File.Create returns a FileStream object which holds your file. You should use this object for further task.

var fileStream = File.Create(NameTb.Text + ".txt");
//... do all the writing using fileStream
fileStream.Close();

or you could do just

var fs = File.Create(NameTb.Text + ".txt");
fs.Close();
TextWriter tw = new StreamWriter(NameTb.Text + ".txt"); 
tw.WriteLine("The very first line!");
tw.Close();
