static DataTable stulist ()
{
	DataTable dt = new DataTable ();
	Dt. Columns.Add ("Student name");
	String Sfilepath = String. Empty;

	The path of the student list

	FileStream fs = new FileStream (Sfilepath, FileMode.Open);
	"GB2312" is used to display Chinese characters, to write other words, will display garbled
	StreamReader reader = new StreamReader (FS, unicodeencoding.getencoding (" GB2312 "));

	One line reads while

		DataRow dr = dt. NewRow ();
		dr["Student Name" = Sstuname;
