Protected Sub New (info As SerializationInfo, context As StreamingContext)

Parameters

Examples

The following code example shows an implementation of the MembershipCreateUserException class that calls the protected constructor of the base class with the supplied serialization information and context.

using System.Web.Security;
using System.Runtime.Serialization;

public sealed class MyCreateUserException : MembershipCreateUserException
{
  public MyCreateUserException(SerializationInfo info, StreamingContext context) : base(info, context)
  {
  }
}

Imports System.Web.Security
Imports System.Runtime.Serialization

Public NotInheritable Class MyCreateUserException
  Inherits MembershipCreateUserException

  Public Sub New (info As SerializationInfo, context As StreamingContext)
    MyBase.New(info, context)
  End Sub
End Class

Remarks

This constructor is called during deserialization to reconstitute the exception object transmitted over a stream. For more information, see XML and SOAP Serialization.

public MembershipCreateUserException(string message, Exception innerException);

new System.Web.Security.MembershipCreateUserException : string * Exception -> System.Web.Security.MembershipCreateUserException

Public Sub New (message As String, innerException As Exception)

Parameters

Examples

The following code example calls the CreateUser method to create a new membership user. If the user creation fails, a MembershipCreateUserException is thrown. If the exception is not a MembershipCreateUserException, the caught exception is supplied as the InnerException of the MembershipCreateUserException that is thrown.

public MembershipUser MyCreateUser(string username, string password, string email)
{
  MembershipUser u = null;

  try
  {
    u = Membership.CreateUser(username, password, email);
  }
  catch (MembershipCreateUserException e)
  {  
    throw e;
  }
  catch (Exception e)
  {  
    throw new MembershipCreateUserException("An exception occurred creating the user.", e);
  }

  return u;
}

Public Function MyCreateUser(username As String, password As String, email As String) As MembershipUser

  Dim u As MembershipUser = Nothing

  Try
    u = Membership.CreateUser(username, password, email)
  Catch e As MembershipCreateUserException
    Throw e
  Catch e As Exception  
    Throw New MembershipCreateUserException("An exception occurred creating the user.", e)
  End Try

  Return u
End Function

Remarks

An instance of the MembershipCreateUserException class is thrown by the Membership.CreateUser method when the user is not created.

You can use this overload of the MembershipCreateUserException constructor to supply information regarding a caught exception that occurred while the user was being created.
