You can use a custom extension method as shown below:

/// 

/// Returns only the first n characters of a String.
/// 
/// 
/// 
/// 
/// 
public static string TruncateString(this string str, int start, int maxLength)
{        
    return str.Substring(start, Math.Min(str.Length, maxLength));
}

Hope this helps...
