在 WP7 中加载文本文件的 URI 是什么？

使用相对 uri 路径在 WP7 中显示任何图像非常简单。但加载文本文件就成了一个大问号。

请查看图像并尝试帮助 URI 应该如何将文件作为字符串变量。

Uri error

        Dim S As String
        Dim U As New Uri("file:///Family_christmas;component/database/de/1.txt", UriKind.Absolute)
        Dim sr As New IO.StreamReader(U.LocalPath, System.Text.Encoding.Unicode)
        S = sr.ReadToEnd
        sr.Close()
        Me.Title = S.Split(Environment.NewLine)(0)
        Me.Text = S.Substring(Me.Title.Length + Environment.NewLine.Length)

* 以此方式解决*

将文件声明为资源而不是内容。然后使用以下代码：

    Dim S As String
    Dim U As New Uri("database/de/1.txt", UriKind.Relative)
    Dim streamInfo As Windows.Resources.StreamResourceInfo = Application.GetResourceStream(U)
    Dim sr As New IO.StreamReader(streamInfo.Stream, System.Text.Encoding.Unicode)
    S = sr.ReadToEnd
    sr.Close()

It so simple to show any image in WP7 using relative uri path.
But loading a text file becomes a big questionmark.

Please look at the image and please try to help how the URI should looks like to have the file as string variable.

Uri error

        Dim S As String
        Dim U As New Uri("file:///Family_christmas;component/database/de/1.txt", UriKind.Absolute)
        Dim sr As New IO.StreamReader(U.LocalPath, System.Text.Encoding.Unicode)
        S = sr.ReadToEnd
        sr.Close()
        Me.Title = S.Split(Environment.NewLine)(0)
        Me.Text = S.Substring(Me.Title.Length + Environment.NewLine.Length)

* SOLVED THAT WAY *

Declare file as ressource not as content. Then use the following code:

    Dim S As String
    Dim U As New Uri("database/de/1.txt", UriKind.Relative)
    Dim streamInfo As Windows.Resources.StreamResourceInfo = Application.GetResourceStream(U)
    Dim sr As New IO.StreamReader(streamInfo.Stream, System.Text.Encoding.Unicode)
    S = sr.ReadToEnd
    sr.Close()

默认情况下，StreamReader 在文件系统中查找文件，而不是在资源中查找文件。您可以通过将您的文本文件标记为资源并使用以下代码来获取资源流：（抱歉将 vb 转换为 c# :)）

StreamResourceInfo info = Application.GetResourceStream(new Uri("file:///Family_christmas;component/database/de/1.txt", UriKind.Relative));
StreamReader reader = new StreamReader(info.Stream, System.Text.Encoding.Unicode);
string text = reader.ReadToEnd();
MessageBox.Show(text);

这对我有用。

By default StreamReader looks for the file in the file system, not in resources. You can get a resource stream my marking your text file as Resource and using this code: (sorry for the vb to c# conversion :))

StreamResourceInfo info = Application.GetResourceStream(new Uri("file:///Family_christmas;component/database/de/1.txt", UriKind.Relative));
StreamReader reader = new StreamReader(info.Stream, System.Text.Encoding.Unicode);
string text = reader.ReadToEnd();
MessageBox.Show(text);

This worked for me.
