Question

我正在尝试将DataGridView转换为DataTable，但我找到的所有sollution都没有用。任何的想法？或者我需要使用foreach等吗？

        DataTable d = detailsDataGridView.DataSource as DataTable;// return null table

        DataTable dt = new DataTable();
        dt = (DataTable)detailsDataGridView.DataSource;//doesn't work

        BindingSource bs = new BindingSource();
        bs.DataSource = detailsDataGridView.DataSource;
        DataTable d = (DataTable)(bs.DataSource);//doesn't work

尝试此方法，这就是您所需要的：

DataTable data = GetDataTableFromDGV(dgvMyMembers);

    private DataTable GetDataTableFromDGV(DataGridView dgv)
    {
        var dt = ((DataTable)dgv.DataSource).Copy();
        foreach (DataGridViewColumn column in dgv.Columns)
        {
            if (!column.Visible)
            {
                dt.Columns.Remove(column.Name);
            }
        }
        return dt;
    }
