Hiee guys,
I have several image urls from which i download the data and save it in db. I use (imageurl.Split('/'))[(imageurl.Split('/').Length) - 1]; to create the filename.
Problem is,there are some urls which contains query string. due to which filenames i get for them have pattern imgname.img_type_extension?somefield=somevalue
How can i get filename.extension leaving query string from above substring??
Thanks for stopping by...
var path = imageurl.Split('?')[0]; var fileName = Path.GetFileNameWithoutExtension(path); EDIT : for file name WITH extension just use another method from Path
var path = imageurl.Split('?')[0]; var fileName = Path.GetFileName(path); 
Why not let the UriBuilder do the parsing for you?
var url = new UriBuilder("http://x.com/xyz/imgname.img_type_extension?somefield=somevalue"); string filename = Path.GetFileName(url.Path); 
Uri do the parsing? My guess is newing up a simple, immutable Uri type would be more performant, but maybe not...?How about
var fNameWithQuery = (imageurl.Split('/'))[(imageurl.Split('/').Length) - 1]; //get first string from array created by splitting substring on occurence of '?' var fNameAndExt = fNameWithQuery.Split('?')[0]; Perhaps this?
string imgUrl = @"C:\blah.jpg"; //Loaded from DB System.IO.FileInfo f = new System.IO.FileInfo(imgUrl); string fileName = f.Name.Split('.')[0];
