推荐答案

在您的代码中，da是SqlDataAdapter.
但是daa是什么类型?您已使用daa = New SqlDataAdapter(qString, conn).尝试将daa更改为da.

检查qString是否为String和conn是否为SqlConnection.
如果这样做没有帮助，请在您的问题中添加更多详细信息.

In your code, da is SqlDataAdapter.
But what type daa is? You have used daa = New SqlDataAdapter(qString, conn). Try changing daa to da.

Check if qString is String and conn is SqlConnection.
If this doesn''t help, add more details to your question.
