The following code reproduce an error that I have encountered using lambda functions.

In this post(Why member functions can’t be used as template arguments?) I have seen that you can use pointers to member functions as template parameters, for example:

Is there a way to define a lambda’s capture clause conditionally?

I am running gcc 11.4.0 under PopOS 22.04 LTS. I am attempting to create a “conditional callback” with a lambda using references and pointers, like this:

How long is a parameter (captured by value) within a lambda expression valid?
Is the parameter valid for the lifetime of the lambda itself, or is it only valid only for the duration of the call?

If I have a class which contains std::function and I’d like to pass a lambda which is temporary on the stack, will it cause issues once that portion of the stack is destroyed/overwritten?

So I reverse engineered a DLL using dotpeek from jetbrains and it wrote code that was too modern. I was left with lambda => expressions which visual studio 2010 doesn’t understand. The goal of all of this is to replace a dll with editable source code.

public bool SomeCondition(string someString) => _someService.Compare(someString).Constant.Constant1 == Constant.Constant2; public bool SomeCondition(string someString) => _someService.Compare(someString).Constant.Constant1 == Constant.Constant2; Which of these is the agreed approach in C#? c# lambda New contributor user24952889 is a new contributor to this site.
