求各位技术大神指导，开发的一个下东西上用到，百度上查也没见到解决办法，倒是好像有这样的说法
1.DataGridView 不能导入字符串，如果导入字符串需要封包？还是怎么地
2.查了好几天没见到这方面的解决办，如果有解决办法希望能和大家分享 excel c# DataGridView --------------------编程问答-------------------- 自己给自己顶个，是用来统计用的！所以是个小程序！
--------------------编程问答--------------------
检查下绑定表的字段类型和数量是否匹配
--------------------编程问答--------------------
难道就这原因！貌似没人出现过这样的问题？
求解 --------------------编程问答-------------------- 求代码，求解决！持续关注 --------------------编程问答-------------------- 最终解决代码！希望能帮助大家！
