问题是：
set
{
_name=value;
}
未处理的“stytem.stackoverflowexception”类型的异常出现在teacher.exe中。teacher是我文件的名字。
本人大一，求高手指导。黄色的条状出现在第一个“{”

改成这样，有你那样写的嘛。。。

      //属性
        public string _name
        {
            get
            {
                return name;
            }
            set
            {
                name = value;
            }
        }
        public string _sex
        {
            get { return sex; }
            set { sex = value; }
        }
        public string _age
        {
            get { return age; }
            set { age = value; }
        }

当然，属性不能调用属性，否则引起无限递归。

你要明白属性的原理：

set
{
_name=value;
}
相当于
void set__name(string value)
{
set__name(value); // 自身调用自身
}

真够乱的，
public string _name
{
get
{
return _name;
}
set
{
_name = name;
}
}

改成：


public string Name { get; set; }

get
{
return name;
}
set

还有个问题
就是这个喜欢的科目

怎么出现的是a,1,1,11.....
是不是我这里写错了
public void show(string yuwen)
{
MessageBox.Show(name+","+sex+","+age+","+"喜欢的科目"+yuwen);
}
