From your above code, the part of SQL Statement is - "select name,b_date from date where date between"

从上面的代码中,SQL语句的部分是 - “选择名称,b_date从日期之间的日期”

Can you please make sure the following:

你能否确认以下内容:

  1. Is "date" column there in the "date" table? should it be "b_date" instead of "date" or it is correct?

    “日期”列中是否有“日期”列?应该是“b_date”而不是“date”还是正确的?

  2. Can you please post what exception/error you are getting?

    您能否发布您遇到的异常/错误?

Thanks

DateTime should be formatted to be valid in sql, the format can be like yyyyMMdd,that is:

DateTime应格式化为在sql中有效,格式可以像yyyyMMdd,即:

SqlConnection con = new SqlConnection("my connection ");

SqlDataAdapter da = new SqlDataAdapter("select name,date from date where date between'"+ Convert.ToDateTime( datePicker2.SelectedDate.ToString("yyyyMMdd")+"' and  '"+ Convert.ToDateTime( datePicker3.SelectedDate.ToString("yyyyMMdd"))+"'",con);

DataSet ds = new DataSet();

da.Fill(ds, "entry");

da.Dispose();

dataGrid1.DataContext = ds.Tables["entry"].DefaultView;
