用C#如何在Windows应用程序中创建类

private string_no;
private int_age;
private string_grade;
public string StudentNo
{
get{return_no;}
set{_no=value;}
}
public int StudentAge
{
get{return_age;}
set{_age=value;}
}
public string StudentGrade
{
get{return_grade;}
set{_grade=value;}

显示标记无效 = =|||
如何是好

Answer 1

少了必须的空格间隔了吧.
像return后面和变量间需要空格或其它间隔符.
变量声明也是一样的问题.

Answer 2

private string _no;
private int _age;
private string _grade;

public string StudentNo
{
get{return _no;}
set{_no=value;}
}
public int StudentAge
{
get{return _age;}
set{_age=value;}
}
public string StudentGrade
{
get { return _grade; }
set { _grade = value; }
}
