Answer 1

也许试试这个？

public DataTable GetDataTableFromDataGridView(DataGridView dataGridView)
{
    DataTable dataTable = new DataTable();
    foreach (DataGridViewColumn column in dataGridView.Columns)
    {
        //// I assume you need all your columns.
        dataTable.Columns.Add(column.Name, column.CellType);
    }

    foreach (DataGridViewRow row in dataGridView.Rows)
    {
        //// If the value of the column with the checkbox is true at this row, we add it
        if (row.Cells["checkbox column name"].Value == true)
        {
            object[] values = new object[dataGridView.Columns.Count];

            for (int i = 0; i < row.Cells.Count; i++)
            {
                values[i] = row.Cells[i].Value;
            }
            dataTable.Rows.Add(values);
        }
    }

    return dataTable;
}

Answer 2

假设您知道如何发送DataGridViewRow个对象的集合，以下是您应该只检查那些被检查的对象：

var rows = yourDataGridView.Rows.Cast<DataGridViewRow>().Where(row => (bool)
    (row.Cells["name of checkbox column!"] as DataGridViewCheckBoxCell).Value);

如果您的DataGridView是数据绑定的，当然您应该直接对数据进行操作，而不是在DataGridViewCells周围进行杂乱和转换。

与没有LINQ的上述相同：

var rows = new List<DataGridViewRow>();
foreach(DataGridViewRow row in yourDataGridView.Rows)
    if((bool)(row.Cells["name of checkbox column!"] as DataGridViewCheckBoxCell).Value)
        rows.Add(row);
