有没有更有效的方法在C#中创建我的DataTable？

DataTable dataTable = new DataTable();
dataTable.Columns.Add("Column1", typeof(string));
dataTable.Columns.Add("Column2", typeof(int));
dataTable.Rows.Add("Value1", 1);
dataTable.Rows.Add("Value2", 2);

DataSet dataSet = new DataSet();
DataTable dataTable = dataSet.Tables.Add("TableName");
dataTable.Columns.Add("Column1", typeof(string));
dataTable.Columns.Add("Column2", typeof(int));
dataTable.Rows.Add("Value1", 1);
dataTable.Rows.Add("Value2", 2);

var query = from data in dbContext.TableName
            select new
            {
                Column1 = data.Column1,
                Column2 = data.Column2
            };

DataTable dataTable = query.CopyToDataTable();
