[英]how can i get the directory of where i run my application exe file from?
For example let's say i installed my application at c:\\test Then from c:\\test i run my application test.exe So i want to get in a string in my program the directory c:\\test And if i run test.exe from d:\\hello So the directory in my program will be d:\\hello 例如,假设我在c:\\ test安装了我的应用程序然后从c:\\ test我运行我的应用程序test.exe所以我想在我的程序中输入一个字符串目录c:\\ test如果我运行test.exe来自d:\\ hello所以程序中的目录将是d:\\ hello
The installation is made by InnoSetup but thats just to set the directory i want to install to and to run from my application . 安装是由InnoSetup完成的,但这只是为了设置我想安装的目录并从我的应用程序运行。
In my application i did : 在我的应用程序中我做了:
testDir = Path.GetDirectoryName(Application.ExecutablePath);
And i tried before also : 我之前也尝试过:
testDir = Path.GetDirectoryName(Application.StartupPath);
In both cases im getting the same exception couldnt find the file... 在这两种情况下,我得到相同的异常无法找到该文件...
In the place i run my application from after installation there are two exe files one is the application the second is exe file the application need to work with. 在我从安装后运行我的应用程序的地方有两个exe文件,一个是应用程序,第二个是应用程序需要使用的exe文件。
So i want to get the directory from where i run my application exe file so i can also use the other exe file. 所以我想从我运行我的应用程序exe文件的目录,所以我也可以使用其他exe文件。

The code : 编码 :
class Ffmpeg
{
NamedPipeServerStream p;
String pipename = "mytestpipe";
byte[] b;
System.Diagnostics.Process process;
string ffmpegFileName;
string workingDirectory;
public Ffmpeg()
{
workingDirectory = Path.GetDirectoryName(Application.ExecutablePath);// +@"\workingDirectory";
ffmpegFileName = @"\ffmpeg.exe";
if (!Directory.Exists(workingDirectory))
{
Directory.CreateDirectory(workingDirectory);
}
ffmpegFileName = workingDirectory + ffmpegFileName;
Logger.Write("Ffmpeg Working Directory: " + ffmpegFileName);
}
public void Start(string pathFileName, int BitmapRate)
{
try
{
string outPath = pathFileName;
Logger.Write("Output Video File Directory: " + outPath);
Logger.Write("Frame Rate: " + BitmapRate.ToString());
p = new NamedPipeServerStream(pipename, PipeDirection.Out, 1, PipeTransmissionMode.Byte);
b = new byte[1920 * 1080 * 3]; // some buffer for the r g and b of pixels of an image of size 720p
ProcessStartInfo psi = new ProcessStartInfo();
psi.WindowStyle = ProcessWindowStyle.Hidden;
psi.UseShellExecute = false;
psi.CreateNoWindow = true;
psi.FileName = ffmpegFileName;
psi.WorkingDirectory = workingDirectory;
psi.Arguments = @"-f rawvideo -pix_fmt bgr0 -video_size 1920x1080 -i \\.\pipe\mytestpipe -map 0 -c:v libx264 -r " + BitmapRate + " " + outPath;
Logger.Write("ProcessStartInfo Arguments" + @"-f rawvideo -pix_fmt bgr0 -video_size 1920x1080 -i \\.\pipe\mytestpipe -map 0 -c:v libx264 -r " + BitmapRate + " " + outPath);
//psi.RedirectStandardOutput = true;
process = Process.Start(psi);
process.EnableRaisingEvents = false;
p.WaitForConnection();
}
catch (Exception err)
{
Logger.Write("Exception Error: " + err.ToString());
}
}
The exception is throw up on the line : 例外情况就是上线:
process = Process.Start(psi);
The exception is : 例外是:
6/9/2013--6:11 PM ==> Exception Error: System.ComponentModel.Win32Exception (0x80004005): The system cannot find the file specified
at System.Diagnostics.Process.StartWithCreateProcess(ProcessStartInfo startInfo)
at System.Diagnostics.Process.Start()
at System.Diagnostics.Process.Start(ProcessStartInfo startInfo)
at ScreenVideoRecorder.Ffmpeg.Start(String pathFileName, Int32 BitmapRate) in d:\C-Sharp\ScreenVideoRecorder\ScreenVideoRecorderWorkingVersion\Ffmpeg.cs:line 56
The ffmpeg.exe file and the application exe file both are in program files....etc I can run the application from there but the application cant find the ffmpeg.exe file in there ffmpeg.exe文件和应用程序exe文件都在程序文件....等我可以从那里运行应用程序但应用程序无法在那里找到ffmpeg.exe文件

Tried this code now : 现在尝试这个代码:
class Ffmpeg
{
NamedPipeServerStream p;
String pipename = "mytestpipe";
byte[] b;
System.Diagnostics.Process process;
string ffmpegFileName = @"\ffmpeg.exe";
string workingDirectory;
public Ffmpeg()
{
workingDirectory = Application.StartupPath; //Path.GetDirectoryName(Application.ExecutablePath);// +@"\workingDirectory";
if (!Directory.Exists(workingDirectory))
{
Directory.CreateDirectory(workingDirectory);
}
ffmpegFileName = Path.Combine(workingDirectory, ffmpegFileName);//@"\ffmpeg.exe";
Logger.Write("Ffmpeg Working Directory: " + ffmpegFileName);
}
public void Start(string pathFileName, int BitmapRate)
{
try
{
string outPath = pathFileName;
Logger.Write("Output Video File Directory: " + outPath);
Logger.Write("Frame Rate: " + BitmapRate.ToString());
p = new NamedPipeServerStream(pipename, PipeDirection.Out, 1, PipeTransmissionMode.Byte);
b = new byte[1920 * 1080 * 3]; // some buffer for the r g and b of pixels of an image of size 720p
ProcessStartInfo psi = new ProcessStartInfo();
psi.WindowStyle = ProcessWindowStyle.Hidden;
psi.UseShellExecute = false;
psi.CreateNoWindow = true;
psi.FileName = ffmpegFileName;
psi.WorkingDirectory = workingDirectory;
psi.Arguments = @"-f rawvideo -pix_fmt bgr0 -video_size 1920x1080 -i \\.\pipe\mytestpipe -map 0 -c:v libx264 -r " + BitmapRate + " " + outPath;

//psi.RedirectStandardOutput = true;
process = Process.Start(psi);
process.EnableRaisingEvents = false;
p.WaitForConnection();
}
catch (Exception err)
{
Logger.Write("Exception Error: " + err.ToString());
}
}
Same exception as above . 与上述相同的例外。
Assembly.GetExecutingAssembly().Location //is what you need here
The Path.GetDirectoryName()
method returns the directory path without trailing slash . Path.GetDirectoryName()
方法返回没有尾部斜杠的目录路径。 To build a file path using it, you have to add that yourself. 要使用它构建文件路径,您必须自己添加它。
Best is to let the framework do it for you, sometimes it's not the ordinary backslash: 最好是让框架为你做,有时它不是普通的反斜杠:
ffmpegFileName = Path.Combine(workingDirectory, ffmpegFileName);
