Hello ppl,

Chapter 5, User and Authentication, page 173, method Update:

public bool Update()
{
Configuration.ModuleSettings moduleSettings = Configuration.ModuleConfig.GetSettings();

Data.Role dataRole = new Data.Role(moduleSettings.ConnectionString);

return roleId = dataRole.Update(roleId, description);
}


This method causes 2 erros:

error CS0029: Cannot implicitly convert type 'bool' to 'int'
error CS0029: Cannot implicitly convert type 'int' to 'bool'

I understand implicit conversions, but I don't understand why this error doesn't come up in my downloaded code? What does it convert in theirs and not in mine?

Hi Kim

It seems you have written this version of the code yourself.
Doing so you have made a mistake in the last line of the code.
the last line of your looks like this

return roleId = dataRole.Update(roleId, description);

the problem here is that you are assigning the return value
of "dataRole.Update" function which is of type bool to "roleId"
which is an int type variable.

This step is not needed so you can simply do away with the assignment
part so that the code looks only like this

return dataRole.Update(roleId, description);

and the entire function looks like this


        public bool Update()
        {
            Configuration.ModuleSettings moduleSettings = Configuration.ModuleConfig.GetSettings();
            Data.Role dataRole = new Data.Role( moduleSettings.ConnectionString );

            return dataRole.Update(roleId, description);
        }

this should resolve the problem.

Write back if there is anything else you wanna ask.
