Answer 1

如何遍歷不同組 - 行的數據表：

Dim i as Integer = 0 
Dim row as DataRow 
For Each row in myDataTable 
    If (condition) Then 
    'do something 
    Else 
    'something else 
    End If 
    'in case you need to keep a counter 
    i = i + 1 
End 

Answer 2

我不是100％肯定我的理解;但我認爲...... 您將無法使用對於每個訪問行並修改集合。

最明確的方法是使用While循環。

Dim i as Integer = 0 
While i < myDataTable.Rows.Count 
    ' Your If statement here 
End While
