存在行，但是错误“在位置(0)没有行". [英] Row exists but error "there is no row at position(0)"

问题描述

亲爱的朋友，

我的程序中有以下代码块-

Dear friends,

I have the following code block in my program-

dim RowPostion as integer 
If dt.Rows.Count > 0 Then
  MsgBox(dt.Rows(RowPostion)(0).ToString) 
  MsgBox(dt.Rows(RowPostion )(1).ToString) 
  dt.Rows.RemoveAt(RowPostion) 
End If

问题是，我能够读取值，但无法删除.尝试删除该行时，它返回"position(..)没有行".


我找不到任何解决方法.
关于这个问题，您能帮我吗?

SKPaul.

I cound not find any solution.
Would you please help me regarding this issue?

推荐答案

我希望问题是因为您没有为行位置指定起始值

试试这个

I hope the problem is because you didn''t specified a starting value for the row position

try this

Dim RowPosition as integer = 0
If dt.Rows.Count > 0 Then
  MsgBox(dt.Rows(RowPostion)(0).ToString)
  MsgBox(dt.Rows(RowPostion )(1).ToString)
  dt.Rows.RemoveAt(RowPostion)
End If

(如果RowPosition以1开头，请首先检查数据行计数和Row位置的值，然后尝试将Row位置的值退回到其原始位置)

(First check the value of data row count and Row position then try to set the value of Row position one step back to its original position, if the RowPosition is starting with 1)
