Recently, because the project needs to implement C # submit text and data to the server, so the study of C # PHP data transfer;
Below is an example to demonstrate, C # post text + picture, PHP side receive;
Post submission Data core code (post data submission)

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 ~~~~~)
