Question

I’m using the following to read out values from my database:

    while (reader.Read())
    {
        newsLabel.Text += "<div style='float:left;'>" + reader["body"] + "</div>";
    }

I was wondering. How do I reduce the value of “body” to just 0,20 characters?

Is there a Substring function I can use?

Many thanks

You can do that as shown below. Make sure to check for DbNull.

while (reader.Read()) 
        {
            string body = reader["body"] is DBNull ? "" : Convert.ToString(reader["body"]);

            if(body.Length > 20)
              body = body .Substring(0, 20);

            newsLabel.Text += "<div style='float:left;'>" + body  + "</div>";   
        }
