主题：代码

完整的代码是这样的

Dim tpb As WinForm.TopicBar = e.Form.Controls("D110-任务栏")
Dim page As WinForm.TopicPage = tpb.Pages("计划任务")
Dim rwids As New List(Of String)
rwids = DataTables("LC01_流程任务").SQLGetValues("任务ID","任务名称 = '分项工程录入' and 任务计划_完成责任人 = '" & _UserName & "' and 完成复核_已复核 = 0")
For Each rwid As String In rwids
    Dim lcdr As DataRow = DataTables("LC01_流程任务").SQLFind("任务ID = '" & rwid & "'")
    Dim gcid As String = lcdr("单位工程ID")
    Dim mldr As DataRow = DataTables("XM01_项目目录").SQLFind("单位工程ID = '" & gcid & "'")
    Dim gczhm As String = mldr("单位工程组合名")
    Dim zt As String = lcdr("完成复核_完成状态")
    Dim rwmc As String = rwid
    Dim kg As New String(" ",80 - rwid.Length - gczhm.Length - zt.Length)
    Dim rwbt As String = "任务ID " & rwid & "  单位工程 " & gczhm & kg & zt
    page.Links.Add(rwid,rwbt)
Next

后来尝试着修改成这样就没报错了，不明白其中是什么原因。

Dim rwids As New List(Of String)
rwids = DataTables("LC01_流程任务").SQLGetValues("任务ID","任务名称 = '分项工程录入' and 任务计划_完成责任人 = '" & _UserName & "' and 完成复核_已复核 = 0")
For Each rwid As String In rwids
    Dim tpb As WinForm.TopicBar = e.Form.Controls("D110-任务栏")
    Dim page As WinForm.TopicPage = tpb.Pages("计划任务")
    Dim lcdr As DataRow = DataTables("LC01_流程任务").SQLFind("任务ID = '" & rwid & "'")
    Dim gcid As String = lcdr("单位工程ID")
    Dim mldr As DataRow = DataTables("XM01_项目目录").SQLFind("单位工程ID = '" & gcid & "'")
    Dim gczhm As String = mldr("单位工程组合名")
    Dim zt As String = lcdr("完成复核_完成状态")
    Dim rwmc As String = rwid
    Dim kg As New String(" ",80 - rwid.Length - gczhm.Length - zt.Length)
    Dim rwbt As String = "任务ID " & rwid & "  单位工程 " & gczhm & kg & zt
    page.Links.Add(rwid,rwbt)
Next
