我正在用C#创建一个测试屏幕，提出一个问题，并给出3个答案以选择一个和两个按钮(下一个和上一个)以获取下一个问题或返回上一个问题.数据集中的下一个和上一个.
我必须使用数据集而不是阅读器，因为我将保存用户为每个问题选择的答案.

Hope this[^] might help you.

//Consider having the following DataSet
DataSet myDS = new DataSet();

//Consider you filled your DataSet from somewhere
string question = myDS.Table["table_name"].Rows[rowNumber].["column_name"]

您要做的就是从rowNumber值中添加/减去来得出下一个/上一个问题.

All you have to do is to add / subrtact from the rowNumber value to get the next / previous question.
