"HLLW.ClassBase.blnConnectAccess (string)": Not all code paths return a value

lemontfly

How do I resolve this error?
I want to customize a method in the newly created cs file, as follows:
bool blnConnectAccess (string strAccountPath)
        {
            if (strAccountPath! = "")
            {
                if (System.IO.File.Exists (strAccountPath))
                {

                }
                else
                {
                    
                }
            }
        }

The result is that prompt, somehow why? How to solve it?

All exits of the function should be written with the return value

TO: if (strAccountPath! = "")
            {
             }

The reason for your error is here:

strAccountPath! = "" You processed it, what if strAccountPath == ""? No return value ...

Add else return ..;

Or directly return ..

Not all code paths return a value
This shows that there may be no return value in your branch, and your return value is not void, you have to return something to him. From your code above, there is nothing

It ’s a good explanation, I know it at a glance, thanks!
