c# - 从 SqlDataReader 读取数据

Question

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

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

我知道读者有值(value)观。我的 SQL 命令是从表中只选择 1 列。该列仅包含字符串。我想一个一个地读取阅读器中的字符串(行)。我该怎么做？

Answer 1

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);
    }
}
