Answer 1

Verwenden Sie die Zeichenfolge 'new line character' "\ n", um neue Zeilen zu erstellen. Wie folgt aus:

textBox1.Text = reader["Name"].ToString() + "\n"; 
textBox20.Text = reader["Description"].ToString() + "\n"; 

Answer 2

dies versuchen,

textBox1.Multiline = true; 
textBox1.ScrollBars = ScrollBars.Vertical;//Other settings is Horizontal and Both 
textBox1.AcceptsReturn = true; 
textBox1.WordWrap = true; 

textBox20.Multiline = true; 
textBox20.ScrollBars = ScrollBars.Vertical;//Other settings is Horizontal and Both 
textBox20.AcceptsReturn = true; 
textBox20.WordWrap = true; 

while (reader.Read()) 
{ 
    textBox1.Text += reader["Name"].ToString() + Environment.NewLine; 
    textBox20.Text += reader["Description"].ToString() + Environment.NewLine; 
}
