## Parameter Details

| ExpectedBarcodesCount Parameter Details |
| :--------------------------------- |
| **Type**<br>*int* |
| **Range**<br>[0, 0x7fffffff] |
| **Default Value**<br>0 |

**Remarks**

- 0: detects at least one barcode.
- N ( N > 0 ): detects N barcodes.
- Dynamsoft Barcode Reader works as a loop trying different parameters to detect barcodes as many as possible. If ExpectedBarcodesCount is 0, the loop stops after a loop round finishes and detects at least one barcode. If ExpectedBarcodesCount is N, the loop stops once N barcodes are detected.
- ExpectedBarcodesCount applies to each page when decoding a multi-page file.
