below code should work:
下面的代码应该工作：
string path = Path.Combine(Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location), @"Data\Names.txt");
string[] files = File.ReadAllLines(path);
回答by Massimiliano Peluso
it depends where is your Data folder
这取决于您的数据文件夹在哪里
To get the directory where the .exe file is:
要获取 .exe 文件所在的目录：
AppDomain.CurrentDomain.BaseDirectory
To get the current directory:
获取当前目录：
Environment.CurrentDirectory
Then you can concatenate your directory path (@"\Data\Names.txt")
然后你可以连接你的目录路径 ( @"\Data\Names.txt")

If you need to get all the files in the folder named 'Data', just code it as below
如果您需要获取名为“Data”的文件夹中的所有文件，只需将其编码如下
string[] Documents = System.IO.Directory.GetFiles("../../Data/");
Now the 'Documents' consists of array of complete object name of two text files in the 'Data' folder 'Data'.
现在，“文档”由“数据”文件夹“数据”中两个文本文件的完整对象名称数组组成。

For Xamarin.iOS you can use the following code to get contents of the file if file exists.
对于 Xamarin.iOS，如果文件存在，您可以使用以下代码获取文件的内容。
var documents = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);
var filename = Path.Combine(documents, "xyz.json");
if (File.Exists(filename))
{
var text =System.IO.File.ReadAllText(filename);
}
