MSCRM，檢索實體表單列表

Question

我需要一個給定實體（multiform）的所有表單的列表;我知道客戶端Javascript代碼的解決方案，但我使用服務器端代碼。

我嘗試使用此消息得到實體的元數據，但我不能找到它：

RetrieveEntityRequest mdRequest = new RetrieveEntityRequest() 
    { 
     EntityFilters = EntityFilters.All, 
     LogicalName = entityName, 
     RetrieveAsIfPublished = false 
    }; 

我試着檢索實體FormXML，但它不存在或者：

private string GetFormXML(int objectTypeCode) 
{ 
     QueryExpression q = new QueryExpression("systemform"); 
     q.ColumnSet = new ColumnSet("formxml"); 
     q.Criteria.AddCondition(new ConditionExpression("type", ConditionOperator.Equal, 2)); 
     q.Criteria.AddCondition(new ConditionExpression("objecttypecode", ConditionOperator.Equal, objectTypeCode)); 

     var entities = ctx.OrganizationService.RetrieveMultiple(q); 

     if (entities != null) 
     { 
      return entities.Entities.First().Attributes["formxml"].ToString(); 
     } 
     else 
     { 
      return ""; 
     } 
} 

任何建議？

Answer 1

我認爲systemform實體具有objecttypecode作爲字符串，它接受實體名稱而不是真正的實體對象類型代碼。你可以嘗試改變對象類型代碼從數字到實體名稱？

private string GetFormXML(int objectTypeCode) 
{ 
     QueryExpression q = new QueryExpression("systemform"); 
     q.ColumnSet = new ColumnSet("formxml"); 
     q.Criteria.AddCondition(new ConditionExpression("type", ConditionOperator.Equal, 2)); 
     q.Criteria.AddCondition(new ConditionExpression("objecttypecode", ConditionOperator.Equal, "contact")); 

     var entities = ctx.OrganizationService.RetrieveMultiple(q); 

     if (entities != null) 
     { 
      return entities.Entities.First().Attributes["formxml"].ToString(); 
     } 
     else 
     { 
      return ""; 
     } 
}

 public Dictionary<Guid, string> GetNevegationItems(int objectTypeCode) 
    { 
     QueryExpression q = new QueryExpression("systemform"); 
     q.ColumnSet = new ColumnSet("name", "formid"); 
     q.Criteria.AddCondition(new ConditionExpression("type", ConditionOperator.Equal, 2)); 
     q.Criteria.AddCondition(new ConditionExpression("objecttypecode", ConditionOperator.Equal, objectTypeCode)); 

     var entities = ctx.OrganizationService.RetrieveMultiple(q); 

     if (entities != null) 
     { 
      Dictionary<Guid, string> rslt = new Dictionary<Guid, string>(); 
      foreach (var item in entities.Entities) 
      { 
       rslt.Add(item.GetAttributeValue<Guid>("formid"), item.GetAttributeValue<string>("name")); 
      } 
      return rslt; 
     } 
     else 
     { 
      return null; 
     } 
    }
