Build ASP.NET Core Blazor C# apps that integrate with real-time MySQL data using standard SQL.
Blazor is a framework for developing modern, client-side web UIs using .NET technology. Instead of coding in JavaScript, developers can use the familiar C# language and .NET libraries to build app UIs.
The CData ADO.NET Provider for MySQL can be used with standard ADO.NET interfaces, such as LINQ and Entity Framework, to interact with live MySQL data. Since Blazor supports .NET Core, developers can use CData ADO.NET Providers in Blazor apps. In this article, we will guide you to build a simple Blazor app that talks to MySQL using standard SQL queries.
Install the CData ADO.NET Provider for MySQL
CData ADO.NET Providers allow users to access MySQL just like they would access SQL Server, using simple SQL queries.
Install the MySQL ADO.NET Data Provider from the CData website or from NuGet. Search NuGet for "MySQL ADO.NET Data Provider."
Create a MySQL-Connected Blazor App
Start by creating a Blazor project that references the CData ADO.NET Provider for MySQL
- Create a Blazor project on Visual Studio.
- From the Solution Explorer, right click Dependencies, then click Add Project Reference.
- In the Reference Manager, click the Browse button, and choose the .dll file of the installed ADO.NET Provider (e.g. System.Data.CData.MySQL.dll, typically located at C:\Program Files\CData\CData ADO.NET Provider for MySQL\lib etstandard2.0).
SELECT MySQL Data from the Blazor App
- Open the Index.razor file from the Project page.
- In a MySQLConnection object, set the connection string:
The Server and Port properties must be set to a MySQL server. If IntegratedSecurity is set to false, then User and Password must be set to valid user credentials. Optionally, Database can be set to connect to a specific database. If not set, tables from all databases will be returned.
For example: User=myUser;Password=myPassword;Database=NorthWind;Server=myServer;Port=3306;
- The code below creates a simple Blazor app for displaying MySQL data, using standard SQL to query MySQL just like SQL Server.
@page "/" @using System.Data; @using System.Data.CData.MySQL; <h1>Hello, world!</h1> Welcome to your Data app. <div class="row"> <div class="col-12"> @using (MySQLConnection connection = new MySQLConnection( "User=myUser;Password=myPassword;Database=NorthWind;Server=myServer;Port=3306;")) { var sql = "SELECT ShipName, Freight FROM Orders"; var results = new DataTable(); MySQLDataAdapter dataAdapter = new MySQLDataAdapter(sql, connection); dataAdapter.Fill(results); <table class="table table-bordered"> <thead class="thead-light"> <tr> @foreach (DataColumn item in results.Rows[0].Table.Columns) { <th scope="col">@item.ColumnName</th> } </tr> </thead> <tbody> @foreach (DataRow row in results.Rows) { <tr> @foreach (var column in row.ItemArray) { <td>@column.ToString()</td> } </tr> } </tbody> </table> } </div> </div>
- Rebuild and run the project. The ADO.NET Provider renders MySQL data as an HTML table in the Blazor app.
At this point, you have a MySQL-connected Blazor app, capable of working with live MySQL data just like you would work with a SQL Server instance. Download a free, 30-day trial and start working with live MySQL data in your Blazor apps today.
