What is a HttpRequestException, and how to handle it during external HTTP requests?

Question

Aryan Kumar · Answer

An HttpRequestException is a class in the System.Net.Http namespace that represents an error that occurred during an HTTP request. It can be thrown by the HttpClient class when an error occurs, such as a network error or a server error.
To handle an HttpRequestException during an external HTTP request, you can use a try/catch block. The following code shows an example of how to do this:
C#
try
{
    // Make the HTTP request.
}
catch (HttpRequestException ex)
{
    // Handle the error.
    Console.WriteLine(ex.Message);
}
In this code, the try block makes the HTTP request. If the request fails, the
catch block will be executed and the error message will be displayed in the console.
Here are some additional things to keep in mind when handling HttpRequestExceptions:
The HttpRequestException class has a property called StatusCode that contains the HTTP status code of the error. This property can be used to get more information about the error.The HttpRequestException class also has a property called 
InnerException that contains the inner exception. This property can be used to get the underlying exception that caused the
HttpRequestException.The HttpRequestException class can be handled in the same way as any other exception.
