Question

If I have a method that returns something, like

public DataTable ReturnSomething() {    try    {         //logic here      return ds.Tables[0];    }    catch (Exception e)    {       ErrorString=e.Message;    } } 

This produces compiler error, obviously because catch{} block does not return anything.

So when I have methods with return values I don’t use try-catch block, which is a bad practice. If there is an error, I would like to set error string to that error. But then I need a return value as well. Advice?

Store your return value in a temporary variable like this:

public DataTable ReturnSomething() {     DataTable returnValue = null;      try     {         //logic here         returnValue = ds.Tables[0];      }     catch (Exception e)     {         ErrorString=e.Message;     }      return returnValue; }
