Description
This enumeration is used by reflection classes such as Binder, Module, and ConstructorInfo. BindingFlags values are used to control binding in methods in classes that find and invoke, create, get, and set members and types.
To specify multiple BindingFlags values, use the bitwise "OR" operator.
Example
using System;
using System.Reflection;
/// <summary>
/// This example shows the varoius ways of using BindingFlags.
/// First we should al the members of object, then we invoke a
/// method off of System.String. Then we invoke a property off
/// string.
/// </summary>
public class BindingFlagsSample
{
public static void Main()
{
Console.WriteLine("Public Members: DeclaredOnly");
foreach (MemberInfo m in typeof(Int32).GetMembers(
BindingFlags.Instance | BindingFlags.Static |
BindingFlags.Public | BindingFlags.DeclaredOnly))
{
Console.WriteLine(" {0}",m.Name);
}
Console.WriteLine("Public Members: FlattenHierarchy");
foreach (MemberInfo m in typeof(Int32).GetMembers(
BindingFlags.Instance | BindingFlags.Static |
BindingFlags.Public | BindingFlags.FlattenHierarchy))
{
Console.WriteLine(" {0}", m.Name);
}
Console.WriteLine("Protected and Private Members: FlattenHierarchy");
foreach (MemberInfo m in typeof(Int32).GetMembers(
BindingFlags.Instance | BindingFlags.Static |
BindingFlags.NonPublic | BindingFlags.FlattenHierarchy))
{
Console.WriteLine(" {0}", m.Name);
}
string s = "Life, The Universe, and Everything ";
Type type = typeof(String);
int length;
//Latebound equivalent to: s = s.Remove(0,6);
s = (string) type.InvokeMember ("Remove",BindingFlags.InvokeMethod,
null, s, new Object [] {0,6});
//Latebound equivalent to: length = s.Length;
length = (int)type.InvokeMember("Length", BindingFlags.GetProperty,
null, s, null);
Console.WriteLine("'{0}'", s);
Console.WriteLine("Length = {0}", length);
