FileInfo fi = new FileInfo(files[i]);
if (listView1.Items.Contains(fi.FullName))
错误已开启:
listView1.Items.Contains(fi.FullName)
错误2参数1:无法从'string'转换为'System.Windows.Forms.ListViewItem'
和
错误1'System.Windows.Forms.ListView.ListViewItemCollection.Contains(System.Windows.Forms.ListViewItem)'的最佳重载方法匹配有一些无效的参数
在我的代码底部我有这个:
private void button5_Click(object sender, EventArgs e)
{
if (button5.Text == "Unselect All Items")
{
for (int i = 0; i < listView1.Items.Count; i++)
{
listView1.SetSelected(i, false);
}
button5.Text = "Select All Items";
}
else
{
if (listView1.Items.Count == 0)
{
}
else
{
for (int i = 0; i < listView1.Items.Count; i++)
{
listView1.SetSelected(i, true);
}
button5.Text = "Unselect All Items";
}
}
}
但是listView1在我拥有listBox之前没有属性SetSelected但现在我正在使用listView有没有办法克服它?
答案 0 :(得分:5)
试试这个:
if (listView1.Items.Cast<ListViewItem>().Any(item=>item.Text == fi.FullName))
{
// whatever you want
}
