Creating a File that the Path does not exists?

Question

I just can't get around this. I am able to create a file with File.Create... File.CreateText and so on but only if the path exists. If the path doesn't exist the file won't be written and returns an error.

How can I create the path?

Answer 1

Try

Directory.CreateDirectory(@"C:\MyApp\MySubDir\Data")

Answer 2

Given that you've the full path (Folder + File name), the following code will ensure your required directory path exists (if it does not exist already)

        FileInfo fileInfo = new FileInfo(fileFullPath);

        if (!fileInfo.Exists)
            Directory.CreateDirectory(fileInfo.Directory.FullName);


        //create the file ...

Answer 3

below should also work

    FileInfo fileInfo = new FileInfo(fileFullPath);
    if (!fileInfo.Directory.Exists) fileInfo.Directory.Create()

work on directory of fileinfo, rather than static directory class

Answer 4

You will need to create the Directory first. It will create all of the subdirectories that don't exist within the path you send it. It's quite a powerful piece of functionality.

Directory.CreateDirectory(filePath);

If you don't know whether the directory exists or not you can use Directory.Exists. But not for this case as it would be pointless. MSDN states that CreateDirectory does nothing if the directory currently exists. But if you wanted to check existance of the directory for another reason you can use:

  if(Directory.Exists(folder) == false)
    {
    //do stuff  
    }
