How to format lambda expressions and anonymous methods for maximum readibility?

Question

For instance:

Sorter.SortBy ( array, ( a, b ) =>
{
    return a > b;
} );

What's the best way to format them for maximum readibility?

Also think of it for one parameter lambda version, and other cases that might be used commonly.

What are the guidelines?

Answer 1

Sorter.Filter(array, a => a.IsOK);

Sorter.SortBy(array, (a, b) => a > b);

Collection.Apply(array, (a)       => a * a, // i like lining things up
                        (x, y, z) => WhipIt(x, y) / z,
                        (a, b)    => a + b);

Evaluator.Confuse(array, (a, func) =>  // this is a big one, engage curly braces
{
    if(a.Flag) return 0;
    else
    {
        var x = func(a);
        if(x < 0) return -1;
        else return x * 2;
    }
});
