您如何转换驱动器的相对路径，如D：的test.xml成一个函数，如XDocument.Load（）将接受一个绝对路径。 D盘可能有D：\数据作为其当前工作目录，例如，所以D：的test.xml意味着D：\数据\的test.xml。我已经尝试过这样的调酒为D：\的test.xml

How can you convert a drive relative path such as D:test.xml into an absolute path that a function such as XDocument.Load() will accept. The D drive could have D:\data as its current working directory, for example, so D:test.xml would mean D:\data\test.xml . I've already tried such concoctions as D:.\test.xml .

下面是错误，我得到的东西，如D：的test.xml：无效的URI：一个DOS路径必须扎根，例如C：\

Here is the error I get for something like D:test.xml: Invalid URI: A Dos path must be rooted, for example, 'c:\'

推荐答案

您可以使用的 GetFullPath 。例如：

You could use GetFullPath. For example:

// should return "D:\data\test.xml" if the current working dir is "D:\data"
string absolutePath = Path.GetFullPath("D:test.xml");
