这将有助于在datagridview中添加新的datarowdatagridview1.Rows.add();This will help to add new datarow in datagridview试试这个Try thisDataTable ds = (DataTable)dataGridView1.DataSource; DataRow dr = ds.NewRow();//index is selected row's index ds.Rows.InsertAt(dr, index + 1); dataGridView1.DataSource = ds; 这篇关于如何在C＃win表单中向数据网格视图添加空行的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
