❔ Custom "block" statement such as while..do

Hello, is it possible to build a custom block? For example

// usage
DoRequestAsync
{
    Categories = await _stockBrowser.GetCategoriesAsync();
}

// code behind DoRequest
private async Task DoRequestAsync()
{
    try
    {
        // children
    }
    catch (Exception e)
    {
        Console.WriteLine(e);
        Error = true;
    }
}

// usage
DoRequestAsync
{
    Categories = await _stockBrowser.GetCategoriesAsync();
}

// code behind DoRequest
private async Task DoRequestAsync()
{
    try
    {
        // children
    }
    catch (Exception e)
    {
        Console.WriteLine(e);
        Error = true;
    }
}

I have a lot of requests that requires a try catch block.

no, C# doesn't have a way to add new syntax

What would be the best way to solve the try catch disaster? Use a try catch around each request?

Aaron•2y ago

that highly depends on how the rest of your code is structured

I mean you could sorta emulate it

await DoRequestAsync(async () =>
{
    Categories = await _stockBrowser.GetCategoriesAsync();
}):

await DoRequestAsync(async () =>
{
    Categories = await _stockBrowser.GetCategoriesAsync();
}):

The usual way of handling that is to have a global exception handler and let the exceptions bubble up

you can always use ANTLR 😆

Use Polly, it's ultimate library for this kind of things.

Was this issue resolved? If so, run /close - otherwise I will mark this as stale and this post will be archived until there is new activity.
