FFT development in .net required for generation of harmonics in the system. Can you provide suggestions in this regard?

The parameters file is:

3.3 FFT
The FFT is always performed on the data in file ‘TestData.bin.txt’. FFT direction can be
forward or inverse and 1D and 2D FFTs are supported.
Two files are generated:
• TestData.fft.bin.txt
• TestData.fft.float.txt
3.3.1 1D FFT
Input parameters include direction (inverse or forward), FFT length (between 64 and 1M
point and power of 2), and number of FFTs (loops). For a 1D FFT, number of FFTs *
FFT length must not exceed 1M (= 1K x 1K).
3.3.2 2D FFT
Input parameters include direction (inverse or forward), FFT side length (between 64 and
1024 point and power of 2), and number of FFTs (loops). For a 2D FFT, number of FFTs
* side length * side length must not exceed 1M (= 1K x 1K).
if you need more explanation on fft you can use the key search (fft + muzhir), beacuse i published many papers on this work
