Question

I need to append a row from databla1 to datatable2 that has already rows, I tried to importrow(), clone(), but I cant' find the solution:

The datatable1 has this structure:

name | surname | iddepartment | address | phone1 | phone2 | country | cp | birthdate |

datatable2是在类中创建的公共数据表：

Public Shared datable2 As New DataTable

我有这段代码：

 Dim datatable1 As DataTable = getdata("myQuery")

我试图这样做，但是我收到了一个错误：

Dim newRow= datatable1.Rows(0)

myClass.datatable2.rows.add(newRow)

我该怎么做？感谢

据我了解。

VB.NET示例：

    'db query result'

    table.Columns.Add("Name", GetType(String))
    table.Columns.Add("surname", GetType(String))
    table.Columns.Add("iddepartment", GetType(Integer))
    table.Columns.Add("phone1", GetType(String))
    table.Columns.Add("phone2", GetType(String))
    table.Columns.Add("country", GetType(String))
    table.Columns.Add("cp", GetType(String))
    table.Columns.Add("birthdate", GetType(DateTime))

    'column set'
    Dim table2 As DataTable = table

    Dim i As Integer = 0

    'add dummy data'
    For index = 1 To 10
        'instance new dataRow '
        Dim dr As DataRow = table2.NewRow
        dr("Name") = "Jack"
        dr("surname") = "Daniels"
        dr("iddepartment") = i
        dr("phone1") = "099999"
        dr("phone2") = "09999"
        dr("country") = "USA"
        dr("cp") = "-"
        dr("birthdate") = New DateTime

        table2.Rows.Add(dr)

        i = i + 1
    Next

    'each table2 rows'
    For Each rowItem As DataRow In table2.Rows

        Console.WriteLine(rowItem("Name"))
        Console.WriteLine(rowItem("surname"))
        Console.WriteLine(rowItem("iddepartment"))
        Console.WriteLine(rowItem("phone1"))
        Console.WriteLine(rowItem("phone2"))
        Console.WriteLine(rowItem("country"))
        Console.WriteLine(rowItem("cp"))
        Console.WriteLine(rowItem("birthdate"))

    Next
    Console.Read()

如何从datatable1向带有寄存器ASP.NET的datatable2追加一行？
