Select Data from Datable with condition

Question

I have data in datatable Like below .

............................

Link        |      Value

............................

 E1    |Monitorlog  

 E2    | Dashboard

 E3    |Tester

 
now i want to assign value in a String on runtime

Like 

String E1  = Monitorlog when link = =  E1

please suggest me different approach.Is  any  other.  
I have already implemented like below 

if (configTable.Rows[i]["Link"].ToString().ToUpper() == "MONITORLOG")
 _urlMonitor = configTable.Rows[i]["Value"].ToString();
