Public Readonly Property ColumnCount As Short
C#
public short ColumnCount { get;}
The number of columns in the index.
Column ordinals in indexes range from 1 to ColumnCount, inclusive.
Column ordinals and count may change during a schema upgrade. Column ordinals from an index are different than the column IDs in a table or another index, even if they refer to the same physical column in a particular table.
