Question

我想做的是，我有以下xml：

邮政编码id =“E20 2AP”从=“test1”到=“test2”/＆gt;

我试图搜索邮政编码ID，然后从我的代码中获取来自该ID的文本：

    Public Shared Function GetFromDate(ByVal PostCode As String) As String
    Dim LoadToAddresses = From ex In doc.Descendants.Elements("Postcode") Select New With {.accountName = ex.Attribute("id").Value, .datefrom = ex.Attribute("from").Value}
    For Each x In LoadToAddresses
        Dim datefrom = (From p In LoadToAddresses Where p.accountName = PostCode Select New With {.datefrom = p.datefrom}).Single
        Return datefrom.ToString
    Next
End Function

这可行，但它会返回：

{datefrom = test}

我只想让它说“测试”

感谢

Answer 1

'Return datefrom.ToString
Return datefrom.datefrom

或：

'Dim datefrom = (From p In LoadToAddresses Where p.accountName = PostCode Select New With {.datefrom = p.datefrom}).Single
Dim datefrom = (From p In LoadToAddresses Where p.accountName = PostCode Select p.datefrom}).Single
