Hello,
Am using .net c#

I have a .net page that calls a class as thus:

user_processor myclass = new user_processor();

And the class does some work and is "MEANT" To give a feedback to the calling page. Which i tried using. ( Here is my edited code )


public class user_processor
{
	public  user_processor(string user)
    {

try
            {
                int lenght = Int32.Parse(csv[0]);

                statusquo = "success";
                { return statusquo; }
            }
            catch
            { 
                 //IF ERROR
                 statusquo = "failure";
                {return statusquo ;}
            }

I get the error

Compilation Error

Your declaration:


public  user_processor(string user)

Doesn't indicate the return type of your method. If it is returning a string, you should write:


public string user_processor(string user)

Also note that it is bad practice to return strings like "success" or "failure"; you should either return a boolean value or an enum.

Thanks Jeff,
As i said, I actually edited my code above. My return value initially was an integer.

Adding string. I now get this error.

Line 18: public string user_processor(string user

The error is telling you exact what the problem is. Member names cannot be the same as their enclosing type. You have pick a different name for your method.

Ok.
I picked a different name but still got an error

not all code paths return a value

Then I added an output parameter as thus

Line 18: public string user_processor(string user, out int Ehi )

Then later in the code assigned the output parameter to replace the statusquo. But still get the error

not all code paths return a value

post the class as it is. that's the best way for us to find the error.

ctors cannot have a return type. that method you posted is not a method, but a ctor.

generally ctors should not do any work. they should just initialize the class with default values or values that you pass in if it's not a default ctor.

add a method returning string or whatever that is named something different from the name of your class (user_processor) to do the actual work.

hi Guys,
i finally got it to work.

Mladen, I actually hadnt got a "FULL CODE" as i was testing a new class.

I used a private constructor, as thus...


 private static string mytest = "somevalue";
    public static string testing
    {
        get
        {
            return mytest;
        }
        set
        {
            mytest = value;
        }
    }

that's not a private constructor. that's a private field named "mytest", with public property named "testing"
