Using SqlReader, when using reader.GetString(1) -OR- reader[“Details”], it only retrieves 4000 bytes of the string. How do I get the rest?

Question

I have instantiated an SqlDataReader, and when using reader.GetString(1) -OR- reader["Details"], it only retrieves the first 4000 characters of the string. How do I get the rest?

SqlCommand command = new SqlCommand(queryString, connection);
connection.Open();
SqlDataReader reader = command.ExecuteReader();
try
{
    while (reader.Read())
    {
        string foo = reader["Name"];
        string bar = reader.GetString(1);    //reader["Details"];
        // bar ONLY has the first 4000 bytes - not the entire field!
    }
}

Is the Details column in your database typed as text or ntext? If so, you need to use a method similar to that for blob data:

It's worth noting that TEXT and NTEXT are being deprecated. nvarchar and varchar are likely the types you are looking for.
