将 Datagridview 行数据与多列进行比较

Question

使用 C# WindowsForms，

我有 2 个 Datagridview，每个 Datagridview 有 2 列。

我想比较 DT1 和 DT2 行，如果在 DT2 行（Col1 和 Col2）中找到 DT1（Col1 和 Col2），则 DT1 行和 DT2 行将被删除/删除。

{
        bool MatchFound = false;

        List<int> IndexToRemoveFromGrid = new List<int>();


        //Loop Table 1 and get Row Values for Col1+Col2
        foreach (DataGridViewRow row in dataGridView1.Rows)
        {
            DataGridViewRow T1Col1row = dataGridView1.Rows[row.Index];
            DataGridViewRow T1Col2row = dataGridView1.Rows[row.Index];
            string T1Col1RX = (string)T1Col1row.Cells[0].Value + (string)T1Col1row.Cells[1].Value;

            MatchFound = false;

            //Loop Table 2 and get Row Values for Col1+Col2
            foreach (DataGridViewRow rowT2 in dataGridView2.Rows)
            {
                DataGridViewRow T2Col1row = dataGridView2.Rows[rowT2.Index];
                DataGridViewRow T2Col2row = dataGridView2.Rows[rowT2.Index];
                string T2Col1RX = (string)T2Col1row.Cells[0].Value + (string)T2Col1row.Cells[1].Value;

                if (MatchFound == false)
                {
                    //Compare Table 1 RX to Table2 RX , If matched then deleted row on both sides
                    if (String.Compare(T1Col1RX, T2Col1RX, false) == 0)
                    {
                        if (row.Index > -1 && rowT2.Index > -1)
                        {
                            IndexToRemoveFromGrid.Add(row.Index);
                        }
                        MatchFound = true;
                    }
                }
            }
        }

        for (int i = 0; i <= IndexToRemoveFromGrid.Count(); i++)
        {
            dataGridView1.Rows.RemoveAt(i);
            dataGridView2.Rows.RemoveAt(i);
        }
    }

您应该比较绑定到 DataGrid 的数据，这比访问网格本身的属性要好。
