如何生成List< String>从SQL查询?

问题描述：

如果我定义了DbCommand来执行类似的操作:

If I have a DbCommand defined to execute something like:

SELECT Column1 FROM Table1

生成返回记录的List<String>的最佳方法是什么?

What is the best way to generate a List<String> of the returned records?

没有像我正在使用VS2005的Linq等.

No Linq etc. as I am using VS2005.

答

我认为这就是您想要的.

I think this is what you're looking for.

List<String> columnData = new List<String>();

using(SqlConnection connection = new SqlConnection("conn_string"))
{
    connection.Open();
    string query = "SELECT Column1 FROM Table1";
    using(SqlCommand command = new SqlCommand(query, connection))
    {
        using (SqlDataReader reader = command.ExecuteReader())
        {
            while (reader.Read())
            {
                columnData.Add(reader.GetString(0));
            }         
        }
    }
}

未经测试，但这应该可以正常工作.

Not tested, but this should work fine.
