//Code snippet to read the textfile(gautam.txt)




string filename="gautam.txt"; 
StreamReader myReader = new StreamReader(filename); 
StringBuilder strBuilder = new StringBuilder(); 
string str = myReader.ReadLine(); 
while( str != null ) 
{ 
	strBuilder.Append(str + "\n"); 
	str = myReader.ReadLine(); 
} 
myReader.Close(); 
txtMyTextBox.Text = strBuilder.ToString();

//Code snippet to write the data from textbox(txtMyTextBox) to textfile(gautam.txt).For this we have to change the property txtMyTextBox.ReadOnly to false

string filename="gautam.txt";
StreamWriter myWriter = new StreamWriter(filename, false);
myWriter.WriteLine(txtMyTextBox.Text);
myWriter.Close();
