从 SqlDataReader 读取数据 [英] Read data from SqlDataReader

问题描述

我有一个 SQL Server 2008 数据库，我正在后端处理它.我正在研究 asp.net/C#

I have a SQL Server 2008 database and I am working on it in the backend. I am working on asp.net/C#

SqlDataReader rdr = cmd.ExecuteReader();  
while (rdr.Read())  
{              
   //how do I read strings here????  
}  

我知道读者有价值观.我的 SQL 命令是从表中只选择 1 列.该列仅包含字符串.我想一一读取阅读器中的字符串(行).我该怎么做?

I know that the reader has values. My SQL command is to select just 1 column from a table. The column contains strings ONLY. I want to read the strings (rows) in the reader one by one. How do I do this?

推荐答案

using(SqlDataReader rdr = cmd.ExecuteReader())
{
    while (rdr.Read())
    {
        var myString = rdr.GetString(0); //The 0 stands for "the 0'th column", so the first column of the result.
        // Do somthing with this rows string, for example to put them in to a list
        listDeclaredElsewhere.Add(myString);
    }
}
