c# - How to extend TextAreaFor in MVC -

-

i know how extend textboxfor :

public static mvchtmlstring textboxfor<tmodel, tvalue>(this htmlhelper<tmodel> htmlhelper, expression<func<tmodel, tvalue>> expression, object htmlattributes)         {             mvchtmlstring html = default(mvchtmlstring);             routevaluedictionary routevalues = new routevaluedictionary(htmlattributes);                      html = system.web.mvc.html.inputextensions.textboxfor(htmlhelper, expression, routevalues);             return html;         }

i want same textareafor unfortunately system.web.mvc.html.inputextensions dose not contain textareafor method. how can solve ?

see doc, it's in textareaextensions static class

return system.web.mvc.html.textareaextensions.textareafor(htmlhelper, expression, routevalues);

or just

return htmlhelper.textareafor(expression, routevalues);

by way, third argument (as in textboxfor) idictionary<string, object> htmlattributes, nothing routevalues.

it's working because routevaluedictionary implements idictionary<string, object>, arguments confusing.

i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
