How to convert TArray<'FString> to char **?

TCHAR_TO_ANSI can’t be used to store variable, check the doc on that macro.

I find a solution :

const char ** achar = new const char*outArray.Num();

int32 i = 0;

while (i < outArray.Num()) {
achar[i] = (char*)outArray[i].GetCharArray().GetData();
i++;
}
