at umbraco.MacroEngines.DynamicBackingItem..ctor(Int32 Id)
at umbraco.MacroEngines.DynamicNode..ctor(Int32 NodeId)
at umbraco.MacroEngines.Library.RazorLibraryCore.NodeById(Int32 Id)
Is there a method that exists to check if the node exists instead of enclosing within a try catch to avoid the exception stopping the render?

public dynamic GetNodeById (int Id)
DynamicNodeList colNodes = ((DynamicNode)Library.NodeById(-1)).Descendants(n => n.Id == Id);
if (colNodes != null &&
colNodes.Items.Count != 0)
return colNodes.Items as dynamic;
I should I read the
