在 c# windows 形式中检查两个 DataGridViews 是否相等

Question

我有两个数据网格视图。我想检查它们是否相同，列总是相同的。我只想检查行是否相同。

Answer 1

可能有更好的方法，但是...

    public Form1()
    {
        InitializeComponent();

        dgv1.Columns.Add(new DataGridViewTextBoxColumn());
        dgv1.Columns.Add(new DataGridViewTextBoxColumn());
        dgv1.Columns.Add(new DataGridViewTextBoxColumn());

        dgv1.Rows.Add(1, 2, 3);
        dgv1.Rows.Add(4, 5, 6);

        dgv2.Columns.Add(new DataGridViewTextBoxColumn());
        dgv2.Columns.Add(new DataGridViewTextBoxColumn());
        dgv2.Columns.Add(new DataGridViewTextBoxColumn());

        dgv2.Rows.Add(1, 2, 3);
        dgv2.Rows.Add(4, 5, 6);

        var ar1 = string.Join(",", (from row in dgv1.Rows.OfType<DataGridViewRow>()
                                    from cell in row.Cells.OfType<DataGridViewCell>()
                                    select cell.Value));

        var ar2 = string.Join(",", (from row in dgv2.Rows.OfType<DataGridViewRow>()
                                    from cell in row.Cells.OfType<DataGridViewCell>()
                                    select cell.Value));

        Debug.Print((ar1.Equals(ar2)).ToString());

    }
