Parameters
- index
- The zero-based index of a barcode for which the search will be made.
Return Value
>=0, the index of the first barcode in the array that is a duplicate of the barcode at the specified index; otherwise, this method will throw an exception.Example
For an example, refer to BarcodeData.IsDuplicated example.
Remarks
As an example, assume a call to the BarcodeEngine.Read method
is made to read ten barcodes in an array of BarcodeData.
Suppose the BarcodeData.IsDuplicated property is called
for the item at index 3 in the array, and TRUE is returned.
This indicates one or more barcodes in the array are duplicates of the specified item.
Calling this method returns the index of the first barcode in the array that is a duplicate
of the barcode at index 3 in the array.
Suppose this value is 0. The barcode present at index zero in the array is the first
duplicate of the barcode at index 3.
Calling BarcodeData.GetNextDuplicated method
with index set to 3 will return the index of the next barcode in the array that is a duplicate
of the barcodes at index 0 and 3. Suppose this value is 9. This means the barcodes at
index 0, index 3, and index 9 of the array are all duplicates.
