URL Encode and Decode in ASP.NET Core

  • For ASP.NET Core 2.0+ just add System.Net namespace – WebUtility class is shipped as part of System.Runtime.Extensions nuget package, that is referenced by default in ASP.NET Core project.

  • For the previous version add Microsoft.AspNetCore.WebUtilities nuget package.

Then the WebUtility class will be available for you:

public static class WebUtility
{
    public static string UrlDecode(string encodedValue);
    public static string UrlEncode(string value);
}
