherwise it returns false. The Read method advances through the rows of returned data.
SqliteDataReader query = selectCommand.ExecuteReader() Using (var db = new SqliteConnection($"Filename=")) public static void AddData(string inputText)
#USE DB SQLITE CODE#
This code uses parameters in the query to prevent SQL injection attacks. public App()Īdd a method to the DataAccess class that inserts data into the SQLite database. This will ensure that the database is created or opened each time the app starts. In the constructor of the file of your project, call the InitializeDatabase method of the DataAccess class. In a production application, connection information such as the database filename should be stored in app configuration rather than hard-coded (see Adding Azure App Configuration by using Visual Studio Connected Services). In this example, we name the database sqlliteSample.db but you can use whatever name you want as long as you use that name in all SqliteConnection objects that you instantiate. This code creates the SQLite database and stores it in the application's local data store.
#USE DB SQLITE WINDOWS#
All other Windows apps should access ApplicationData members via the ApplicationDataManager class. The code above that uses ApplicationData members will only work for packaged apps running in an app container. Open the DataAccess class in your project and make that class static.

We are going to use the version of SQLite that's included with Windows.Ĭhoose the Browse tab, search for the package, and then install the latest stable version.Īdd and retrieve data in a SQLite databaseģ️⃣ Insert data into the SQLite database.Ĥ️⃣ Retrieve data from the SQLite database.ĥ️⃣ Add a basic user interface. You can use the version of SQLite that is included with Windows or if you have some reason to use a specific version of SQLite, you can include the SQLite library in your package. Right-click the solution, and then click Manage NuGet Packages for Solution.Īt this point, you have a choice. NET class library project to contain your data access code, but we won't use one in our example. If you plan to share your data access logic with other client code, you can use a. Let's start by adding a class to your project named DataAccess. ✔️ App load time has the potential to be faster because most likely, the SDK version of SQLite will already be loaded into memory. The Windows version of SQLite is maintained by Microsoft in coordination with. ✔️ Prevents you from having to push a new version of your app to users in the event that SQLite publishes critical fixes to bugs and security vulnerabilities in SQLite.
#USE DB SQLITE DOWNLOAD#
✔️ Reduces the size of your application because you don't have to download the SQLite binary, and then package it as part of your application. Instead, your app can use the version of SQLite that comes installed with Windows. We'll start with a basic Windows App SDK project, and then install the SQLite NuGet package.Īll supported versions of Windows support SQLite, so your app does not have to package SQLite libraries. The rest of this guide helps you to use this library. Microsoft actively maintains these implementations, and they provide an intuitive wrapper around the low-level native SQLite API.
The library implements the interfaces in the namespace. To try it out, see Getting Started with EF Core. NET apps, you can use the same code in your Windows App SDK app and it will work with appropriate changes to the connection string. If you've already used this framework to work with data in other. Entity Framework CoreĮntity Framework (EF) is an object-relational mapper that you can use to work with relational data by using domain-specific objects. We recommend that you use either Entity Framework Core or the open-source SQLite library built by Microsoft. ✔️ SQLite works across platforms and architectures.
✔️ SQLite is in the public domain so you can freely use and distribute it with your app. The client and the server run in the same process. It's a code library without any other dependencies. ✔️ SQLite is lightweight and self-contained. Some benefits of using SQLite for local storage
#USE DB SQLITE HOW TO#
This guide shows you how to do it in your Windows App SDK apps. You can use SQLite to store and retrieve data in a lightweight database on the user's device.
