SafeInvoke<TResult>(Func<TResult>, Func<TResult, TResult>, Action<Exception>)

Provides a generic way to abide the rule description of CA2000 (Dispose objects before losing scope).

public static TResult SafeInvoke<TResult>(Func<TResult> initializer, Func<TResult, TResult> tester, Action<Exception> catcher = null) where TResult : class, IDisposable

Parameters

initializer Func<TResult>

The function delegate that initializes an object implementing the IDisposable interface.

tester Func<TResult, TResult>

The function delegate that is used to ensure that operations performed on TResult abides CA2000.

catcher Action<Exception>

Returns

TResult

The return value of the function delegate initializer if the operations succeeded; otherwise null if the operation failed.

Type Parameters
