C# spaces in path

Question

I've seen tens of questions and answers concerning this subject but I still couldn't solve my problem.

I'm using an external ffmpeg converter in my code and I'm passing a file path as an argument like this:

OutputPackage oo = converter.ConvertToFLV(@"C:\Users\user\Documents\test Video\video.wmv");

When there is no space in "test Video" folder name ,then it works fine. But when it's like above I get an error that C:\Users\user\Documents\test is not a valid path.

Surrounding it with quotes like:

@"""C:\Users\user\Documents\test Video\video.wmv""" 

results with

The video file "C:\Users\user\Documents\test Video\video.wmv" does not exist.

I also tried without the "@":

"\"C:\\Users\\user\\Documents\\test Video\\video.wmv\""

but the result is the same.

Path.Combine("C:\\Users\\user\\Documents\\test Video\\video.wmv")
"\""+Path.Combine("C:\\Users\\user\\Documents\\test Video\\video.wmv")+"\""

also doesn't work. In the same time running the process form Windows Console like

ffmpeg.exe "C:\Users\user\Documents\test Video\video.wmv"

works totally fine.

UPDATE: The method uses the string like this:

public OutputPackage ConvertToFLV(string inputPath)
{
    VideoFile vf = null;
    try
    {
        //string path = string.Format("{0}", inputPath);
        vf = new VideoFile(inputPath);
    }
    catch (Exception ex)
    {
        throw ex;
    }

    OutputPackage oo = ConvertToFLV(vf);
    return oo;
}

and

In the video file class the exception is thrown here:

if (!File.Exists(_Path))
{
    throw new Exception("The video file " + _Path + " does not exist.");
}

Answer 1

It could be that converter.ConvertToFLV doesn't handle path names with spaces in them correctly. You can try giving it the 8.3 pathname which doesn't have spaces
