Remove a special character from a file and save in same file.

Harish Sharma

I have to read a file, search for a special character 'ç', its ascii equivalent is 0231 (c-cedilla) and replace it with a space. I have tried File class's ReadAllBytes / ReadAllText / ReadAllLines with Encoding.ASCII to read the file, but when it comes to this special character, it reads as '?' whose ascii equivalent is 63. How to do this? Any kind of help will be appreciated. Thanks in advance harry

// Write you all text in txt File and then Save the Text File with UTF8 encoding in Notepad

using System.IO;

private void button1_Click(object sender, EventArgs e)
        {
            StreamReader sr = new StreamReader("sample.txt",true);
            string str = sr.ReadToEnd();
            sr.Close();
            StringBuilder sb = new StringBuilder();
            foreach (char c in str)
            {
                if (c == 'ç')
                {
                    char x = ' ';
                    sb.Append(x);
                }
                else
                {
                    sb.Append(c);
                }
            }

            string final = sb.ToString();

            StreamWriter sw = new StreamWriter("sample.txt",false,Encoding.UTF8);
            sw.Write(final);
            sw.Close();

        }
