How to calculate MOSFET gate resistor value? 

Thank you for including the Cgs capacitance! This is a helpful step for designing a resonant mode configuration for the MOSFET.

Thanks for this. I noticed that Ton time you used is 1ns, the data sheet does not state 1ns, please how did you get that?

Thanks knowledgeable for me Thanks.Thanks

You need rg to avoid short circuit. Rl is similar.

Why not Qg but 2*Qg，Qg should be the charge of the object driving voltage instead of using the maximum Qg
