检索CRM 4个实体与自定义工作流活动的C＃自定义字段

Question

我试图检索与机会，这statecode不等于1试过QueryByAttribute，QueryExpression和RetrieveMultipleRequest，但仍没有解决方案的所有电话。
这里是一些代码，我写的。

 IContextService contextService = (IContextService)executionContext.GetService(typeof(IContextService)); 
     IWorkflowContext context = contextService.Context; 
     ICrmService crmService = context.CreateCrmService(true); 
     if (crmService != null) 
     { 
      QueryByAttribute query = new Microsoft.Crm.Sdk.Query.QueryByAttribute(); 
      query.ColumnSet = new Microsoft.Crm.Sdk.Query.AllColumns(); 
      query.EntityName = EntityName.phonecall.ToString(); 
      query.Attributes = new string[] { "regardingobjectid" }; 
      query.Values = new string[] { context.PrimaryEntityId.ToString() }; 
      RetrieveMultipleRequest retrieve = new RetrieveMultipleRequest(); 
      retrieve.Query = query; 
      retrieve.ReturnDynamicEntities = true; 
      RetrieveMultipleResponse retrieved = (RetrieveMultipleResponse)crmService.Execute(retrieve); 
     } 
     return ActivityExecutionStatus.Closed; 
    } 

而对于QueryExpression

QueryExpression phCallsQuery = new QueryExpression(); 
ColumnSet cols = new ColumnSet(new string[] { "activityid", "regardingobjectid" }); 
phCallsQuery.EntityName = EntityName.phonecall.ToString(); 
phCallsQuery.ColumnSet = cols; 
phCallsQuery.Criteria = new FilterExpression(); 
phCallsQuery.Criteria.FilterOperator = LogicalOperator.And; 
phCallsQuery.Criteria.AddCondition("statuscode", ConditionOperator.NotEqual, "1"); 
phCallsQuery.Criteria.AddCondition("regardingobjectid", ConditionOperator.Equal, context.PrimaryEntityId.ToString(); 

几乎相同，我总是得到这样的SOAP异常或“服务器无法继续请求”调试时。

为了得到异常的详细尝试使用下面的代码：

RetrieveMultipleResponse检索= NULL;

try 
{ 
    retrieved = (RetrieveMultipleResponse)crmService.Execute(retrieve); 
} 
catch(SoapException se) 
{ 
    throw new Exception(se.Detail.InnerXml); 
}
