C#通过反射获取按钮的文本

string text = "";
//加载程序集
Assembly assembly = Assembly.LoadFrom(Directory.GetCurrentDirectory() + "//WindowsApplication3.exe");
//创建实例
object obj=assembly.CreateInstance("WindowsApplication3.Form2");
//获取实例对象类型
Type form = obj.GetType();
//获取类型中的所有字段
FieldInfo[] fis = form.GetFields(BindingFlags.NonPublic | BindingFlags.Public | BindingFlags.Instance);
foreach (FieldInfo fi in fis)
{
if (fi.FieldType == typeof(Button))//判断字段是否为按钮
{
text += fi.Name+"/r/n----------------------------------/r/n";
//获取按钮的实例的类型
Type bt = (fi.GetValue(obj)).GetType();
//获取按钮实例的所有属性
PropertyInfo[] pis=bt.GetProperties(BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.Instance);
foreach (PropertyInfo pi in pis)
{
if(pi.Name=="Text")//判断该属性是否为Text
{
text += pi.GetValue((fi.GetValue(obj)), null) + "/r/n";
}
}
text += "-----------------------------------------/r/n";
}
}
textBox1.Text = text;
