I need a slow C# function

Question

For some testing I\'m doing I need a C# function that takes around 10 seconds to execute. It will be called from an ASPX page, but I need the function to eat up CPU time on

Answer 1

You can use a 'while' loop to make the CPU busy.

    void CpuIntensive()
    {
        var startDt = DateTime.Now;

        while (true)
        {
            if ((DateTime.Now - startDt).TotalSeconds >= 10)
                break;
        }
    }

This method will stay in the while loop for 10 seconds. Also, if you run this method in multiple threads, you can make all CPU cores busy.
