Příklady

Následující příklad používá reflexi k získání vlastností DateTimeFormatInfo objektu pro jazykovou verzi angličtiny (Spojené státy). Zobrazí hodnotu těchto vlastností, které obsahují řetězce vlastního formátu, a používá tyto řetězce k zobrazení formátovaných kalendářních dat.

public class Example
{
   public static void Main()
   {
      // Get the properties of an en-US DateTimeFormatInfo object.
      DateTimeFormatInfo dtfi = CultureInfo.GetCultureInfo("en-US").DateTimeFormat;
      Type typ = dtfi.GetType();
      PropertyInfo[] props = typ.GetProperties();
      DateTime value = new DateTime(2012, 5, 28, 11, 35, 0);

      foreach (var prop in props) {
         // Is this a format pattern-related property?
         if (prop.Name.Contains("Pattern")) {
            string fmt = prop.GetValue(dtfi, null).ToString();
