Underline Property (IConditionalFormat)

Gets or sets the underline type for the conditional format.
Property Underline As ExcelUnderline
Dim instance As IConditionalFormat
Dim value As ExcelUnderline
instance.Underline = value
value = instance.Underline
ExcelUnderline Underline {get; set;}
Similar to Underline, we can use IsStrikeThrough to strike out values in the cells within conditional formatting range.
Data in the cells can be given underline with the help of conditional formats. To give underline Underline property should be set to any of the value in the ExcelUnderline enumeration. Here for example, we set ExcelUnderline.Double to Underline property.

            format.Underline = ExcelUnderline.Double;
            //Save and Dispose.
