解决 IronBarcode 中的运行时复制异常

Updated: 2026年5月9日

在某些罕见情况下，由于我们特殊机器学习模型的 DLL 文件没有正确复制，会导致此错误。下面的解决方案可以解决这个一次性错误。

Machine learning DLLs were not successfully automatically copied from the runtimes directory. This may occur on various operating systems or frameworks...

解决方案

解决该问题的方法是首先导航到runtimes文件夹。在您的解决方案中，这将位于/bin/Debug/net6.0/runtimes下（Debug是一个示例，请遵循您设置的配置）。 (If you're using a different target framework, replace net6.0.)
您将看到所有受支持的平台和操作系统在/bin/Debug/net6.0/目录。
禁用机器学习扫描也可以防止出现此错误。但是，您应该注意，关闭 ML 扫描可能会使某些条形码更难被检测到，因为此功能有助于条形码检测。

// Define scanning options, disabling machine learning for basic scan only
var myOptionsExample = new BarcodeReaderOptions
{
    // ScanMode is set to only use the basic scan, without ML-enhanced features
    ScanMode = BarcodeScanMode.OnlyBasicScan
};

// Perform barcode reading with the specified options
var results = BarcodeReader.Read("barcode.png", myOptionsExample);
