VB.NET Optional parameters - bound in caller or callee? -


if setup optional parameters on method in vb.net class, optional parameters supplied caller or called method?

in c++, supplied called method. in c#, supplied caller method.

wondering how worked in vb.net.

caller.

another caveat c# folks might not know c# version of optional parameters suffers same limitations of vb version (which, way, has been in vb since vs 2002). namely, optional parameter value compiler trick, optional parameter value not compiled method called, instead caller.

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!
