C# 批量插入时的InvalidOperationException

我有一个.Net应用程序，用户可以上传格式化的csv文件。程序解析这些值，然后将它们上传到我们的数据库

问题是，最初的程序员为每一行数据创建了一个循环和一个sql insert语句。在一些较大的csv文件上，这可能需要几个小时

我决定通过将数据放入datatable并进行批量更新来解决这个问题。我遇到的问题是在我的

.WriteToServer

行上出现

无效操作异常

这是我的密码

异常是否包含任何有用的信息？不幸的是，System.Data.dll中没有发生类型为“System.InvalidOperationException”的异常，但未在用户代码中处理。请尝试捕获大容量复制代码，并用异常更新您的问题。因此。。。这很奇怪。我照你说的做了，结果我的计划成功了。数据已成功放入我的数据库。您所做的只是将“重试捕获”放在它周围？你走过去了吗？
