'Declaration Public Property LineSpacingAuto As Nullable(Of Single)
public Nullable<float> LineSpacingAuto {get; set;}
The LineSpacingAuto property provides a way for the developer to space lines such that the actual value is automatically calculated by the document consumer based on the line height for the associated paragraph. An explicit value can be specified for line spacing using the LineSpacingExact property.
The LineSpacingExact , LineSpacingMinimum and LineSpacingAuto properties are mutually exclusive; when one property is set, the others are not applicable.
In the case where more than one of the properties is explicitly set, the order of precedence is as follows:
Unlike the LineSpacingExact and LineSpacingMinimum properties, this property's value is always expressed as a multiple of the line height for the paragraph, and is never converted based on the value of the associated WordDocumentWriter's Unit property.
For example, to apply vertical spacing between lines of text that is equal to .5 times the height of the line itself, assign a value of .5 to the LineSpacingAuto property, and leave the values of the LineSpacingExact and LineSpacingMinimum properties at their respective defaults.
