DataGridView 未刷新

问：

我的脚本有问题。我有一个 DataGridView，我想将每个 import-csv 的数据插入到变量中，当我尝试刷新它显示插入数据的 DataGridView 时，它什么也没做。$DataGridView.DataSource

这是完整的脚本（如果你想自己重现它）（尝试刷新它的部分用#突出显示）：

如果您想知道这里是 CSV：

"Customer","Problem","Solution","Email","Phone","ID"
"this","is","a ","wonderful","functioning","test"

如果有人知道任何可以解决我不显示数据的问题的方面，我将不胜感激。
