Answer 1

To create users in Salesforce from an external client (in this case your C# app), you will need to use one of the Salesforce APIs. Salesforce provides many type of apis (Enterprise API, Partner API, Rest API etc).

Using one of these API, you will insert a User record, that should create the user.

All of these APIs needs a session id, which you can get it from Partner API Login method.

Here is an example on how to create a record using Rest API.

Answer 2

In your code, you are Creating a LEAD instead of USER .

go thru the User object in the link and assign the fields in your UI to the fields of the user object and pass it to the CREATE method same way as u r doing for LEAD.
