How to check existence of directory using path C#

Question

Using

Directory _dir = Directory.CreateDirectory(path);

So how to store the object of directory in a variable so then I have to check whether the directory at specified path exists or not as?

if(!_dir.exists())
{
    _dir.CreateDirectory(path);
}

Is it allowed in C#?

Directory.CreateDirectory will actually check if the directory exists before attempting to create it, so there's really no reason to check if it exists before calling it. However you can always use the DirectoryInfo class, which Directory.CreateDirectory returns, to do what you want. — juharr

Just fyi you will always have a race condition when writing IO code like that - be ready to catch the exogenous IO exception. blogs.msdn.microsoft.com/ericlippert/2008/09/10/… — asawyer

@juharr it means there is no need to check whether directory exists or not because CreateDirecotory() automatically checks this. Thanks — maliks

"Is it allowed in C#?" the correct way it would be "if (!System.IO.Directory.Exists(path)) { System.IO.Directory.CreateDirectory(path); }" but as @juharr mentioned, CreateDirectory already verify if it exists — awdk

Try This...

        string path=@"C:\Users\v\Desktop\DESKTOP";
        if(!Directory.Exists(path))
        {
            Directory.CreateDirectory(path);
        }

DirectoryInfo dir = Directory.CreateDirectory(path);
if(!dir.Exists)
{
    dir.CreateDirectory(path);
}

Or

DirectoryInfo dir = Directory.CreateDirectory(path);
if(!Directory.Exists(path))
{
    dir.CreateDirectory(path);
}
