Sets or returns the percentage of standard size by which the worksheet will be magnified or reduced. Set this property to a value between 10 and 400.

 public int ZoomPercentage{ get; set; }

Public Property ZoomPercentage() As Integer

By default the worksheet will have a ZoomPercentage of 100, corresponding to the standard zoom level. Adjusting this property to a larger number will magnify the worksheet, making it so that the contents are larger but less can be displayed on the screen. Setting this property to a smaller number will zoom out, revealing more of the worksheet.

Thrown if you set the property to a value that is less than 10 or greater than 400
