推荐答案

我建议使用System.IO.Path.GetTempPath()，因为这将始终为您提供任何给定系统的有效路径.

I recommend using System.IO.Path.GetTempPath() as this will always give you a valid path for any given system.

此外，对于给定的实例，函数可能会同时执行多次，因此最好确保每次执行都有唯一的路径.这是一个简单的示例:

Additionally, functions may execute multiple times simultaneously for a given instance, so it's best to ensure you have a unique path for each execution. Here's a simple example:

var tempPath = Path.Combine(Path.GetTempPath(), Guid.NewGuid().ToString());
