获取文件的相对路径？

Question

I have a file called settings.xml located at:

c:\\solution1\\solution1\\data\\settings.xml

Right now, I am doing:

XDocument doc = XDocument.Load(@"c:\solution1\solution1\settings.xml");

I can't figure how to do it with a relative path.

Answer 1

If you mean relative to your executable, you can use

string exeLocation = System.Reflection.Assembly.GetExecutingAssembly().CodeBase

Note the frequently suggested

System.Reflection.Assembly.GetExecutingAssembly().Location

will get the path where the assembly is currently located , which can be different eg if a shadow copy is being executed.

You can use

string exeDir = System.IO.Path.GetDirectoryName(exeLocation);

to get the executable's directory.

If you want to find a file that is in a data directory under your install location, you could do

string dataFile = Path.Combine(exeDir, "data\settings.xml");

Note that under Windows Vista and later, you will not have write access by default to a directory located under your install directory.

Answer 2

您还可以相对于它从其开始的当前目录

System.Environment.CurrentDirectory
