c# 如何通过反射 获取\设置属性值、

public class MyClass
{
public int Property1 { get; set; }
}
static void Main()
{
MyClass tmp_Class = new MyClass();
tmp_Class.Property1 = 2;
Type type = tmp_Class.GetType(); //获取类型
System.Reflection.PropertyInfo propertyInfo = type.GetProperty("Property1"); //获取指定名称的属性
int value_Old = (int)propertyInfo.GetValue(tmp_Class, null); //获取属性值
Console.WriteLine(value_Old);
propertyInfo.SetValue(tmp_Class, 5, null); //给对应属性赋值
int value_New = (int)propertyInfo.GetValue(tmp_Class, null);
Console.WriteLine(value_New);

}
