asp.net - 没有显示错误时无法构建解决方案

Question

我有一个问题，我尝试构建我的项目，但每次构建时，它都说有错误，但在错误框中没有显示错误。我可以知道是什么原因造成的吗？这是我的编码

Dim sTmp As String
        Dim aTmp(), bTmp() As String
        Dim MRWS As New MobileReload_WS.MobileReload_WS
        Dim aTelco(12, 3) As String
        Dim aProduct(12, 3) As String
        Label1.Text = "0.0"
        sTmp = MRWS.LoadTelco_WS()
        If sTmp = "" Then
            Exit Sub
        Else
            aTmp = Split(sTmp, "|", )
            For i = 0 To UBound(aTmp)
                bTmp = Split(aTmp(i), ";")
                For j = 0 To UBound(bTmp)
                    aTelco(i + 1, j) = bTmp(j)
