Application of generics in reading CVS data

CVS is a lightweight database, and text is separated by commas. In combination with generics, the method for reading this file is as follows:

 

Code

  Public  List  <  Dictionary  <  String  ,  String  >  Getdata (  String Filepath,  Out  List  <  String  >  Column)
{
Column  =     New  List  <  String  >  ();
List  < Dictionary  <  String  ,  String  >  Data  =     New  List  <  Dictionary  <  String  ,  String >  ();
  String  Strline  =     ""  ;
  String  [] Strarray;
Streamreader SR  =     New  Streamreader (filepath );
Strline  =  Sr. Readline ();
 If  (Strline  =     Null     |  Strline  =     ""  )
{
  Return     New  List  < Dictionary  <  String  ,  String  >  ();
}
Strarray  =  Strline. Split (  '  ,  '  );
  Foreach  (  String  Item In  Strarray)
{
Column. Add (item );
}
Strline  =  Sr. Readline ();
  While  (Strline  ! =     Null  )
{
Strarray  =  Strline. Split (  '  ,  ' );
Dictionary  <  String  ,  String  >  Dict  =     New  Dictionary  <  String  ,  String  >  ();
 For  (  Int  I  =     0  ; I  <  Column. Count; I  ++  )
{
Dict. Add (column [I], strarray [I]);
}
Data. Add (dict );
Strline  =  Sr. Readline ();
}
Sr. Close ();
 Return  Data;
} 

 

The call method is as follows:

List <string> column;
List <dictionary <string, string> date = getdata (this. textbox1.text. Trim (), Out column );
String STR = "";
Foreach (Dictionary <string, string> item in date)
{
Foreach (string Item1 in column)
{
STR + = item [Item1] + "";
}
STR + = environment. newline;

}
This. textbox2.text = STR;
