连接角色不相关

Question

XrmServiceContext  xrmSvc  = null; 
xrmSvc = new XrmServiceContext("http://mycrmwebdev/CRMDev") 
Connection cnctn = xrmSvc.ConnectionSet.Where(c => c.ConnectionId == "3D2BC21F-6D8F-E211-9F0F-1CC1DE248972").First(); 

if (cnctn != null) { 
    CrmEntityReference rec1RoleId = new CrmEntityReference { 
     LogicalName = ConnectionRole.EntityLogicalName, 
     Name = "Record1RoleId", 
     Id = new Guid("B818399C-E766-E111-A1B1-00155D0A6B13") 
    }; 

    CrmEntityReference rec2RoleId = new CrmEntityReference { 
     LogicalName = ConnectionRole.EntityLogicalName, 
     Name = "Record2RoleId", 
     Id = new Guid("B818399C-E766-E111-A1B1-00155D0A6B13") 
    }; 

    cnctn.Record1RoleId = rec1RoleId; 
    cnctn.Record2RoleId = rec2RoleId; 

    xrmSvc.UpdateObject(cnctn); 

    //Error occurs here 
    xrmSvc.SaveChanges(); 
} 

当我尝试保存时，出现错误“连接角色不相关”。我对这个错误没有看到太多。有任何想法吗？

由于CRM中的Connections表中存在相互关系，因此请确保只更新一条记录。 CRM将处理更新互惠记录。
