string[] total_items = new string[50];
        int items = 0;

private void button1_Click(object sender, EventArgs e)
        {
            try
            {
                foreach (Control p in panel1.Controls)
                {
                    if (p.GetType() == typeof(CheckedListBox))
                    {
                        CheckedListBox getdata = new CheckedListBox();
                       total_items[items] = getdata.SelectedItem.ToString();
                        items++;
                        
                    }
                }


                dataGridView1.Columns.Add("Items", "Choosed Items");


                for (int cnt = 0; cnt < items; cnt++)
                {
                    dataGridView1.Rows.Add(total_items[cnt]);
                }

            }
            catch (SqlException err)
            {
                MessageBox.Show(err.Message);
            }
        }

推荐答案

您的代码不会像这样工作。 total_items应该是一个字符串列表。它应该是这样的，玩它来使事情有效：

Your code won't work like this. total_items should be a list of strings. It should be something like this, play around with it to make things work:

foreach (Control p in panel1.Controls)
{
    if (p.GetType() == typeof(CheckedListBox))
    {
        total_items.Clear();
        CheckedListBox getdata = (CheckedListBox)p;
        foreach (int index in getdata.CheckedIndices)
        {
            total_items.Add(getdata.Items[index].ToString());
        }
    }
}

dataGridView1.Rows.Clear();
dataGridView1.Columns.Add("Items", "Choosed Items");


for (int cnt = 0; cnt < total_items.Count; cnt++)
{
    dataGridView1.Rows.Add(total_items[cnt], true); // or something like that
}
