Attach StackTrace To Exception Without Throwing in C# / .NET

Just create your own Exception type and override the StackTrace property:

class MyException : Exception
{
    private string oldStackTrace;

    public MyException(string message, string stackTrace) : base(message)
    {
        this.oldStackTrace = stackTrace;
    }


    public override string StackTrace
    {
        get
        {
            return this.oldStackTrace;
        }
    }
}
