Connect to Mocean Data from Blazor Apps

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 API Driver for ADO.NET can be used with standard ADO.NET interfaces, such as LINQ and Entity Framework, to interact with live Mocean 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 Mocean using standard SQL queries.

Install the CData API Driver for ADO.NET

CData ADO.NET Providers allow users to access Mocean just like they would access SQL Server, using simple SQL queries.

Install the Mocean ADO.NET Data Provider from the CData website or from NuGet. Search NuGet for "Mocean ADO.NET Data Provider."

Create a Mocean-Connected Blazor App

Start by creating a Blazor project that references the CData API Driver for ADO.NET

1. Create a Blazor project on Visual Studio.
👁 Create a Blazor app project.

2. From the Solution Explorer, right click Dependencies, then click Add Project Reference.
3. In the Reference Manager, click the Browse button, and choose the .dll file of the installed ADO.NET Provider (e.g. System.Data.CData.API.dll, typically located at C:\Program Files\CData\CData API Driver for ADO.NET\lib etstandard2.0).
👁 Reference ADO.NET for Mocean .dll in the Blazor app.

SELECT Mocean Data from the Blazor App

1. Open the Index.razor file from the Project page.
2. In a APIConnection object, set the connection string:

   Using API Key Authentication

   Mocean uses API key authentication to control access to the API. To obtain an API Key:

   1. Log in to your Mocean account at https://dashboard.moceanapi.com
   2. Navigate to your account settings or API credentials section
   3. Copy your API Key

   After obtaining your API Key, set the following connection properties:

   • AuthScheme: Set this to APIKey.
   Set the following in the ProfileSettings connection property:
   • APIKey: Set this to your Mocean API Key. This is transmitted as a Bearer token in the Authorization header.

   Example Connection String

   Profile=C:\profiles\Mocean.apip;AuthScheme=APIKey;ProfileSettings='APIKey=your_api_key';
   

   Connecting to Mocean

   Once the authentication is configured, you can connect to Mocean and query data from any of the available tables such as AccountBalance, AccountPricing, MessageStatus, and NumberLookup.

   For example: Profile=C:\profiles\Mocean.apip;AuthScheme=APIKey;ProfileSettings='APIKey=your_api_key';

3. The code below creates a simple Blazor app for displaying Mocean data, using standard SQL to query Mocean just like SQL Server.

    @page "/"
    @using System.Data;
    @using System.Data.CData.API;
    
    <h1>Hello, world!</h1>
    
    Welcome to your Data app.
    
    <div class="row">
    <div class="col-12">
    
    @using (APIConnection connection = new APIConnection(
    "Profile=C:\profiles\Mocean.apip;AuthScheme=APIKey;ProfileSettings='APIKey=your_api_key';"))
    {
    var sql = "SELECT , FROM AccountBalance WHERE = ''";
    var results = new DataTable();
    
    APIDataAdapter dataAdapter = new APIDataAdapter(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>
    

4. Rebuild and run the project. The ADO.NET Provider renders Mocean data as an HTML table in the Blazor app. 👁 Query Mocean from Blazor app.
