1.存储过程返回的表结构确定,不会发生改变,直接通过索引访问——高效
foreach(DataRow row in table.Rows)
...{
customer = new Customer();
customer.ID = (Int32)row[0];
customer.FirstName = row[1].ToString();
customer.LastName = row[2].ToString();
}
2.返回的表结构经常发生变化,采用如下方式访问
int customerIDIndex = table.Columns.IndexOf("customerID");
int customerFirstNameIndex = table.Columns.IndexOf("firstName");
int customerLastNameIndex = table.Columns.IndexOf("lastName");
foreach(DataRow row in table.Rows)
...{
customer = new Customer();
if(customerIDIndex > -1)
customer.ID = (Int32)row[customerIDIndex];
if(customerFirstNameIndex > -1)
customer.FirstName = row[customerFirstNameIndex].ToString();
if(customerLastNameIndex > -1)
customer.LastName = row[customerLastNameIndex].ToString();
}
