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

Arguably the simplest such function is this:

public void Slow()
{
    var end = DateTime.Now + TimeSpan.FromSeconds(10);
    while (DateTime.Now < end)
           /* nothing here */ ;
}
