There are many ways to read and write to text files. We will see one option here. Be sure to add using System.IO namespace.
This is a function to write to a Text File.
private bool writeToTextFile()
{
bool success = true;
//path and filename
string fileName = Server.MapPath("abc.txt");
//data to be written in the file
//\r\n is to insert a new line
string data = "This is the first line \r\n" +
"This is the second line \r\n\r\n" +
"This is the third line";
try
{
File.WriteAllText(fileName, data);//write the data to the text file
}
catch (Exception e)
{
Response.Output.Write(e.Message);
success = false;
}
return success;
}
In the above function,\r\n is used to insert a new line.
This function is used to read from text file.
private bool readFromTextFile()
{
bool success = true;
//path and filename
string fileName = Server.MapPath("abc.txt");
try
{
string data = File.ReadAllText(fileName);//read from text file
data = data.Replace("\r\n", "");//\r\n is replaced by
Response.Output.Write(data);
}
catch (Exception e)
{
Response.Output.Write(e.Message);
success = false;
}
return success;
}
