How to Validate a Domain Name in C# .NET Framework

Today we are going to set up a system for validating domain names using .NET Framework. And by set up, I mean skip all the trouble and toil by using an API. Let’s take a look at how it works.

Install the client with this command.

Install-Package Cloudmersive.APIClient.NET.Validate -Version 2.0.7

Following that, call this function:

using System;using System.Diagnostics;using Cloudmersive.APIClient.NET.Validate.Api;using Cloudmersive.APIClient.NET.Validate.Client;using Cloudmersive.APIClient.NET.Validate.Model;namespace Example{public class DomainCheckExample{public void main(){// Configure API key authorization: ApikeyConfiguration.Default.AddApiKey("Apikey", "YOUR_API_KEY");// Uncomment below to setup prefix (e.g. Bearer) for API key, if needed// Configuration.Default.AddApiKeyPrefix("Apikey", "Bearer");var apiInstance = new DomainApi();var domain = domain_example;  // string | Domain name to check, for example \"cloudmersive.com\".  The input is a string so be sure to enclose it in double-quotes.try{// Validate a domain nameCheckResponse result = apiInstance.DomainCheck(domain);Debug.WriteLine(result);}catch (Exception e){Debug.Print("Exception when calling DomainApi.DomainCheck: " + e.Message );}}}}

And that’s actually all there is to it. Input a domain if you’d like to test it out. The API will do the rest. If you like this simple approach, this same API can do a ton of other validation-related functions, including address and email validation.

There’s an API for that. Cloudmersive is a leader in Highly Scalable Cloud APIs.
