How to create appdata folder with C#
提问by Matthew H
Well, I don't know how to type all this so bear with me please.
好吧，我不知道如何输入所有这些，请耐心等待。
This is beyond me, I'm still a newb at C#. I basically need to create a folder in the roaming application data of the current user running the program. I also need to access another folder in the application data section and then replace a file with a copy of the file in the application data folder I had created.
这超出了我的范围，我仍然是 C# 的新手。我基本上需要在运行该程序的当前用户的漫游应用程序数据中创建一个文件夹。我还需要访问应用程序数据部分中的另一个文件夹，然后用我创建的应用程序数据文件夹中的文件副本替换文件。

The first two passes are straightforward
前两个pass很简单
// The folder for the roaming current user
string folder = Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData);
// Combine the base folder with your specific folder....
string specificFolder = Path.Combine(folder, "YourSpecificFolder");
// CreateDirectory will check if folder exists and, if not, create it.
// If folder exists then CreateDirectory will do nothing.
Directory.CreateDirectory(specificFolder);
In the last pass is not clear where you have the file to copy.
However, supposing that you have a file called
在最后一遍中不清楚您要将文件复制到何处。
但是，假设您有一个名为
string file = @"C:\program files\myapp\file.txt";
File.Copy(file, Path.Combine(specificFolder, Path.GetFileName(file));

I would suggest you to use Isolated Storagewithout bothering where your files are physically located. That's more flexible way - you just use the Isolated Storage API and the .NET framework is responsible where physically files are located (for example in different operating systems location may be different).
我建议您使用独立存储，而不必担心文件的物理位置。这是更灵活的方式 - 您只需使用隔离存储 API，而 .NET 框架负责物理文件所在的位置（例如在不同的操作系统中位置可能不同）。
