}
if(this.RBS.Checked==true)

3 student.Gender =Gender ;

if(StudentServices1.AddStudent(student)>0)
{
MessageBox .Show("添加学生信息成功！");
}
else

return ;
}

}

}
}

Answer 1

错误原因可能有2种:

1. string Grender = null;拼写错误,应该为:

   string Gender = null;

   
   

2. Gender=this.RBS.Text;应该为:

   this.Gender.Text = this.RBS.Text;

Answer 2

哪一句报错。应该是你直接把string的值 赋给Label类型了
应该是Label的 Gender.Text = this.RBS.Text;

Answer 3

变量的名称有误，这是比较常见的错误，错误提示也不怎么靠谱的说

Answer 4

你的RBF
是什么控件的名字？ lable？

按常理，你的RBF应该为单选框radiobutton，

Answer 5

你下次发文时可不可以先学会清楚的表达你要陈述的内容！
