Parsing in VB.Net e C#

Analizziamo le metodologie di parsing in VB.Net e C#:

• Read to end con linguaggio VB.NET

Imports System.IO

Public Class "nome class"

Private Sub Button1_Click(Sender As Object, e As EventArgs) Handles Button1.Click

Me.RichTextBox1.Text = “nometextbox”

Dim parser As New OpenFileDialog

parser.ShowDialog()

Dim NomeFile As String = parser.FileName

Me.RichTextBox1.AppendText(Environment.NewLine & NomeFile)

Dim s As New StreamReader(NomeFile)

Dim All As String = s.ReadToEnd

Me.RichTextBox1.AppendText(Environment.NewLine & All)

End Sub

End Class

Esempio:

• Read to end con linguaggio C#

using Microsoft.VisualBasic;

using System;

using System.Collections;

using System.Collections.Generic;

using System.Data;

using System.Diagnostics;

using System.IO;

public class "nome class"

{

private void Button1_Click(object Sender, EventArgs e)

{

this.RichTextBox1.Text = “nometextbox”;

OpenFileDialog parser = new OpenFileDialog();

parser.ShowDialog();

string NomeFile = parser.FileName;

this.RichTextBox1.AppendText(Environment.NewLine + NomeFile);

StreamReader s = new StreamReader(NomeFile);

string All = s.ReadToEnd;

this.RichTextBox1.AppendText(Environment.NewLine + All);

}

}

Esempio:

• Read line con linguaggio VB.NET

Imports System.IO

Public Class "nome class"

Private Sub Button1_Click(Sender As Object, e As EventArgs) Handles Button1.Click

Me.RichTextBox1.Text = “nometextbox”

Dim parser As New OpenFileDialog

parser.ShowDialog()

Dim NomeFile As String = parser.FileName

Me.RichTextBox1.AppendText(Environment.NewLine & NomeFile)

Dim s As New StreamReader(NomeFile)

Dim Contatore As Integer = 1

Do

Dim RigaDelFile As String = s.ReadLine

Me.RichTextBox1.AppendText(Environment.NewLine & “Riga #” & COntatore & “: ” & RigaDelFile)

Contatore = Contatore + 1

Loop Until s.EndOfStream

End Sub

End Class

Esempio:

• Read line con linguaggio C#

using Microsoft.VisualBasic;

OpenFileDialog parser = new OpenFileDialog();

parser.ShowDialog();

string NomeFile = parser.FileName;

this.RichTextBox1.AppendText(Environment.NewLine + NomeFile);

StreamReader s = new StreamReader(NomeFile);

int Contatore = 1;

do {

string RigaDelFile = s.ReadLine;

this.RichTextBox1.AppendText(Environment.NewLine + “Riga #” + COntatore + “: ” + RigaDelFile);

Contatore = Contatore + 1;

} while (!(s.EndOfStream));

}

}
