C# Data Table count rows.

Hello.

I am using SimpleSql for my game.

However, I have a menu - I need to know how many rows will be returned.

 Rect rScrollFrame = new Rect(listMargin.x, listMargin.y, listSize.x, listSize.y);
         Rect rList        = new Rect(0, 0, rowSize.x, numRows*rowSize.y);
         
         scrollPosition = GUI.BeginScrollView (rScrollFrame, scrollPosition, rList, false, false);
             
         Rect rBtn = new Rect(0, 0, rowSize.x, rowSize.y);
         
         for (int iRow = 0; iRow < numRows; iRow++)
         {
                // draw call optimization: don't actually draw the row if it is not visible
             if ( rBtn.yMax >= scrollPosition.y && 
                  rBtn.yMin <= (scrollPosition.y + rScrollFrame.height) )
                {
                 bool fClicked = false;
                    string rowLabel = dt.rows[iRow]["WhiskyName1"].ToString();
                    
                    if ( iRow == selected )
                    {
                     fClicked = GUI.Button(rBtn, rowLabel, rowSelectedStyle);
                    }
                    else
                 {
                        fClicked = GUI.Button(rBtn, rowLabel);
                 }
                 
                 // Allow mouse selection, if not running on iPhone.
                 if ( fClicked && Application.platform != RuntimePlatform.IPhonePlayer )
                 {
                    Debug.Log("Player mouse-clicked on row " + iRow);
                 }
                }
                            
             rBtn.y += rowSize.y;
         }
         GUI.EndScrollView();
     }

Currently numRows is a hard coded static int. This I would like to change.

How do I find how many rows are in a c# data table.

I have tried

 dt.Rows.Count

To no avail
