c# - Filter users by attribute -

-

this gives list of userprincipals our activedirectory users in group "x":

var domaincontext = new principalcontext(contexttype.domain); var groupprincipal = groupprincipal.findbyidentity(domaincontext, identitytype.samaccountname, "x");

now how filter users in list custom attribute? users have entry in custom property "building", , want list contain users building.

solution

stupid me ... cast members groupprincipal directoryentry, access properties ..

        foreach (var member in groupprincipal.members)         {             // maybe try-catch ..             system.directoryservices.directoryentry = (system.directoryservices.directoryentry)member.getunderlyingobject();             if (i.properties["building"].value.tostring() == "nsa hq")             {                 // stuff here             }          }

yes, may use member.getunderlyingobject()

var members = groupprincipal.members.where(member=>(member.getunderlyingobject() directoryentry).properties["building"].value.tostring() == "nsa hq");

as pointed out in retrieve ad custom attribute in 1 batch

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...
