使用反射來查找ArrayList對象屬性

Question

我所擁有的是對象的ArrayList，我試圖使用反射來獲取ArrayList中每個對象的每個屬性的名稱。例如：

private class TestClass 
{ 
    private int m_IntProp; 

    private string m_StrProp; 
    public string StrProp 
    { 
     get 
     { 
      return m_StrProp; 
     } 

     set 
     { 
      m_StrProp = value; 
     } 
    } 

    public int IntProp 
    { 
     get 
     { 
      return m_IntProp; 
     } 

     set 
     { 
      m_IntProp = value; 
     } 
    } 
} 

ArrayList al = new ArrayList(); 
TestClass tc1 = new TestClass(); 
TestClass tc2 = new TestClass(); 
tc1.IntProp = 5; 
tc1.StrProp = "Test 1"; 
tc2.IntProp = 10; 
tc2.StrPRop = "Test 2"; 
al.Add(tc1); 
al.Add(tc2); 

foreach (object obj in al) 
{ 
    // Here is where I need help 
    // I need to be able to read the properties 
    // StrProp and IntProp. Keep in mind that 
    // this ArrayList may not always contain 
    // TestClass objects. It can be any object, 
    // which is why I think I need to use reflection. 
}
