Me having a local xml file and need to load it to Isolated Storage when my app. starts for first time. but if i am opening that file using stream OR File.Open it's throwing an error. Also i need to store that file in serialized form. Please help, as being new to WP7 and C# not able to crack it.

以下代码用于打开 XML 文件:

Following code is used for opening the XML file:

FileStream stream = new FileStream("site.xml", FileMode.Open);

推荐答案

如果该文件是您项目的一部分，那么您可以将该文件作为资源添加到您的项目中.这意味着文件的 "Build Action" 应该是 "Resource".下面的函数可以从项目资源中读取文件.

If the file is a part of your project then you can add the file to your project as resource. That means file "Build Action" of the file should be "Resource". And the following function can read the file from project resource.

Stream stream = this.GetType().Assembly.GetManifestResourceStream("Namespace.FileName.FileExtentation");

现在您可以根据文件类型读取流.如果它是一个 XML 文件，那么您可以像下面一样阅读它.

Now you can read the stream according to the file type. If it is a XML file then you can read it like below.

举个例子

XElement element = XElement.Load(stream);
foreach (XElement phraseElement in element.Elements())
{
    MyClass foo = new foo();
    foreach (XAttribute attribute in phraseElement.Attributes())
      foo.Text = attribute.Value;

}
