FileOpenPicker -如何读取特殊字符

Question

我对FileOpenPicker有意见。我使用特殊字符，例如śćę和我的文件śćę的内容：“śśććęó”

这是我的密码：

var picker = new Windows.Storage.Pickers.FileOpenPicker();
picker.ViewMode = Windows.Storage.Pickers.PickerViewMode.List;
picker.SuggestedStartLocation = Windows.Storage.Pickers.PickerLocationId.Desktop;
picker.FileTypeFilter.Add(".txt");

Windows.Storage.StorageFile file = await picker.PickSingleFileAsync();
if (file != null)
{
    using (var inputStream = await file.OpenReadAsync())
    using (var classicStream = inputStream.AsStreamForRead())
    using (var streamReader = new StreamReader(classicStream))
    {
        var something = streamReader.ReadToEnd();
    }
}

当我读到我的档案时，我得到了这样的信息：

我试过改变文化编码什么的都没有。

这门课有什么问题？

我真的很感激在这方面的任何帮助或指导。谢谢!

问题不在于类，而在于txt文件的编码。您可能已经将编码设置为ANSI，如果您尝试用代码读取它，它将给您带来奇怪的字符。要正确地执行此操作，您必须定义特定的编码以及注册提供程序：

var picker = new Windows.Storage.Pickers.FileOpenPicker();
picker.ViewMode = Windows.Storage.Pickers.PickerViewMode.List;
picker.SuggestedStartLocation = Windows.Storage.Pickers.PickerLocationId.Desktop;
picker.FileTypeFilter.Add(".txt");
Windows.Storage.StorageFile file = await picker.PickSingleFileAsync();
if (file != null)
{
    // register provider - by default encoding is not supported
    Encoding.RegisterProvider(System.Text.CodePagesEncodingProvider.Instance);
    using (var inputStream = await file.OpenReadAsync())
    using (var classicStream = inputStream.AsStreamForRead())
    using (var streamReader = new StreamReader(classicStream, Encoding.GetEncoding(1250)))
    {
        var something = streamReader.ReadToEnd();
    }
}

如果您用UTF-8编码保存了您的文件，那么您就可以立即读取它，这样就容易多了。
