Answer 1

You can put on your form button and create click handler to it with the following code:
private void buttonGetFile_Click(object sender, EventArgs e)
{
OpenFileDialog dialog = new OpenFileDialog();
dialog.Filter = "Text files | *.txt"; // file types, that will be allowed to upload
dialog.Multiselect = false; // allow/deny user to upload more than one file at a time
if (dialog.ShowDialog() == DialogResult.OK) // if user clicked OK
{
String path = dialog.FileName; // get name of file
using (StreamReader reader = new StreamReader(new FileStream(path, FileMode.Open), new UTF8Encoding())) // do anything you want, e.g. read it
{
// ...
}
}
}

Please refer to this tutorial for raw HTTP POST:
http://msdn.microsoft.com/en-us/library/debx8sh9.aspx
Reference to WebClient class of .NET:
http://msdn.microsoft.com/en-us/library/system.net.webclient(v=vs.80).aspx
A simple HTTP POST can be done like this:
string Upload_File_Content = ...;
string Url = ...;
using (var Http_Client = new WebClient()) {
var Post_Data = new NameValueCollection();
Post_Data["upload_file"] = Upload_File_Content;
var Response = Http_Client.UploadValues(Url,"POST",Post_Data);
}
