c# - 从 Listview 限制 C# 中 DataGrid View 中的重复值？

Question

使用 ListView 控件在 MouseDoubleClick_event 上向 DataGridView 添加行行被添加到 DataGrid 但它也添加了重复行。有没有办法处理重复值

   ArrayList arrListChkIDs = new ArrayList();
        if (dgvPriceView.Rows.Count > 0)
        {
            for (int i = 0; i < dgvPriceView.Rows.Count - 1; i++)
            {
                arrListChkIDs.Add(dgvPriceView.Rows[i].Cells["Code"].Value);
            }

        }

Getting Unique Value In array List to compare With My ListView Value Now How Should I Compare It??

Answer 1

嘿，现在从这里开始非常简单

ArrayList arrListChkIDs = new ArrayList();
//Now Get and Check The Code from List View or put the Index Number  at subItems
string Code = listView.SelectedItems[0].SubItems["Code"].Text;
if (!arrListChkIDs.Contains(Code))
{

}
else
{
    MessageBox.Show("Row Already Exist!",
                    MessageBoxButtons.OK, 
                    MessageBoxIcon.Error);
    return;
}
