One, C # client

To make it easier to explain, I simply simplified, and a submit button was just fine.

Second, the need to submit pictures

The picture is stored in my e-packing directory under the ~~~~~ (paste a random picture)

Path = @e:head.jpg;

Third, PHP service side

After receiving the picture, store it to, path = @c:loginlog;

Appendix:

C # side code:

C # Interface Simple code ~~~~~ (this code can be skipped ~~~~~)
