You can get the list files that contain test in their name:

var files = Directory.EnumerateFiles(folderPath, "*test*.*");

Also you can use regex to do this:

Regex reg = new Regex(@".*test.*\..*",RegexOptions.IgnoreCase);

var files = Directory.GetFiles(yourPath, "*.*")
                     .Where(path => reg.IsMatch(path))
                     .ToList();

System.IO.DirectoryInfo dir = new System.IO.DirectoryInfo(folderPathToUploadedFiles);

IEnumerable<System.IO.FileInfo> fileList = dir.GetFiles("*.*", System.IO.SearchOption.AllDirectories);

IEnumerable<System.IO.FileInfo> fullfileinfo =(from file in fileList  where file.Name.Contains("test") select file);

This will get you a list of matching files, and then move each one:

foreach (var file in Directory.EnumerateFiles("somePath", "test_*"))
{
    var newFileName = Path.GetFileName(file).Remove(0, 5);  // removes "test_"

    File.Move(file, Path.Combine(Path.GetDirectoryName(file), newFileName));
}

this code renames all files with the keyword "test_". it is NOT case sensitive due to the "ToLower()" call

        const string testKeyword = "test_";
        var testFilePaths = Directory.GetFiles(@"c:\tmp").Where(f => f.ToLower().Contains(testKeyword.ToLower()));
        foreach (var testFilePath in testFilePaths)
        {
            File.Move(testFilePath, testFilePath.Replace(testKeyword, string.Empty));
        }
