想将所有表中增加两列，并赋值，但是出现错误，代码如下：For Each dt As DataTable In DataTables
Dim Names As New List (of String)
Names.add(dt.name)
For Each Name As String In Names
Output.Show (Name)
Next
Dim Builder As New ADOXBuilder
Builder.Open() '打开ADOXBuilder
With Builder.Tables(Name)
.AddColumn("LineName" ,ADOXType.String, 20) '增加字符列,长度为20
.AddColumn("Upload" ,ADOXType.Integer) '增加整数型列
End With
For Each dr As DataRow In DataTables(name).DataRows
dr("LineName" ) = "Line1"
dr("Upload" ) = "0"
Next
Builder.Close() '关闭ADOXBuilder
Next
