我创建了一个包含三个选项卡的表单。下面的按钮位于一个选项卡下,单击时ListBox
会用文本文件中的项目填充 readBox。当我切换到另一个选项卡时,我无法弄清楚如何从 ListBox` 中删除项目。任何帮助,将不胜感激。谢谢。
private void read_Click(object sender, EventArgs e)
{
FileStream file = new FileStream(FileName, FileMode.OpenOrCreate, FileAccess.Read, FileShare.ReadWrite);
StreamReader read = new StreamReader(file);
string readIt;
string[] show;
string birthday;
readIt = read.ReadLine();
while (readIt != null)
{
show = readIt.Split(DELIM);
friend.FirstName = show[0];
friend.LastName = show[1];
friend.PhoneNumber = show[2];
birthday = show[3] + "/" + show[4];
readIt = String.Format("{0, -10}{1, -10}{2,-10}{3, -3}", friend.FirstName,
friend.LastName, friend.PhoneNumber, birthday);
readBox.Items.Add(readIt);
readIt = read.ReadLine();
}
read.Close();
file.Close();
}
