Question

Currently i am having following function

  public int GetVariableValue(TaxReturn taxReturnObj, string identityKey)
    {
        int returnTypeOut = 0;
        if (taxReturnObj.Identity.ContainsKey(identityKey))
        {
            int.TryParse(taxReturnObj.Identity[identityKey], out returnTypeOut);
        }
        return returnTypeOut;
    }

To retrieve the value we are using following code,

e.g.

int valPayStatus = GetVariableValue(objTaxretrun, TaxReturnIdentity.aadata_identity_paystatus)

It was working fine untill now as All the Identity Values were Integer,but recently we have added New Identites with String and Boolean types.
So i want to make the above function as Generic…but i don’t know how to go about that,I tried to search on google but couldn’t find anything.

Answer 1

    public T GetVariableValue<T>(TaxReturn taxReturnObj, string identityKey) 
    { 
        if (taxReturnObj.Identity.ContainsKey(identityKey)) 
        { 
            return (T) Convert.ChangeType(taxReturnObj.Identity[identityKey], typeof(T));
        }
        else
        {
           return default(T);
        }
    }
