C# - Xero API getting the C# code sample working for Private Applications with NuGet
If you don't want to use the NuGet package you can also compile from source (see Xero API compiling the C# code sample from source for Private Applications)
Never having used C# or Visual Studio before I struggled to get the C# code samples working for Xero API, I list my steps here to help others
1) Read through Xero's getting started guide (http://developer.xero.com/documentation/getting-started/getting-started-guide/) but then follow the steps below.
2) Install openssl (I installed on my windows laptop) and generate a public/private pair of keys (see http://developer.xero.com/documentation/advanced-docs/public-private-keypair/) remember the password during the third "export" command. The file we are interested in is:
public_privatekey.pfx3) Open Visual Studio (I have 2013) choose File->New->Project then Templates->Visual C#->Store Apps->Windows Desktop->Console Application
4) Referencing the instructions on https://github.com/XeroAPI/Xero-Net in Visual Studio->Tools->NuGet Package Manager->Package Manager Console at the prompt Bottom of screen) type:
Install-Package Xero.API.SDK5) in the open file Program.cs add the following to the top
using System.Security.Cryptography.X509Certificates;using Xero.Api;using Xero.Api.Core;using Xero.Api.Example.Applications;using Xero.Api.Example.Applications.Private;using Xero.Api.Infrastructure.OAuth;using Xero.Api.Serialization;5) inside main() edit as appropriate and add the following:
X509Certificate2 cert = new X509Certificate2(@"C:OpenSSL-Win32binpublic_privatekey.pfx", "testitout"); var private_app_api = new XeroCoreApi("https://api.xero.com", new PrivateAuthenticator(cert), new Consumer("XE7A2PCGHNEQZYTBKNNT05NAIECSXS", "ILCZGF2ME9CJDQYRZW0ADYI4UWYWBJ"), null, new DefaultMapper(), new DefaultMapper()); var org = private_app_api.Organisation; Console.WriteLine("Org Name: " + org.Name); var user = new ApiUser { Name = Environment.MachineName };
6) Click "Build"->"Build Solution" make sure there are no errors
7) Click "Debug"->"Start without Debugging"
you should get a popup window's console showing the "Demo Company name"
If you get a crash with the error:
System.Security.Cryptography.CryptographicException was unhandled HResult=-2147024810 Message=The specified network password is not correct. Source=mscorlibHere's some extra code demonstrating how to fetch and loop through invoices:
or use a foreach loop:
