How to load from relative path in WPF application?
提问by Edward Tanguay
I'm reading an xml file and want to make it from a relative directory based on the location of the application, similar to ASP.NET with Server.MapPath or using the tilda.
我正在读取一个 xml 文件，并希望根据应用程序的位置从相对目录中创建它，类似于带有 Server.MapPath 的 ASP.NET 或使用 tilda。
How can you get the relative path in WPF?
如何获得WPF中的相对路径？
WORKS: XDocument xmlDoc = XDocument.Load(@"c:\testdata\customers.xml");
DOES NOT WORK: XDocument xmlDoc = XDocument.Load(@"~\Data\customers.xml");
DOES NOT WORK: XDocument xmlDoc = XDocument.Load(@"~/Data/customers.xml");
采纳答案by Kent Boogaart
XDocument xmlDoc = XDocument.Load(@"Data\customers.xml");
OR
或者
XDocument xmlDoc = XDocument.Load(@".\Data\customers.xml");
BTW, this has nothing to do with WPF and everything to do with Windows paths.
顺便说一句，这与 WPF 无关，而与 Windows 路径无关。

XDocument xmlDoc = XDocument.Load(
Path.Combine(
AppDomain.CurrentDomain.BaseDirectory,
@"Data\customers.xml"));
I assume the Datadirectory is going to get deployed with your app, in the same root directory as your EXE. This is generally safe, except where shadow copying is involved; for example, when you use NUnit to test this code. (With shadow copying, the assemblies that make up your app get copied to a temporary directory, but files like this get left behind.)
我假设该Data目录将与您的应用程序一起部署在与您的 EXE 相同的根目录中。这通常是安全的，除非涉及卷影复制；例如，当您使用 NUnit 测试此代码时。（通过影子复制，构成应用程序的程序集会被复制到一个临时目录，但这样的文件会被留下。）
Assuming you're not planning to modify customers.xmlafter deployment, the safest way to handle this is to embed the file as a resource within your assembly.
假设您不打算customers.xml在部署后进行修改，最安全的处理方法是将文件作为资源嵌入到程序集中。

Try File.Create("./HiImHere.txt")to see where is the point directory; after that try the path relative to where HiImHere.txtis.
试试看File.Create("./HiImHere.txt")点目录在哪里；之后尝试相对于 where 的路径HiImHere.txt。
