C sharp asp net web form how to implement apilayer currencylayer

Introduction

ASP.NET is a popular programming language used for building web applications. In this article, we will explore how to implement the currencylayer API in an ASP.NET web form using C#.

up the Project

Before we begin, make sure you have a basic understanding of ASP.NET and have Studio installed on your machine. a new ASP.NET web form project and open the code- file for the web form you want to work with.

Installing the apilayer currencylayer Package

To use the apilayer currencylayer API, we need to install the corresponding NuGet package. Open the NuGet Package Console in Visual Studio and run the following command:

Install-Package apilayer.currencylayer

Initializing the API

Next, we need to initialize the currencylayer API by providing our API access key. You can obtain an access key by signing up on the apilayer website. Once you have the access key, add the following code to your web form's code-behind file:

using apilayer.currencylayer;
// ...

protected void Page_Load(object sender, EventArgs e)
{
     accessKey = "YOUR_ACCESS_KEY";
    CurrencyLayerClient client = new CurrencyLayerClient(accessKey);
    // ...
}

Retrieving Currency Exchange Rates

Now that we have initialized the API, we can start retrieving currency exchange rates. To do this, we will use the GetLiveRatesAsync provided by the CurrencyLayerClient class. Add the following code to your web form's code-behind file:

using apilayer.currencylayer;
// ...

protected  void Page_Load(object sender, EventArgs e)
{
    string accessKey = "YOUR_ACCESS_KEY";
    CurrencyLayerClient client = new CurrencyLayerClient(accessKey);

    var rates = await client.GetLiveRatesAsync();
    // ...
}

Displaying the Currency Exchange Rates

Finally, we can display the retrieved currency exchange rates on our web form. For example, we can bind the rates to a GridView control. Add the following code to your web form's code-behind file:

using apilayer.currencylayer;
// ...

protected async void Page_Load(object sender, EventArgs e)
{
    string accessKey = "YOUR_ACCESS_KEY";
    CurrencyLayerClient client = new CurrencyLayerClient(accessKey);

    var rates = await client.GetLiveRatesAsync();

    GridView1.DataSource = rates.Quotes;
    GridView1.DataBind();
}

Conclusion

In this article, we have learned how to implement the apilayer currencylayer API in an ASP.NET web form using C#. We covered the steps to set up the project, install the necessary package, initialize the API, currency exchange rates, and display them on the web form. With this knowledge, you can now integrate currency exchange functionality into your ASP.NET web applications.
