Gets or sets a value that indicates whether the column automatically increments the value of the column for new rows added to the table.
Assembly: System.Data (in System.Data.dll)
If the type of this column is not Int16, Int32, or Int64 when this property is set, the DataType property is coerced to Int32. An exception is generated if this is a computed column. The Expression property is set. The incremented value is used only if the row's value for this column, when added to the columns collection, is equal to the default value.
You can create a new row using the ItemArray property of the DataRow class and passing in an array of values. This is a potential problem for a column with its set to true, because its value is generated automatically. To use the ItemArray property, place null in the column's position in the array. For more information, see the ItemArray property of the DataRow class.
When the AutoIncrementStep value is added to the current value, the overflow check is suppressed.
