[RESOLVED] Convert string to string literal verbatim

[stephsh]

I have converted a PDF to byte[]. I then converted that to string since it specifically to be saved in the database as nvarchar(MAX). I would however like to know how to convert it to string literal verbatim (following the format of @"text here") to enable me to escape the characters present in the string so that it can be inserted into the database.

protected void SavePDFtoDB()
        {
            // Save PDF to byte[]
            mBytePDF = File.ReadAllBytes(msPath);

            // Convert byte[] to string
            String contents = ByteArrayToString(mBytePDF);

            // Save PDF in Database in form of string
            MainTable lMainTable = new MainTable();
            lMainTable.Date = DateTime.Now;
            lMainTable.Archive = 1;
            lMainTable.Text = @contents; // PROBLEM: Trying to convert to string literal verbatim
            SData.mWebService.setMainTable(lMainTable);
        }

        private string ByteArrayToString(byte[] arr)
        {
            System.Text.ASCIIEncoding enc = new System.Text.ASCIIEncoding();
            return enc.GetString(arr);
        }

Any help would be much appreciated!
