read()函数在读取时，如何把读入的信息重新赋值到 Stu方法中定义的this.age,this.name变量中， 读入的文件内容如下
姓名:admin
年龄:10
性别:man
学号:110
语文:100
数学:100
英语:100

求解决，求高手 c# --------------------编程问答-------------------- 根据读到的信息进行字符串和类型转换的操作
你用xml或者数据库都比较好过文本文件 --------------------编程问答-------------------- 每一行前面不是都有说明是哪一科吗，解析出后面的数字，直接写到结构体对应的属性就行了，不过你这种存储只能一条条写if语句去赋值，你应该用流结合struct整体读入 --------------------编程问答--------------------
小弟 新手比较菜唉

小弟新手比较菜唉，我就想修改一个read()函数
--------------------编程问答--------------------
目前还没有学数据库
补充：.NET技术 , C#
