System.Reflection - FieldInfo class

A FieldInfo class provides detailed information about a single field of a class or an interface. The reflected field may be a static field or an instance field. The FieldInfoSpy example shows how to obtain the field information of a class including the access modifiers, type etc:

 

using System;
using System.Reflection;

namespace ConsoleApplication1
{
internal class FieldInfoSpy
{
private static void Main(string[] args)
{
    Type type = typeof (Car);

    //query type 
    FieldInfo[] fieldInfos = type.GetFields(
        //Specifies that instance members are to be included in the search. 
        BindingFlags.Instance |
        //Specifies that non-public members are to be included in the search. 
        BindingFlags.NonPublic |
        //Specifies that public members are to be included in the search. 
        BindingFlags.Public |
        //Specifies that static members are to be included in the search. 
        BindingFlags.Static); 


    foreach (FieldInfo fieldInfo in fieldInfos)
    {
        Console.WriteLine(
            "Name:{0},Type:{1},Public:{2},Static:{3},Readonly:{4}",
                          fieldInfo.Name,
                          fieldInfo.FieldType.FullName,
                          fieldInfo.IsPublic,
                          fieldInfo.IsStatic,
                          fieldInfo.IsInitOnly
            );
    }

    Console.ReadLine();
}
}

internal class Car
{
public bool broken;
private static string vendor;
public readonly string owner;
private int age;
protected string name;
}
}

A sample of the output follows:

Name:broken,Type:System.Boolean,Public:True,Static:False,Readonly:False
Name:owner,Type:System.String,Public:True,Static:False,Readonly:True
Name:age,Type:System.Int32,Public:False,Static:False,Readonly:False
Name:name,Type:System.String,Public:False,Static:False,Readonly:False
Name:vendor,Type:System.String,Public:False,Static:True,Readonly:False
