Problem with Typecast in Generic class "Cannot convert type 'string' to 'T' "

[niharnayak2003]

Hi All,
I am facing the problem in Typecast inside the Generic class.
I need a function which will take two param 1:-Xpath 2:- XMLDOC
and return me what i will need.

here is the code for accessing to the Generic class.

private double mtrxgraphdata;
private XMLdocument Matrixdata;
 
GraphControl.XMLUtility<double> obj = new XMLUtility<double>();
 mtrxgraphdata = obj.GetElement("//Matrix/matrixdata/",Matrixdata);
 
 
 
Here is the code for the Generic class.
class XMLUtility<T>
          {
            public T GetElement(string Xpath,XmlDocument XmlDoc)
            {
 
                XmlNodeList Elements = XmlDoc.SelectNodes(Xpath);
                T[] returnList = new T[Elements.Count];
                    int counter = 0;
                    foreach (XmlNode node in Elements)
                    {
                        returnList[counter] =(T) node.InnerText;// here i am getting  error  "Cannot convert type 'string' to 'T' "
                        counter++;
                    }
                }
                return returnList;
 
            }
         }

Thanks in advance
