what want though full path of image file. how that? if uploaded desktop "/users/bob/desktop/picture.png"

thanks!

you can't fullpath of file via input type 'file'. browser not allow it. security feature in modern browsers.

in chrome u get

c:\fakepath\filename.ext

while in mozilla u filename

filename.ext

you can find lots of other question related this. see

how full path of file file input

full path file input using jquery

i have following code, , need random item contains string "region_1" dictionary. public static dictionary<int, tuple<string, int, currencytype>> itemarray = new dictionary<int, tuple<string, int, currencytype>>() { { 0xb3e, new tuple<string, int, currencytype>("region_1", 1500, currencytype.fame) } }; public static int generateitemid(string shopid) { var generateditem = itemarray.elementat(new random().next(0, itemarray.count)).key; } how select this? it's not possible efficiently... first create static random @ class level... prevent non-random behaviour if run query on short period of time...
