关于数据读取器错误 [英] about data reader error

问题描述

此行发生错误:-Label6.Text = reader [0];

无法将类型"object"隐式转换为"string".存在显式转换(您是否缺少演员表?)

我无法理解的错误是什么....帮助我..

Error Occure on this line:-Label6.Text = reader[0];

Cannot implicitly convert type ''object'' to ''string''. An explicit conversion exists (are you missing a cast?)

what is mistake i cant understand....help me..

推荐答案

您需要将读取器值转换为字符串.您不能直接将阅读器值分配给标签文本.

它应该是

You need to cast the reader value to string. You cannot directly assign reader value to label text.

It should be

Label6.Text = reader.getValue(0);

您缺少ToString().应该是:

You are missing the ToString(). It should be :

Label6.Text = reader[0].ToString();

Label6.Text = reader [0] .ToString()

Label6.Text = reader[0].ToString()
