wish helps you I will say that your second example is more than adequate solution to your problem.
Unlike other answers, it actually makes it explicit that you only want values that can be parsed. All other solutions, while being clever, obfuscate this fact. The main reason why I found the second example a better solution is isParsed field, especially when coupled with .Where(x => x.isParsed). This is what makes it obvious that you want only values that were successfully parsed. Anyone who reads the code for the first time will immediately think "only get values that were parsed". Also, there is no ambiguity in the code.

hop of those help? I'm trying to make my own understandable example of what the method RelayCommand is doing in the following code: , Well, you could do:
code :
static void Main(string[] args)
    int[] numbers = { 6, 3, 7, 4, 8 };

    Console.WriteLine("The addition result is {0}.",
        Tools.ProcessNumbers(p => Tools.AddNumbers(p), numbers));

    Console.WriteLine("The multiplication result is {0}.",
        Tools.ProcessNumbers(p => Tools.MultiplyNumbers(p), numbers));

This might help you When you want users to use be able to use a lambda syntax all you have to do is take a parameter which is an interface with exactly one abstract function.
The callers decide to use a method reference, a lambda with the
code :
class EnumRadioButtons<T> {

    public EnumRadioButtons(Collection<T> options, Function<T,String> f ) {
        for (T option : options) {
            this.setTitleOfEachOption(option, f.apply(option));

    public void setTitleOfEachOption(T option, String title) {
          System.out.println("DEBUG - Setting title of option: " + option  + " to have title of: " + title );
enum MyEnum {

    public String myToString() {
        return toString();
class User {
    public static void main(String[] args) {

        EnumRadioButtons<MyEnum> bts 
                = new EnumRadioButtons<>(Arrays.asList(MyEnum.values()),
                        MyEnum::myToString); // user of method reference

around this issue [] is a shortcut, and it may not be designed to accept blocks.
Either use a traditional method (which in this case is only 1 char longer):
What is the required syntax to pass a block to a pure C function?

should help you out The question has caused some confusion, because blocks (in the question's sense) are not a feature of standard C. Apple added them as an extension to its C and C++ compilers when it added them to Objective C, but they are not a C thing outside the Apple ecosystem. I confess that I've no experience actually using them, but as far as I can tell from the docs, such as these, the syntax was chosen so as to be the same for C, C++, and Objective C. Indeed, some sources claim that details of the syntax were chosen specifically to avoid the possibility of conflict with C++.
From a C perspective, accepting a block as a parameter and calling a block received that way are thoroughly analogous to accepting a function pointer and calling the pointed-to function, respectively. Your example C function appears to be correct.
code :
   void (^myBlock1)(void) ;
int myInt = 1;

myInt;  // specifically, analogous to this
    double someNumber;
    someNumber= pureCfunctionWithABlockParameter(0, 1, myBlock1 );
void (^block)(int)
void pass_2(void (^do_something)(int)) {
