In your code its seems to be Only the Try block returns the value and not the Catch Block thats the cause of the error. Try like this public string test() { try { return  ; } catch { return  ; } }

just use Response.Redirect(mail.aspx);

Hi Try this. try { if(somecondition) { return something; //optional } else { return something; // optional } } catch(Exception) { } return something; //else error will raise. the first two return statements are not considering in this case. because of its inside the if block.

Can you fix it what error is occuring. I mean you are saying in post that Not all code path returns value it is one of the compile time error but in your attachment you are showing error which generally occurs runtime.

Unfortunately your code has come out as a muddle when you pasted it in and is therefore difficult to follow. However it looks to me as though there is no return statement in the 'if' block but there is a return statement in the 'else' block. Correcting the error may therefore be as simple as placing the line: return companymailid; at the end of the 'if' block.
