Asp.Net C# Code to write and read text file

//include namespace
using System;
//include namespace
using System.IO;

    protected void btnliveWrite_Click(object sender, EventArgs e)
    {
        FileWrite("liveDataFile.txt");
    }
    protected void btnliveRead_Click(object sender, EventArgs e)
    {
        livetxtredContent.Text = FileReadForm("liveDataFile.txt");
    } 
    private void FileWrite(String liveFileNm)
    {
        string getFPath = Path.Combine(Request.PhysicalApplicationPath, string.Format("{0}\{1}", "uploadFolder", liveFileNm));
        //OR string getFPath = Path.Combine(Server.MapPath("~/uploadFolder"), liveFileNm);
        using (StreamWriter swrite = new StreamWriter(getFPath))
        {
            swrite.WriteLine(livetxtPutContent.Text);
        }
    }
    public string FileReadForm(String liveFileNm)
    {
        string fileText = string.Empty;
        string getFPath = Path.Combine(Request.PhysicalApplicationPath, string.Format("{0}\{1}", "uploadFolder", liveFileNm));
        //OR string getFPath = Path.Combine(Server.MapPath("~/uploadFolder"), liveFileNm);

        if (File.Exists(getFPath))
        {
            using (StreamReader sr = new StreamReader(getFPath))
            {
                fileText = sr.ReadToEnd();
            }
        }
        return fileText;
    }

IMP Note:

In the above simple FileWrite simple function the used to StreamWriter class will make the simple text file if it this path does not exist so over write the created file if it does exist.

Asp.Net VB Code to write and read text file

Imports System.Data

Imports System.IO

    Protected Sub btnliveRead_Click(sender As Object, e As EventArgs)
        livetxtredContent.Text = FileReadForm("liveDataFile.txt")
    End Sub
    Protected Sub btnliveWrite_Click(sender As Object, e As EventArgs)
        FileWrite("liveDataFile.txt")
    End Sub
    Public Function FileReadForm(liveFileNm As [String]) As String
        Dim fileText As String = String.Empty
        Dim getFPath As String = Path.Combine(Request.PhysicalApplicationPath, String.Format("{0}\{1}", "uploadFolder", liveFileNm))
        'OR string getFPath = Path.Combine(Server.MapPath("~/uploadFolder"), liveFileNm);

        If File.Exists(getFPath) Then
            Using sr As New StreamReader(getFPath)
                fileText = sr.ReadToEnd()
            End Using
        End If
        Return fileText
    End Function
    Private Sub FileWrite(liveFileNm As [String])
        Dim getFPath As String = Path.Combine(Request.PhysicalApplicationPath, String.Format("{0}\{1}", "uploadFolder", liveFileNm))
        'OR string getFPath = Path.Combine(Server.MapPath("~/uploadFolder"), liveFileNm);
        Using swrite As New StreamWriter(getFPath)
            swrite.WriteLine(livetxtPutContent.Text)
