c# - Environment.SpecialFolder 问题

Question

我将如何输入一个字符串来替换

(Environment.SpecialFolder.ApplicationData) 因为 .ApplicationData 部分需要根据传递给它的变量进行更改。

string specialFolder = ("Environment.SpecialFolder." + specialLocation);
specialLocation = "this will change depending on path location"; 
path = Path.Combine(Environment.GetFolderPath("specialFolder"),
                @""+backupPath);

希望我说得足够清楚了。

谢谢

Answer 1

使用 Enum.TryParse是你的答案

例如:

string s = "ApplicationData";
Environment.SpecialFolder sf;
if(Enum.TryParse<Environment.SpecialFolder>(s, true, out sf))
     Console.WriteLine(Environment.GetFolderPath(sf));

因此，您的代码可以写成:

Environment.SpecialFolder sf;
if(Enum.TryParse<Environment.SpecialFolder>(specialLocation, true, out sf))
{
    path = Path.Combine(Environment.GetFolderPath(sf), backupPath);
    .....
}
