假设您有一个gridview" gdvContacts和cellclick事件如下方法.
还要假设您在网格视图上有一个删除"按钮.

Assuming, you have a gridview "gdvContacts" and cellclick event as below method.
Also assuming you have a Delete button on grid view.

private void gdvContacts_CellClick(object sender, DataGridViewCellEventArgs e)
{
    try
    {
        if (!(e.RowIndex < 0 || e.ColumnIndex < 0))
        {
            DataGridViewButtonCell cell = gdvContacts.Rows[e.RowIndex].Cells[e.ColumnIndex] as DataGridViewButtonCell;
            if (cell != null)
            {
                string strTest = cell.OwningColumn.HeaderText;
                if (strTest == "Delete" || strTest == "Update")
                {
                    if (strTest == "Delete")
                    {
                        DialogResult result;
                        result = MessageBox.Show("Are you sure want to delete the selected contact?", "Delete Contact ?", MessageBoxButtons.OKCancel, MessageBoxIcon.Question);
                        if (result == DialogResult.OK)
                        {
                            string ID = gdvContacts.Rows[e.RowIndex].Cells[e.ColumnIndex - 4].Value.ToString();
                             this.gdvContacts.Rows.RemoveAt(cell.RowIndex);
                        }
                    }



                }
            }
            gdvContacts.EditMode = DataGridViewEditMode.EditOnEnter;
        }

    }
    catch { }
}

如果没有删除按钮，请在填充gridview之后添加它:

if you do not have Delete button, add it after populate gridview :

if (this.gdvContacts.Rows.Count > 0)
            {

                DataGridViewButtonColumn dt = new DataGridViewButtonColumn();
                dt.HeaderText = "Delete";
                dt.Text = "Delete";
                dt.Name = "Delete";
                dt.ToolTipText = "Delete this row";
                dt.Width = 55;
                dt.UseColumnTextForButtonValue = true;
                gdvContacts.Columns.Add(dt);
}
