我目前正在为学校做作业，经过几天的尝试后，我无法弄清楚如何从我的属性表单中获取ListBox以显示我的员工档案的内容一种可以编辑或添加信息的方式。有什么建议吗？
这是我在这里发表的第一篇文章，如果是这样，请告诉我： A）格式太差 B）缺少信息（例如表格设计） C）其他任何包含的东西都需要，我想

请使用datagridview而不是listbox（仅列出数据）。连接事件：因为这是为了课程。请研究代码并了解它的作用。
private void dataGridView1_RowLeave(object sender, DataGridViewCellEventArgs e)
{
var rowIndex = e.RowIndex;
var currentRowVals = dataGridView1.Rows[e.RowIndex];
var Id = currentRowVals.Cells[0].EditedFormattedValue;
var FName = currentRowVals.Cells[1].EditedFormattedValue;
var LName = currentRowVals.Cells[2].EditedFormattedValue;
var EmpType = currentRowVals.Cells[3].EditedFormattedValue;
var Salary = currentRowVals.Cells[4].EditedFormattedValue;
if (dataGridView1.IsCurrentCellDirty)
{
if (Id.ToString() == "-1")
{
//do add
}
else
{
//do edit
}
}
}
