您好，我正在编写代码以使用 mp4box.exe 对 mp4 视频进行一些编辑
我想执行这个命令行：
"D:\Work\Me\CloudContentUpload\trunk\ContentUploading Current\bin\Debug\Mp4Box\Mp4Box.exe" -isma -inter 500 "C:\Users\Abdullah\Desktop\videoo\amr khaled - Asmaa_elmogeb\Asmaa_elmogeb(1).mp4"
当我在命令行上手动运行此命令时成功执行
但我尝试使用以下 C# 代码执行它：
public string ExecuteCommandSync(object command)
{
try
{
// create the ProcessStartInfo using "cmd" as the program to be run,
// and "/c " as the parameters.
// Incidentally, /c tells cmd that we want it to execute the command that follows,
// and then exit.
System.Diagnostics.ProcessStartInfo procStartInfo =
new System.Diagnostics.ProcessStartInfo("cmd", "/c " + command);
// The following commands are needed to redirect the standard output.
// This means that it will be redirected to the Process.StandardOutput StreamReader.
procStartInfo.RedirectStandardOutput = true;
procStartInfo.UseShellExecute = false;
// Do not create the black window.
procStartInfo.CreateNoWindow = true;
// Now we create a process, assign its ProcessStartInfo and start it
System.Diagnostics.Process proc = new System.Diagnostics.Process();
proc.StartInfo = procStartInfo;
proc.Start();
// Get the output into a string
string result = proc.StandardOutput.ReadToEnd();
// Display the command output.
return result;
}
catch (Exception objException)
{
return objException.Message;
}
}
返回的结果是空字符串！！
