推荐答案

此处给出了ListView 的示例http://msdn.microsoft.com/en-us/library/system.windows .forms.listview.listviewitemcollection.aspx#Y3100 [ ^ ]

在上面的示例中， two columns,与问题中指定的列数相似.

以下代码

An example on ListView is given here http://msdn.microsoft.com/en-us/library/system.windows.forms.listview.listviewitemcollection.aspx#Y3100[^]

In the above example there are two columns, similar to the number of columns specified in the question.

The following code

Dim lv4 As ListViewItem = lvexp.Items.Add(cb_exp.Text)
lv4.SubItems.Add(txt_amt.Text)

在ListView 中添加了另一行，没有任何错误.

请参见上面的示例.我认为这可能会有所帮助.

added another row in the ListView without any error.

Please see the above example. I think it may be helpful.

PunithaSabareeswari395，

您需要声明一个新对象，在这种情况下，是一个ListViewItem，它将保存必须添加到Listview中的所有数据，然后使用AddRange而不是Add将其添加到您的listview中.这是因为，如果仅使用添加"，则仅传递一项，但如果使用添加范围"，则可以传递任意数量的项

以下是解决您的问题的示例代码.

hi PunithaSabareeswari395,

You need to declare a new object, in this case, a ListViewItem that will hold all the data that has to be added in the Listview and then add it in your listview using AddRange and not Add. This is because, if you use Add only, you pass only one item but if you use AddRange, you can pass as many items as you want

Below is a sample code to solve your problem.

Dim mylists As New ListViewItem(New String() {cb_exp.Text}, -1)
        ListView1.Items.AddRange(New System.Windows.Forms.ListViewItem() {mylists})
        ListView1.Focus()

只是尝试这个.希望对您有帮助！ :)

Just try this. Hope it helps you! :)
