红色子图部分为报错部分，两个地方的错误相同，错误提示如下，绿色字体可以直接忽略
-----------------------------------------------------------------------------------------------------------------------------------------
错误 1 与“xxx.ILinarList<xxx.SNode<xxx.Stu_Node>>.InsertNode_End(xxx.SNode<xxx.Stu_Node>)”最匹配的重载方法具有一些无效参数
错误 2 参数 1: 无法从“xxx.Stu_Node”转换为“xxx.SNode<xxx.Stu_Node>”
-----------------------------------------------------------------------------------------------------------------------------------------
求解...
