What are you wanting to export via a text file? In general, you can use the RasterCodecs Save method to export and save your results. The Save method allows you to export to a text file among other file types. You can try building on the following code for this.
using (RasterCodecs codecs = new RasterCodecs())
{
    Android.Net.Uri uri = data.Data;
    Stream stream = ContentResolver.OpenInputStream(uri);
    RasterImage image = codecs.Load(stream);
    codecs.Save(image, stream, RasterImageFormat.Txt, 0);
}

Greetings:
try this
string path=Environment.GetFolderPath(Environment.ExternalStorageDirectory);
string filename=Path.Combine(path,"myfile.txt");
using(var streamWriter=new StreamWriter(filename,true))
{
streamWriter.WriteLine(DateTime.UtcNow);
}
using(var streamReader=new StreamReader(filename))
{
string content=streamReader.ReadToEnd();
System.Diagnostics.Debug.WriteLine(content);
}
