Lambda variable names - to short name, or not to short name? [closed]

Answer 1

Shortening is better if the purpose of the variable is clear. Lambdas call for a functional style of writing, hence you see a lot of chaining in one single line. Its cleaner to see when you keep them short.

Another case is when sometimes you need to declare a dummy variable which has no relevance/meaning in that scope. In such cases I use _ which makes it clear for me. This comes handy especially during method overloading, for eg,

public Foo Do()
{
    return Do(_ => true);
}

public Foo Do(Func pattern)
{
    return SomethingElse(pattern);
}
