Upgrading from V1? Read This: https://github.com/zerobounce/zerobounce-dotnet-api-v2/blob/master/upgrading.md

The ValidateEmail and GetCredit methods return objects from which you can retrieve properties that return the relevant information.

You can also easily consume and keep it updated within your Visual Studio Project with Nuget Package Manager: https://www.nuget.org/packages/ZeroBounceAPIWrapperv2/

Property Values
api_key Located in your account.
emailToValidate The email address your validating.
ip_address [optional] The IP Address the email address was captured from
requestTimeOut [optional] Timeout settings in milliseconds, setting this enables you to control how long you are willing to wait for to send the request to the API. When the timeout occurs an "Unknown" result is returned.

C# Example usage:

 var zeroBounceAPI = new ZeroBounce.ZeroBounceAPI();

//set input parameters
zeroBounceAPI.api_key = "Your API Key"; //Required
zeroBounceAPI.emailToValidate = "Email address you are validating"; //Required
zeroBounceAPI.ip_address = "IP address the email signed up with"; //Optional

//Depending on how you use the API, you might want it to time out faster, for example on a registration screen. 
//Normally the API will return results very fast, but a small percentage of mail servers take
//upwards of 20+ seconds to respond. 
//If the API times out, it will return a status of "Unknown" and a sub_status of "timeout_exceeded"  

zeroBounceAPI.readTimeOut = 200000;// "Any integer value in milliseconds
zeroBounceAPI.requestTimeOut = 150000; // "Any integer value in milliseconds

//validate email and assign results to an object
var apiProperties = zeroBounceAPI.ValidateEmail();

//check credits and assign results to an object
var apiCredits= zeroBounceAPI.GetCredits();

//use the properties to make decisions on
switch (apiProperties.status)
  {
      case "Invalid":
          Console.WriteLine("invalid");
          break;
      case "Valid":
          Console.WriteLine("valid");
          break;
      default:
          Console.WriteLine(apiProperties.status);
          break;
  }
