错误：“索引1没有值”怎么解决？ [英] Error: "index 1 does not have a value" how to fix it?

问题描述

单击datagridview包含数据时出错......（行，单元格，标题）



我不明白错误！



我认为问题在下面的代码中...

Error when click on datagridview contain data...(Row, Cells, Header)

I don''t understand error!

I think problem is here in the below code...

private void CreateTable(DataGridView grdvTest, ref DataTable table)
        {
            if (dgvResults.CurrentRow.Cells[1].Value != null)
            {
                int num = 0;
                while (num < grdvTest.ColumnCount)
                {
                    table.Columns.Add(grdvTest.Columns[num].HeaderText);
                    num++;
                }
                foreach (DataGridViewRow row in (IEnumerable)grdvTest.Rows)
                {
                    DataRow row2 = table.NewRow();
                    for (num = 0; num < row.Cells.Count; num++)
                    {
                        //row2[num] = (row.Cells[num].Value != null) ? row.Cells[num].Value.ToString().Replace(" ", " ") : "";
                        if (row.Cells[num].Value != null)
                            row2[num] = row.Cells[num].Value.ToString().Replace(" ", " ");
                        else
                            row2[num] = "";
                    }
                    table.Rows.Add(row2);
                }
            }

我的应用：搜索google =>填充到datagridview =>点击=>错误！



请帮忙！

推荐答案

尝试调试并单步执行源代码。

它应该引导你到达实际可行的行抛出错误。



请注意，问题可能不在同一行，而在于填充此数据的方式。

Try debugging and stepping through your source code.
It should lead you to the line that could actually be throwing the error.

Note that the problem could not be in the same line but in the way you are populating this data.
