Question

我想发送一个文本文件和我的应用程序，并在执行我的应用程序时读取它。我该如何阅读该特定文件？我已将文件设置为内容并在较新时复制。

Answer 1

private async void ProjectFile()
{
    var _Path = @"Metro.Helpers.Tests\MyFolder\MyFolder.txt";
    var _Folder = Windows.ApplicationModel.Package.Current.InstalledLocation;

    var _File = await _Folder.GetFileAsync(_Path);
    var _ReadThis = await Windows.Storage.FileIO.ReadTextAsync(_File);
}

读取适合我的项目文件的代码。希望它也有助于其他人：）

您的问题的答案在很大程度上取决于您想要阅读文件的以及它包含的内容。

您可以在File Access Sample app on MSDN中找到一些文件访问示例，其中一个示例是：

if (file != null) 
{ 
    using (IRandomAccessStream readStream = await file.OpenAsync(FileAccessMode.Read)) 
    { 
        using (DataReader dataReader = new DataReader(readStream)) 
        { 
            UInt64 size = readStream.Size; 
            if (size <= UInt32.MaxValue) 
            { 
                UInt32 numBytesLoaded = await dataReader.LoadAsync((UInt32)size); 
                string fileContent = dataReader.ReadString(numBytesLoaded); 
                OutputTextBlock.Text = "The following text was read from '" + file.Name + "' using a stream:" + Environment.NewLine + Environment.NewLine + fileContent; 
            } 
            else 
            { 
                OutputTextBlock.Text = "File " + file.Name + " is too big for LoadAsync to load in a single chunk. Files larger than 4GB need to be broken into multiple chunks to be loaded by LoadAsync."; 
            } 
        } 
    } 
}
