我自己做了一个概念验证来测试这个工具来管理音频文件。我的目的是改变采样率。我的第一个例子很好用!
public class Test
{
public void SoxMethod()
{
var startInfo = new ProcessStartInfo();
startInfo.FileName = "C:\\Program Files (x86)\\sox-14-4-2\\sox.exe";
startInfo.Arguments = "\"C:\\Program Files (x86)\\sox-14-4-2\\input.wav\" -r 16000 output.wav";
startInfo.WindowStyle = ProcessWindowStyle.Hidden;
startInfo.UseShellExecute = false;
startInfo.CreateNoWindow = false;
startInfo.WorkingDirectory= "C:\\Program Files (x86)\\sox-14-4-2";
using (Process soxProc = Process.Start(startInfo))
{
soxProc.WaitForExit();
}
}
}
但是当我想在我的bin文件夹中添加此工具但我得到异常时:目录名无效
public void SoxMethod()
{
var startInfo = new ProcessStartInfo();
startInfo.FileName = "bin/sox-14-4-2/sox.exe";
startInfo.Arguments = "bin/sox-14-4-2/input.wav -r 16000 output.wav";
startInfo.WindowStyle = ProcessWindowStyle.Hidden;
startInfo.UseShellExecute = false;
startInfo.CreateNoWindow = false;
startInfo.WorkingDirectory= "bin/sox-14-4-2";
using (Process soxProc = Process.Start(startInfo))
{
soxProc.WaitForExit();
}
}
也许它很明显,但我不知道我做错了什么
答案 0 :(得分:1)
您的工作目录设置错误。请改用AppDomain.CurrentDomain.BaseDirectory
。这将使进程从bin
文件夹开始。然后,将您的文件和参数替换为 relative 到工作目录(从而删除路径的bin
部分。)
public void SoxMethod()
{
var startInfo = new ProcessStartInfo();
startInfo.FileName = "sox-14-4-2/sox.exe";
startInfo.Arguments = "sox-14-4-2/input.wav -r 16000 output.wav";
startInfo.WindowStyle = ProcessWindowStyle.Hidden;
startInfo.UseShellExecute = false;
startInfo.CreateNoWindow = false;
startInfo.WorkingDirectory = AppDomain.CurrentDomain.BaseDirectory;
using (Process soxProc = Process.Start(startInfo))
{
soxProc.WaitForExit();
}
}
