How to remove HTML from a text string in C# .NET Framework

Even with security measures in place, scripting attacks can be a real danger. One very simple, yet powerful method to guard against this is to filter out HTML code from user submitted data. The good news — this task has never been easier.

Let’s start the ball rolling with a quick installation of Cloudmersive’s API Client via NuGet. This just means pasting the following command right into your console of the Package Manager.

Install-Package Cloudmersive.APIClient.NET.DocumentAndDataConvert -Version 2.2.0

Now we are ready to call our function, which is called EditTextRemoveHtml:

using System;
using System.Diagnostics;
using Cloudmersive.APIClient.NET.DocumentAndDataConvert.Api;
using Cloudmersive.APIClient.NET.DocumentAndDataConvert.Client;
using Cloudmersive.APIClient.NET.DocumentAndDataConvert.Model;
namespace Example
{
public class EditTextRemoveHtmlExample
{
public void main()
{
// Configure API key authorization: Apikey
Configuration.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 EditTextApi();
var request = new RemoveHtmlFromTextRequest(); // RemoveHtmlFromTextRequest | Input request
try
{
// Remove HTML from text string
RemoveHtmlFromTextResponse result = apiInstance.EditTextRemoveHtml(request);
Debug.WriteLine(result);
}
catch (Exception e)
{
Debug.Print("Exception when calling EditTextApi.EditTextRemoveHtml: " + e.Message );
}
}
}
}

The API will solve the problem for us, removing any HTML present, leaving us with pure text, cleaned of formatting.
