Abort

BarCodeReader.Abort method

函数请求从其他线程终止当前识别会话。 Abort 是不可阻塞的方法，并在调用后立即返回控制。识别过程过长时应使用该方法。

public void Abort()

例子

这个示例展示了如何从其他线程调用 Abort 函数

[C#]
private static void ThreadRecognize(object readerObj)
{
    BarCodeReader reader = (BarCodeReader)readerObj;
    foreach (BarCodeResult result in reader.ReadBarCodes())
    {
        Console.WriteLine("BarCode Type: " + result.CodeType);
        Console.WriteLine("BarCode CodeText: " + result.CodeText);
    }
}

BarCodeReader reader = new BarCodeReader(@"c:\test.png", DecodeType.Code39Standard, DecodeType.Code128);
Thread thread1 = new Thread(ThreadRecognize);
thread1.Start(reader);
Thread.Sleep(100);
reader.Abort();
[VB.NET]
Private Shared Sub ThreadRecognize(readerObj As Object)
    Dim reader As BarCodeReader = readerObj
    For Each result As BarCodeResult In reader.ReadBarCodes()
        Console.WriteLine("BarCode Type: " + result.CodeTypeName)
        Console.WriteLine("BarCode CodeText: " + result.CodeText)
    Next
End Sub

Dim reader As New BarCodeReader("c:\test.png", DecodeType.Code39Standard, DecodeType.Code128)
Dim thread1 As New Thread(AddressOf ThreadRecognize)
thread1.Start(reader)
Thread.Sleep(100)
reader.Abort()
