首先是获取一个对象中成员变量的值

public class Program
        {
            public string str = "spp";
            public string spp = "Hello World!";
    
            public static void Main(string[] args)
            {
                Program p = new Program();
    
                Console.WriteLine(p.GetType().GetField(p.str).GetValue(p).ToString());
                Console.ReadKey();
            }
        }

获取并修改静态变量的值

//动态链接库中ClsPublic类有一变量 private static string key="1111";	//下面通过反射的技术修改和获取值	//设置key        
     public static void updatePalmKey(string key = "test")
            {
                BindingFlags flag = BindingFlags.Static | BindingFlags.NonPublic;
                FieldInfo f_key = typeof(ClsPublic).GetField("key", flag);
                f_key.SetValue(new ClsPublic(), key);
            }
    
            /// <summary>
            /// 获取key
            /// </summary>
            /// <returns></returns>
            public static string getPalmKey()
            {
                BindingFlags flag = BindingFlags.Static | BindingFlags.NonPublic;
                FieldInfo f_key = typeof(ClsPublic).GetField("key", flag);
                object o = f_key.GetValue(new ClsPublic());
                return o.ToString();
            }	
    	//反射获取修改类中的属性	
    	class Test	
    	{		
    	public string StrTest {get; set;};	
    	}        
    	/// <summary>
            /// 获取修改类中的属性
            /// </summary>
            /// <returns></returns>
            public void GetAndSetProperty()
            {		Test t = new Test();
    		PropertyInfo p=t.GetType().GetProperty("StrTest");
                    	p.SetValue(p,"test");
            }
    
            /// <summary>
            /// 获取key
            /// </summary>
            /// <returns></returns>
            public static string getPalmKey()
            {
                BindingFlags flag = BindingFlags.Static | BindingFlags.NonPublic;
                FieldInfo f_key = typeof(ClsPublic).GetField("key", flag);
                object o = f_key.GetValue(new ClsPublic());
                return o.ToString();
            }
