Solution 1

This kind of error generally occurs when you are branching out your code (using if-else or switch case) and then returning values from some of the conditions but not all.

This is the compiler error CS0101 and you can read more about it here[^]. They have a sample that should explain the error to you as well.

Yes. abhinav. OP has not return value from function.
good suggestion.5.

Thanks.

Solution 2

Simple. Error suggest you exact problem.
You have a function in which you may have not return any value or return value in if loop.
to resolve it check following things
1. change the function return to VOID (if you does not return something)
2. give return keyword with variable name before end function

5! However, OP needs to add a return statement to cover the method rather than remove it completely.

I have returned the respective value. Yet i am getting that error....

Improve your question using the "Improve question" link. Post the method causing the error.

We're going to see at least one possible code path that does not return a value.

Solution 3

In your method if your method returning a value then, The error shows that there are still some possible ways missing for returning your data from method.

You can give me code portion where you find this kind of error. I will mark possible ways you left.

THE CODE:

private bool isvalidationreq_groupq(DataView Subquestion)
{
try {
int i = 0;
thisSubQuestionserial = 1;
bool retval = false;
for (i = 0; i <= Subquestion.Count - 1; i++) {
if (Convert.ToInt32(Subquestion[i]["Validationcount"]) > 0) {
Validationtext.Add(Subquestion[i]["Question_ID"].ToString(), " for Question-" + thisQuestionserial.ToString() + "." + thisSubQuestionserial.ToString());
retval = true;
}
thisSubQuestionserial += 1;
}
thisSubQuestionserial = 1;
return retval;
}catch (Exception ex) {
Survey2_0.ReusableComponents.MyExceptionLogger.Publish(ex);
}

}

Hint: What do you return after you've handled the exception?

It looks a lot nicer if you use the "Improve question" link and place your code there within those tags: <pre lang="c#">YourCode</pre>.
That way we could look at it with those fancy code word colours we all love.
