c# - How to find the file by its partial name?

Question

How can I get the full filename?

For example:

I have a file named 171_s.jpg that is stored on the hard disc.

I need to find the file by its partial name, i.e. 171_s, and get the full name.

How can I implement this?

Here's an example using GetFiles():

static void Main(string[] args)
{
    string partialName = "171_s";
    DirectoryInfo hdDirectoryInWhichToSearch = new DirectoryInfo(@"c:");
    FileInfo[] filesInDir = hdDirectoryInWhichToSearch.GetFiles("*" + partialName + "*.*");

    foreach (FileInfo foundFile in filesInDir)
    {
        string fullName = foundFile.FullName;
        Console.WriteLine(fullName);
    }    
}
