在C＃Windows窗体中检查两个DataGridViews是否相等

Question

I have two datagridviews. I want to check if both of them are same or not, the columns are always the same. I just want to check if the rows are same or not.

Answer 1

There may be better ways, but ...

    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());

    }
