推荐答案

获取数据库表的值并将它们放入DataTable。



现在用你的字符串值检查DataTable行，列值在If条件下。

Took the value of the database table and put those into a DataTable.

Now check the DataTable row, column value with your string value in If condition.

If dt.Rows(0)(1).ToString() = "Your data" 
   //your code
Else
   // your code
End If
