DataView循环和编辑？ [英] DataView loop and edit?
问题描述
亲爱的朋友
将myDataView调暗为DataView = New DataView（dsData.Tables（" tblCustomers"））
myDataView.RowFilter =" City =''London''"
我的问题是如何遍历myDataView中的所有行并编辑字段
fldZipCode so fldZipCode =" 9800"

这很好
我的整数= 0到myDataView.count - 1
MsgBox（myDataView（i）（fldZipCode））

但这会导致超出范围错误
For i as Integer = 0 to myDataView.count - 1
myDataView（i）（" fldZipCode"）=" 9800"
Next

This goes fine
For i as Integer = 0 to myDataView.count - 1
MsgBox(myDataView(i)("fldZipCode"))
Next
but this causes out of range error
For i as Integer = 0 to myDataView.count - 1
myDataView(i)("fldZipCode")="9800"
Next

此示例使用数据视图dv。
Dim drv As DataRowView
For each drv in dv
drv.BeginEdit（）
drv.Item（" PostalCode" ;）=" 2345"
drv.EndEdit（）
