NAudio 循环 n 次

问题描述

在这里使用 NAudio 循环辅助类:
https://markheath.net/post/looped-playback-in-net-with-naudio

我试图让它循环 N 次而不是无限循环。我尝试修改 Read() 来自:

public override int Read(byte[] buffer,int offset,int count)
{
    int totalBytesRead = 0;
    while (totalBytesRead < count)
    {
        int bytesRead = sourceStream.Read(buffer,offset + totalBytesRead,count - totalBytesRead);
        if (bytesRead == 0)
        {
            if (sourceStream.Position == 0 || !EnableLooping)
            {
                // something wrong with the source stream
                break;
            }
            // loop
            sourceStream.Position = 0;
        }
        totalBytesRead += bytesRead;
    }
    return totalBytesRead;
}

致:

public override int Read(byte[] buffer,int count)
{
    int totalBytesRead = 0;

    for (var i = 0; i < 3; i++)
    {
        int bytesRead = sourceStream.Read(buffer,count - totalBytesRead);
        totalBytesRead += bytesRead;
    }

    return totalBytesRead;
}

但这似乎不会循环播放样本(仅播放一次)。

代码无限循环:

public override int Read(byte[] buffer,int count)
{
    int totalBytesRead = 0;

    for (var i = 0; i < 3; i++)
    {
        var bytesRead = sourceStream.Read(buffer,count - totalBytesRead);
        totalBytesRead += bytesRead;
        sourceStream.Position = 0;
    }

    return totalBytesRead;
}

有谁知道我如何循环 n 次?
