4,5 5等位置没有排 [英] No row at position 4 5 6 etc

问题描述

我知道它被问了很多，而且我已经看了很多这个，但我给出的所有解决方案，但似乎没有什么工作适用于我的情况，所以我想发布我的解决方案，这是不起作用的 System.Data.dll中发生'System.IndexOutOfRangeException'类型的未处理异常



附加信息：位置16处没有行。我已经完成了调试数据库可视化器有行但它没有返回行...除了问题它只返回一个从12上索引更改



什么我试过了：



qdisplay.Text = quest_.Rows [questNo] [Question]。ToString（）。ToLower（）; //例外这里

radioButton1.Text = quest_.Rows [questNo] [Opt1]。ToString（）。ToLower（）;

radioButton2.Text = quest_。行[questNo] [Opt2]。ToString（）。ToLower（）;





questNo ++;



}

else

{

MessageBox.Show（empty）;

}

i know its been asked alot and i have looked alot into this but all the solution that are given i have used but nothing seems to work for my case ,, so i thought to post my solution that is not working here"An unhandled exception of type 'System.IndexOutOfRangeException' occurred in System.Data.dll

Additional information: There is no row at position 16." i have done debugging database visualizer has rows but it is not returning rows ... in addition to problem it returns only one from 12 on index changed

What I have tried:

qdisplay.Text = quest_.Rows[questNo] ["Question"].ToString().ToLower(); // exception here
radioButton1.Text = quest_.Rows[questNo]["Opt1"].ToString().ToLower();
radioButton2.Text = quest_.Rows[questNo]["Opt2"].ToString().ToLower();


questNo++;

}
else
{
MessageBox.Show("empty");
}

推荐答案

我自己解决了...只是索引就像我已经从0增加到1而问题解决了

i have solved it myself ... just index was out like i have incremented it from 0 to one and problem solved
