【问题描述】：

我刚刚学习 vb，在我的文本框中输出特定检查项目时遇到了一些问题。试了很多方法还是找不到合适的方法，可能是我忘记了什么？

    Private Sub submitBtn_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles submitBtn.Click
    Dim output As String
    Dim listOfProd As String
    listOfProd = ""


    output = "Selected Region: " + destination.Text + Environment.NewLine + "Seleted Place: " +
        places.SelectedItem + Environment.NewLine + "Accomodation: " +
        accomodation.Text + Environment.NewLine + "Products Selected: " + Environment.NewLine

    For i As Integer = 0 To products.Items.Count
        If products.Items(i) Is products.CheckedItems Then
            listOfProd = listOfProd + products.Items(i)

        End If
    Next

    output = output + listOfProd

    outputHere.Text = output

【解决方案1】：

不用循环确定选中哪些复选框列表项，只需使用CheckedItems 集合，如下所示：

' Loop through only the items that are checked 
For Each itemChecked In products.CheckedItems
    ' Get the text of the selected item and append it to the output string
    listOfProd = listOfProd + itemChecked.ToString()
Next
