Answer 1

StringReader is a TextReader (StreamReader is too, but for reading from streams). So taking your first example and just using it to construct the CsvReader rather than trying to construct a StreamReader from it first gives:

TextReader sr = new StringReader(TextBox_StartData.Text);
using(CsvReader csv = new CsvReader(sr, true))
{
  DetailsView1.DataSource = csv;
  DetailsView1.DataBind();
}

Answer 2

Use System.IO.StringReader :

using(TextReader sr = new StringReader(yourstring))
{
    DoSomethingWithATextReader(sr);
}

You want a StringReader

var val = "test string";
var textReader = new StringReader(val);

Answer 4

Simply use the StringReader class. It inherits from TextReader.

If you look at the documentation for TextReader, you will see two inheriting classes. And one of them is StringReader, which seems to do exactly what you want.

Answer 6

Use the StringReader class, which inherits TextReader.
