Description Prashant Cholachagudda 2014-06-12 11:56:35 UTC
Calling ToString on an integer throws an System.AggregateException when used within Parallel.For


- Set the device locale to French (fr)
- Add the below code in main activity's `OnCreate` method
  `Parallel.For(0, 5000, i => variable.ToString("0.0", CultureInfo.CurrentCulture));`
- Run the project
Comment 1 Ram Chandra 2014-06-12 12:45:24 UTC
I tried this issue and with the help of bug description I am able to reproduce this issue.

Steps to reproduce:

1. Create an "Android Application" on XS.
2. Paste the following code on "OnCreate" method of "MainActivity.cs" file

            var currentCulture = CultureInfo.CurrentCulture;
            var variable = 10;
            Parallel.For(0, 5000, i => variable.ToString("0.0",currentCulture));

3. Deploy the application.
4. Exception will occur.

I observed that when I write the following code I am also getting "System.AggregateException" on my current culture i.e "en-IN"
            var currentCulture = CultureInfo.CurrentCulture;
            var variable = 10;
            Parallel.For(0, 5000, i => variable.ToString("0.0",currentCulture));

I also observed that when I convert int variable to string outside the "Parallel.For()" I am not getting "System.AggregateException".
