尝试运行此代码时,我一直收到“输入字符串格式不正确”的错误。

结果是将数据从一个列表框检索到另一个列表框,仅传输数据的某些部分。

Private Sub LoadButton_Click(sender As Object, e As EventArgs) Handles LoadButton.Click
    'checks there is raw data loaded 
    If RawDataListBox.Items.Count = 0 Then
        MessageBox.Show("No Data Has Been Loaded")
        Exit Sub
    End If
    'Splits the raw data into the structure
    Try
        Dim counterInteger As Integer = 12
        Dim FinalDataStructure(RawDataListBox.Items.Count) As FinalData
        Dim CleanDataString As String

        While counterInteger < RawDataListBox.Items.Count
            'reads one row into a string
            Dim FinalDataLineString As String = RawDataListBox.Items(counterInteger).ToString
            'Splits string by comma
            Dim FinalDataArrayString As String() = FinalDataLineString.Split(","c)
            FinalDataLineString.Replace("""", " ")

            With FinalDataStructure(counterInteger)
                .LocationNameString = FinalDataArrayString(0)
                .TypeString = FinalDataArrayString(1)
                .StateString = FinalDataArrayString(2)
                .FemalesInteger = Integer.Parse(FinalDataArrayString(3))
                .MalesInteger = Integer.Parse(FinalDataArrayString(4))
                'calculate the percentages and totals
                .TotalInteger = .FemalesInteger + .MalesInteger
                .PercentageFemaleInteger = .FemalesInteger + .TotalInteger
                .PercentageMaleInteger = .MalesInteger + .TotalInteger


            End With
            CleanDataString = "Location" + FinalDataStructure(counterInteger).LocationNameString + ","
            CleanDataString += "Type" + FinalDataStructure(counterInteger).TypeString + ","
            CleanDataString += "State" + FinalDataStructure(counterInteger).StateString + ","
            CleanDataString += "Females" + FinalDataStructure(counterInteger).FemalesInteger.ToString + ","
            CleanDataString += "Males" + FinalDataStructure(counterInteger).MalesInteger.ToString + ","
            CleanDataString += "Female Percentage" + FinalDataStructure(counterInteger).PercentageFemaleInteger.ToString + ","
            CleanDataString += "Male Percentage" + FinalDataStructure(counterInteger).PercentageMaleInteger.ToString + ","
            CleanDataString += "Total Population" + FinalDataStructure(counterInteger).TotalInteger.ToString + ","
            'Add to list box
            FinalDataListBox.Items.Add(CleanDataString)

            counterInteger += 1
        End While
    Catch ex As Exception
        MessageBox.Show(ex.Message)
    End Try
End Sub
