Shortest way to check for null and assign another value if not

Question

I am pulling varchar values out of a DB and want to set the string I am assigning them to as \"\" if they are null. I\'m currently doi

Answer 1

To assign a non-empty variable without repeating the actual variable name (and without assigning anything if variable is null!), you can use a little helper method with a Action parameter:

public static void CallIfNonEmpty(string value, Action action)
{
    if (!string.IsNullOrEmpty(value))
        action(value);
}

And then just use it:

CallIfNonEmpty(this.approved_by, (s) => planRec.approved_by = s);
