C#, is there 'Defer Call' like golang?

Question

golang support 'Defer Call' and when c++, I use this trick(?).

struct DeferCall
{
   DeferCall() {}
   ~DeferCall() { doSomeThing(); }
}

void SomeMethod()
{
    DeferCall deferCall;
    ...
}

how can I do this in c# ?

I need like this golang defer tutorial

Answer 1

The nearest language equivalent will be try-finally:

try
{
    DoSomething();
}
finally
{
    DoCleanup();
}

The nearest framework equivalent will be IDisposable + using:

using (var stream = File.OpenRead("foo.txt"))
{
    // do something
}

Personally, defer term confuses me, since this is not "deferred execution" (schedule now - execute later, which could be implemented via tasks), but some sort of RAII implementation.

P.S. Assuming, that you will continue to learn golang:

• panic equivalent is throw
• recover equivalent is catch
