将Linq变量行追加到dataTable c#

var query = from item in collection
            select new
            {
                Column1 = item.Property1,
                Column2 = item.Property2,
                // 其他列...
            };

DataTable dataTable = new DataTable();
dataTable.Columns.Add("Column1", typeof(string));
dataTable.Columns.Add("Column2", typeof(int));
// 其他列...

foreach (var item in query)
{
    DataRow row = dataTable.NewRow();
    row["Column1"] = item.Column1;
    row["Column2"] = item.Column2;
    // 其他列...
    dataTable.Rows.Add(row);
}
