Question

I am using a class

public partial class CashFlowIndicator:IEnumerable
{
    public static void getCashFlowChartValues(int userid)
    {
            List<KeyValuePair<string, string>> chartValues=new List<KeyValuePair<string,string>>();
            chartValues = cashFlowChart(userid);
    }    

    public static List<KeyValuePair<string, string>> cashFlowChart(int userid)
    {
              //.............................
              //..................................
            List<KeyValuePair<string, string>> cashFlowItems = new List<KeyValuePair<string, string>>();
            cashFlowItems.Add(new KeyValuePair<string, string>(a, b));
            cashFlowItems.Add(new KeyValuePair<string, string>(c, d));
           //.....................    

            return cashFlowItems;
     }    
}

The problem is while calling the function cashFlowChart, the variable “chartValues” is not getting assigned by the value returned…..

is there any solution?

Based on the method name – “getCashFlowChartValues”, and return type – “void”, here is my guess –

you need to move the definition of “chartValues” outside the methods and make it ‘static’ (as shown below) :

public class CashFlowIndicator :IEnumerable
{

    static List<KeyValuePair<string, string>> chartValues;  // has been moved here from getCashFlowChartValues

    public static void getCashFlowChartValues(int userid)
    {
            //List<KeyValuePair<string, string>> chartValues=new List<KeyValuePair<string,string>>();
            chartValues = cashFlowChart(userid);
    }    

    public static List<KeyValuePair<string, string>> cashFlowChart(int userid)
    {
            //.............................
            //..................................
            var cashFlowItems = new List<KeyValuePair<string, string>>();

            cashFlowItems.Add(new KeyValuePair<string, string>(a, b));
            cashFlowItems.Add(new KeyValuePair<string, string>(c, d));
        //.....................    

            return cashFlowItems;
    }    
}
