Question

Trying to create a user account in a test. But getting a Object reference is not set to an instanve of an object error when running it.

Here’s my MemberShip provider class, it’s in a class library MyCompany.MyApp.Domain.dll:

using System; using System.Collections.Generic; using System.Web.Security;  namespace MyCompany.MyApp.Domain {     public class MyMembershipProvider : SqlMembershipProvider     {         const int defaultPasswordLength = 8;         private int resetPasswordLength;          public override void Initialize(string name, System.Collections.Specialized.NameValueCollection config)         {             resetPasswordLength = defaultPasswordLength;             string resetPasswordLengthConfig = config['resetPasswordLength'];             if (!String.IsNullOrEmpty(resetPasswordLengthConfig))             {                 config.Remove('resetPasswordLength');                  if (!int.TryParse(resetPasswordLengthConfig, out resetPasswordLength))                 {                     resetPasswordLength = defaultPasswordLength;                 }             }             base.Initialize(name, config);         }          public override string GeneratePassword()         {             return Utils.PasswordGenerator.GeneratePasswordAsWord(resetPasswordLength);         }     } } 

Here’s my App.Config for my seperate Test Class Library MyCompany.MyApp.Doman.Test.dll that references my business domain library above:

<?xml version='1.0' encoding='utf-8' ?> <configuration>     <connectionStrings>         <add name='SqlServer' connectionString='data source=mycomp\SQL2008;Integrated Security=SSPI;Initial Catalog=myDatabase' providerName='System.Data.SqlClient'/>     </connectionStrings>     <system.web>         <membership defaultProvider='MyMembershipProvider' userIsOnlineTimeWindow='15'>             <providers>                 <clear/>                 <add name='MyMembershipProvider'                      type='MyCompany.MyApp.Domain.MyMembershipProvider,MyCompany.MyApp.Domain'                      connectionStringName='SqlServer'                      applicationName='MyApp'                      minRequiredNonalphanumericCharacters='0'                      enablePasswordRetrieval='false'                      enablePasswordReset='true'                      requiresQuestionAndAnswer='false'                      requiresUniqueEmail='true'                      passwordFormat='Hashed'/>             </providers>         </membership>     </system.web> </configuration> 

Here’s my method that throws ‘Object reference is not set to an instanve of an object’

public class MemberTest     {         public static void CreateAdminMemberIfNotExists()         {             MembershipCreateStatus status;             status = MembershipCreateStatus.ProviderError;              MyMembershipProvider provider = new MyMembershipProvider();              provider.CreateUser('Admin', 'password', '[e-mail]', 'Question', 'Answer', true, Guid.NewGuid(), out status);         }     } 

it throws on the provider.CreateUser line

I’m quite sure you should call provider.Initialize(…) in your test code before calling CreateUser.
