FuncExtensionsMemoizeT, TResult Method (FuncT, TResult)

Returns a memoized version of a referentially transparent function. The memoized version of the function keeps a cache of the mapping from arguments to results and, when calls with the same arguments are repeated often, has higher performance at the expense of higher memory use.

A limitless cache is used.

Copy
Func<int, int> inc = x => x + 1;
