Showing error even if i have given required reference...?

Question

I am getting following error when i am trying to build my c# project:

The type or namespace name xyz could not be found (are you missing a using directive or an assembly reference?)

I have given reference of required file . don't know why this error is coming again and again?

Thanks in advance

@dcastro It is not [using statement](http://msdn.microsoft.com/en-us/library/yh598w02.aspx), it is [using directive](http://msdn.microsoft.com/en-us/library/sf0df423.aspx). These are 2 different things `;)` — Soner Gönül, Dec 16 '13 at 09:18

You probably need the using directive too. In the file that is throwing the error, add:

using xyz;

Obviously substituting xyz with the correct namespace.

Try cleaning and then rebuilding your entire solution - it may be that the `using` directive is needed in other files too... – DGibbs Dec 16 '13 at 09:22
Cleaned and rebuild but nothing improved .. still shoeing same error..!! – shubhendu Dec 16 '13 at 09:28
Can you post the full error message, and then the `using` block from the file that is referencing? – DGibbs Dec 16 '13 at 09:34
yes... here it is: _Error 2 The type or namespace name 'SensorControl' could not be found (are you missing a using directive or an assembly reference?) C:\Documents and Settings\Anita\My Documents\Visual Studio 2010\Projects\WFM2_V1.6\WFM2_V1.6\settingFrm.cs 12 7 WFM2_V1.6_ and using block is **using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; using System.Threading; using SensorControl; using SensorControl.Sensors; using PaintAnalysis.Common;** – shubhendu Dec 16 '13 at 09:36
Could be that the project has the wrong [client profile](http://stackoverflow.com/questions/4764978/the-type-or-namespace-name-could-not-be-found?rq=1) – DGibbs Dec 16 '13 at 09:55
It's explained in the link I provided. – DGibbs Dec 16 '13 at 10:14
