Your Question is not clear.
but take a look here it may help full for you.
I had also face situation similar to this.
In my case "the error is an ambiguous reference between
System.Windows.Forms.Label and
ZedGraph.Label"
actually both of these name spaces having same class name Label
when i create a variable of Label then system confuses what is meant by Label is it form ZedGraph or System.Windows.Forms.
i solve this problem by this.
using System.Windows.Forms;
using ZedGraph;
using zedLabel = ZedGraph.Label;
using Label = System.Windows.Forms.Label;
when i want to create a object of type ZedGraph.Label then i use
ZedGraphLabel Objec = new ZedGraphLabel()
if i create an object like this.
Label l = new Label();
and an other way is this use complete reference . like this
Zedgraph.Label objLabel = new Zedgraph.Label();
System.Windows.Forms.Label objLabel2 = new System.Windows.Forms.Label();
I hope you understand..
