Question about overloading methods

[andegre]

I realize this is a very basic question, but is it possible to do this:

public void PersistData(DataSet ds)
{
    try
    {
        sqlCommand.ExecuteNonQuery()
    }
    catch (Exception ex)
    {
        throw ex
    }
)

public bool PersistData(DataSet ds)
{
    try
    {
        sqlCommand.ExecuteNonQuery()
    }
    catch (Exception ex)
    {
        return false
    }
    return true
}

The question is, can I overload a method with the same parameters for both, but have 1 be a "void" and the other return a boolean value? I know MessageBox.Show() does something like this but I can't remember how...

TIA

you can overload the parameters, but not the result.

as an aside. a common convention is to named the methods according to what they do. example

public void PersistData(DataSet ds)
{
    sqlCommand.ExecuteNonQuery();
)

public bool [COLOR=blue]Try[/color]PersistData(DataSet ds)
{
    try
    {
        sqlCommand.ExecuteNonQuery();
    }
    catch (Exception ex)
    {
        Log.Exception(ex);
        return false;
    }
    return true;
}

How does the MessageBox.Show() method work then? I know you can just call that and show your message, or you can have it return a DialogResult variable...or is that based on the MessageBoxButtons that you define in the MessageBox.Show() parameter list?

 

[jmeckley]

The signature of MessageBox.Show is

public static DialogResult Show([overloads])
{
   ...
}

MessageBox.Show() always returns a DialogResult? We may not always catch it though . . .
