听到错误如何解决此问题 [英] hear got error how to rectify this

问题描述

Label l = default(Label);
		l = (Label)v.FindControl("Label1");
		l.Text = dt.Rows[ctr]["Serial"] +  ",";
		l = (Label)v.FindControl("Label2");
        dt.Rows[ctr]["question"] = l.Text;

我收到错误l.Text = dt.Rows [ctr] ["Serial"] +，";在此行中没有行.

I got error l.Text = dt.Rows[ctr]["Serial"] + ","; in this line there is no position at row.

cmd.Parameters["@password"].Value = this.TextBox2.Text;

      SqlDataReader dr = null;

      dr = cmd.ExecuteReader();

      if (dr.HasRows)
      {

我在这一行出现了错误dr = cmd.ExecuteReader();


感谢valuabel replay

thanks for valuabel replay

推荐答案

您的代码似乎不完整或不知道您想做什么.

Your code seems incomplete or dont know what you want to do.

dt.Rows[ctr]["Serial"]

在此代码中，什么是ctr，行是锯齿状数组，其中第一个边界是columnName/Id，第二个边界是RowID/RownNumber，因此您的代码应类似于-

In this code what is ctr, Rows is jagged array where first boundary is columnName/Id and second boundary is RowID/RownNumber so your code should be like -

dt.Rows[ColumnName/ID][RowID] 

您打算如何使用此代码?

subbu，

我认为您的cmd对象不会返回这些值.因此，您正在获得此期望.
只需在Sql Server Management Studio中执行querey，就会发现所犯的错误.

希望有更多问题，请发送查询.

Just execute your querey in Sql Server Management Studio,you will find the mistake you committed.

I hope it helps you, any more problem,please send a query.
