    As Naveen mentioned we need a proper error details or message you got.
    But as per your requirement, I feel that you need to take line by line as a parameter in a paragraph*(Scanned copy) kind. You can use the below query for taking string values of each line.

    string[] lines = theText.Split(new string[] { "\r\n", "\n" }, StringSplitOptions.None);
