Read and write from Text file in Asp.Net

Here we will discuss how we can read and write from a text file in Asp.net.

You will get a string array while reading all the lines and it will store one line to an array element in C#.Net.

And once you will get the array then you can modify what ever you want and then you can Write the whole array to the file.

Here is the code:

            string[] Details = new string[0];
            string strPath = @"C:\myfile.txt";
            if (File.Exists(strPath))
                Details = File.ReadAllLines(strPath);

            //Here you will get in the form of array
            Details[0] = "password^###~" + "What ever text you want";
            //Here you can write the whole array to the file.

            File.WriteAllLines(strPath, Details);
