Dim Arys As List(Of String())

Dim str,str1 As String

Arys = Tables("主表.主表明细").DataTable.GetValues("封号|箱号","工作单号='JPCD1312250019'")

For Each Ary As String() In Arys

    str = str & "," & vbcrlf & Ary(1)

    str1 = str1 & "," & vbcrlf & Ary(0)

    str= str.TrimStart(",")

    

    ' str1= str1.TrimStart(",")

    ' str= str.Replace("""",str)

    Output.Show(str)

    ' Output.Show(str1)

Next

  这个代码因为str= str.TrimStart(",")后第一个会有一个空格,怎去除这个空格?
