            sr = new StreamWriter(filename, true);
            string seperator = "";
            StringBuilder builder = new StringBuilder();


                foreach (DataColumn col in table.Columns)
                {

                    builder.Append(seperator).Append(col.ColumnName);

                    seperator = seperateChar;
                }

                sr.WriteLine(builder.ToString());


            foreach (DataRow row in table.Rows)
            {

                seperator = "";
                builder = new StringBuilder();
                foreach (DataColumn col in table.Columns)
                {

                    builder.Append(seperator).Append(row[col.ColumnName]);
                    seperator = seperateChar;

                }

                sr.WriteLine(builder.ToString());

            }

        }

        finally
        {

            if (sr != null)
            {

                sr.Close();

            }

        }

    }

You have text encoding confusion. In other words, the encoding of the data you are writing to the CSV file does not match the encoding expected by the CSV viewer (e.g. Excel).

For more detail see

Character Encoding and the ’ Issue

In the particular ’ example, this is a typical CP1252 representation of the Unicode Character ‘RIGHT SINQLE QUOTATION MARK’ (U+2019) ’ which was been read using UTF-8. In UTF-8, that character exist of the bytes 0xE2, 0x80 and 0x99. If you check the CP1252 codepage layout, then you’ll see that those bytes represent exactly the characters â, € and ™.
