Convert a TXT file to Dataset

If you need to convert the TXT file to the dataset of the memory table, the TXT file is in a specific format, In the file, a record is a line, and the field is | "Split ( Note: after the last field "| ") Each field is the corresponding field in the database in sequence.
Example:
ID Number | line code | Station Encoding | Running Mode | mode setting date | mode setting time
1 | 98 | 9821 | 06 | 20070913 | 211835 |
The method is as follows:

/**/ /**/ /**/ ///   <Summary>
/// File Loading
///   </Summary>
///   <Param name = "filepath"> Path with file name </Param>
///   <Param name = "tablename"> Custom table name </Param>
///   <Param name = "fieldsinarray"> Custom table fields </Param>
///   <Returns> Dataset </Returns>

Public   Static Dataset textfileloader ( String Filepath, String Tablename, String [] Fieldsinarray)
{
Dataset DS =   New Dataset ();
Datatable dt =   New Datatable (tablename );

Filestream FS = File. Open (filepath, filemode. Open, fileaccess. Read );
Streamreader SR =   New Streamreader (FS );

For ( Int I =   0 ; I < Fieldsinarray. length; I ++ )
{
DT. Columns. Add (NewDatacolumn (fieldsinarray [I],Typeof(String)));
}

String Strread;
Bool Flag =   True ;

While (FLAG)
{
Strread = Sr. Readline ();

If ( ! String . Isnullorempty (strread ))
{
String [] Aryvale = Strread. Split ( ' \ T ' );

Datarow Dr = DT. newrow ();
For ( Int K =   0 ; K < Aryvale. length; k ++ )
{
Dr [fieldsinarray [k]=Aryvale [k];
}
DT. Rows. Add (DR );
}
Else
{
Flag= False;
}
}

DS. Tables. Add (DT );
Return DS;
