Question

如果我通过鼠标点击列表视图的项目，颜色将变为＆＃34;突出显示＆＃34;颜色，但如果我这样做的代码： （MultiSelect应为True，我也将HideSelection设置为False）

myListView1.Items[2].Selected = true;

那么它将是灰色......糟糕！当我用鼠标手动点击它时，我希望它是相同的高亮颜色:(

我也尝试添加此代码，但这也没有用，仍为灰色

myListView1.Items[2].BackColor = System.Drawing.Color.Blue;

Answer 1

这是ListView选择项目时的行为，但不重点。

所以，要获得你所追求的'蓝色'颜色，只需添加它;

listView1.Focus();

Answer 2

你可以在listview的SelectedIndexChanged事件中试试吗？

ListViewItem lv = YourListview.GetItemAt(YourListView.PointToClient(Cursor.Position).X, YourListView.PointToClient(Cursor.Position).Y);

// this kind of Control.GetItemAt() works everywhere you need to find your mouse position ;)

// if you need to find position for screen (i.e. if you want to show a messagebox at the center of screen) you can use PointToScreen instead of PointToClient

 if (lv == null) 
 { 
   return; 
 }

else if (yourfirstpossibility == true)
{
  lv.Selected = true;
  lv.BackColor = Color.FromKnownColor(KnownColor.ButtonHighLight);

 // or which color you prefer. FromKnownColor retrieves system colors which you can see in backcolor / forecolor property => "system" named palette

}

这个代码有点不同（更复杂）我在list_checked事件中使用我的listview ..希望它可以帮助你..
