if you want to use the way what you currently used then you have implement be in below mentioned way

 var GetFileByFileName = Directory.GetFiles(@"D:\Re\reactdemo")
                                       .Select(x => new FileInfo(x))
                                       .Where(x => x.Name == "package.json")
                                       .Take(1)
                                       .ToArray();

check your SourcePath should look like what I have hard coded in code and your source file should be with extension
