c# - Using a pre-existing PHP script to upload images to a server -

-

i'm creating winform application need upload image files central image server. before this, there pre-existing php script has been written allow images uploaded server via web portal. i've been told can make program access php script , use functionality.

how possible?

so far i've tried following lines of code:

iphostentry iphostinfo = system.net.dns.gethostentry("http://scriptlocation.html"); ipaddress ipaddress = iphostinfo.addresslist[0];  using (tcpclient client = new tcpclient()) {    client.connect(ipaddress, 21);    client.sendtimeout = 3000;    var status = client.connected;    lblstatus.text = status.tostring();    console.writeline(status); }

but when run following error;

no such host known

i'm new network programming this, please point me in right direction?

if understand correctly trying send file http.

consider using webclient:

using(var wc = new webclient()) {     wc.uploaddata("http://scriptlocation.html", "post", data); }

where data file byte array;

(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...
