Hello,
I'm trying to request all accounts from CRM with SDK.
But I got a null reference object at line RetrieveMultiple. Here's my code:
Dim service As IOrganizationService = _serviceProxy
Dim page = New PagingInfo()
page.Count = 5000
page.PageNumber = 1
Dim filter = New FilterExpression()
filter.AddCondition("yominame", ConditionOperator.Contains, "a")
Dim queryAccount As New QueryExpression With { _
.EntityName = Account.EntityLogicalName,
.ColumnSet = New ColumnSet(True),
.PageInfo = page,
.Criteria = filter
}
Dim retrieve = New RetrieveMultipleRequest()
retrieve.Query = queryAccount
Dim accounts = New RetrieveMultipleResponse()
accounts = CType(service.Execute(retrieve), RetrieveMultipleResponse)
Connection to CRM is ok, I can retrieve Firstname and Lastname of SystemUser.
I tried without Criteria ... but same error:
System.NullReferenceException was unhandled
Message=La référence d'objet n'est pas définie à une instance d'un objet.
