我们可以使用BarcodeReader类读取条形码。 最简单的方法是使用BarcodeReader.Read方法。 IronBarcode还具有用于多线程异步编程的ReadAsync方法。
同步与异步方法
Read方法在需要立即结果时是简单易用的，并且在主线程上被调用。
ReadAsync方法用于异步执行，允许程序在等待条形码读取完成时继续执行其他任务。
BarcodeReaderOptions
true，读取器将寻找图像中的多个条形码。
EnhanceAccuracy：提高精度，但速度降低。
SpeedUp：提高读取效率，这可能对快速处理大量图像有用。 然而，如果设置为true，这可能会降低精度。
