在将HTML字符串插入到Excel单元格之前，从其中删除换行符

Question

Im using Microsoft Visual Studio to extract data from a database into excel. The data in the database field looks as follows:

RISK TITLE &amp; DESC.:this is a test to see if the data disappears. <br /> <ol> <li>mvkf</li> <li>fmjdk </li> </ol> kfhjl<br /> <ul> <li>jfidj </li> <li>fjdilfjwkl </li> </ul> fnhdjkfhkd<br /> <a href=http://islhnweb/ target=_blank>fhsdklfjsd<br /> </a>jdfkls

When i extract the data into excel each line of text is wrritten into a seperate row as follows:

Row 6 : RISK TITLE & DESC.:this is a test to see if the data disappears.
Row 7 :
Row 8 : 1. mvkf
Row 9 : 2. fmjdk
Row 10 :
Row 11 : kfhji
Row 12 :
Row 13 : jfidj
Row 14 : fjdilfjwkl
Row 15 :
Row 16 : fnhdjkfhkd
Row 17 : (link of)fhsdkfjsd
Row 18 : (link of) jdfkls

I need to have the whole lot of the data in one cell in 1 row, not over multiple rows.

My code is:

case "longtext":
    tCell.Text = RLB(datarow[defrow["ColumnName"].ToString()].ToString());
    tCell.Width = 500;
    break;

Next part is as follows:

    protected string RLB(string strHTML)
    {
       StringWriter myWriter = new StringWriter();
       HttpUtility.HtmlDecode(strHTML, myWriter);
       string strResult = myWriter.ToString();
       return strResult;
    }

All help is appreciated.

Answer 1

You can try the following:

tCell.Text = RLB(datarow[defrow["ColumnName"].ToString()].ToString()).Replace(System.Environment.NewLine, String.Empty);

If it does not solve your problem, try to remove (by adding more .Replace() methods) other escape sequences, like: \\f (Formfeed); \\r (Carriage return); \\v (Vertical tab).

Hope this will help. Best regards,

Removing the <br /> elements would probably go a fair ways toward fixing this. The <ol> elements seem to be causing the remaining problems, so those might need to be sacrificed, although since Excel does have in-cell formatting they can probably be edited back in with a bit of work after the insertion.
