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
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 zedLabel = ZedGraph.Label;
using Label = System.Windows.Forms.Label; // here i am explicitly telling what i mean of Label so the System do not confuse with Other Object having same name in other namespace
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.
// it creates a label of type System.Windows.Forms.Label;
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..
