c# - Random.Next() 的异常使 try-catch block 中的程序崩溃

Question

所以，这发生了:

在 try block 中这怎么可能？为什么它不将其转发给 catch block ？

编辑:

有人指出，我可能有递归。我知道，我认为这不会造成问题。

完整的方法如下所示:

private static GeoCoordinate ChangeLocation(GeoCoordinate location)
{
    var tmp = location;
    var direction = new Random().Next(0, 359);
    var distance = new Random().Next(0, 5);

    //Calculate movement
    var vertical = Math.Sin(direction) * distance; //Sinus relation shortened
    var lastAngle = 180 - 90 - (direction % 90);
    var horisontal = Math.Sin(lastAngle) * distance; //Sinus relation shortened

    //Add movement to location
    tmp.Latitude = location.Latitude + (vertical / 10000);
    tmp.Longitude = location.Longitude + (horisontal / 10000);

    //If new location is outside a specific area
    if (!InsidePolygon(_siteCoordinates, tmp))
    {
        _recursiveCounter++;
        //Ninja edit: @Leppie pointed out I was missing 'tmp =':
        tmp = ChangeLocation(location); //Recursive move to calculate a new location
    }

    //Print the amount of recursive moves
    if (_recursiveCounter != 0)
        Console.WriteLine($"Counter: {_recursiveCounter}");
    _recursiveCounter = 0;

    return tmp;
}

Starting with 2.0 a StackOverflow Exception can only be caught in the following circumstances.

1. The CLR is being run in a hosted environment where the host specifically allows for StackOverflow exceptions to be handled
2. The stackoverflow exception is thrown by user code and not due to an actual stack overflow situation (Reference)
