c# remove all white spaces from string

Question

I have an sql string retreiving data for three columns and I dont want any space in betweeen these columns. I want to remove space between columns.

 string stringSql = " SELECT distinct  " +
                   "'" + comboBox6.Text + "' as RecordType" +
                 " , left([Claimant Name] +' ',29) " +
                " , left([Claimant Address1] +' ',29)  " +
                " , left([Claimant Address2] +' ',29) as ClaimantAddress2 " +

My Client requirment is like

**1xyz1dundas**

MY output is like

**1 xyz 1 dundas**

Your question is unclear. What if the claimant name or address contains a space in between. Should we remove that also e.g. `Street 1 Of July` should become `Street1OfJuly` or do you want just remove the ending spaces? Another point to know if your columns are of CHAR datatype or VARCHAR/NVARCHAR — Steve, Feb 28 '14 at 09:31

In case you want to remove whitespaces (not just ordinary spaces ' ', but, say, tabluations '\t') you can use LINQ:

  stringSql = new String(stringSql.Where(x => !Char.IsWhiteSpace(x)).ToArray());
