ftp - Invalid Uri: invalid port specified C# -


i created ftp server locally filezilla server. admin port 14147 default. filezilla client got connected no problems.

when try connect chrome or ie 

ftp://(ip)

or 

ftp://(full machine name)

or 

ftp://(user:password)@(machine).

everything ok.

my admin interface setting port 14147. listing port default 21

no problems @ internet browsers telnet.

now created application in c# , when use uri class

uri target = new uri(struri);

i got exception error: invalid uri: invalid port specified

i saved ftp address in database , tried many variations nothing happens:

ftp://user:password@fullmachinenamewithdomain ftp://user:password@fullmachinenamewithdomain:21 ftp://user:password@fullmachinenamewithdomain:14147

what doing wrong?

afaik username , password not supposed part of url. should pass them separately credentials when you're using ftpwebrequest class. e.g.

request.credentials = new networkcredential(username, password);

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
