如何在asp.net应用程序中使用循环方法？ [英] How to use loop method in asp .net application ?
问题描述
在我的网页上有超过50个文本框。每个文本框用于填充特定总和的答案。这些Texbox分为5行。这意味着连续10个文本框。每个行Texbox都有一个值。每行包含10个总和。例如，第一行总和文本框值为2。即从texbox1 ..... textbox10答案是2.如果我们在textbox1中输入2，那么我们的正确答案是1.如果我们在textbox1中输入2到textbox10那么我们的正确答案是10.如果我们输入任何错误的答案然后它将b计为错误的答案（例如，如果我输入3为textbox5 ans。那么我对texbox1到texbox10的整体计算ll b正确的答案= 9，错误的答案= 1）。这就是我必须为我的整行做的事情。
现在我在这个页面要做的就是当我完成我的总和时，我必须得到全面的正确答案和错误的答案 对于5行总和。这意味着50个文本框值。我必须按一下按钮执行此操作。对于10个texbox，我做的是
in my web page there r more-than 50 text-boxes. Each textbox is used to fill the answer of paricular sums. These Texboxes are divided into 5 rows.That means 10 textbox in a row. Each Row Texbox has a single value. Each row contains 10 sums. For Example first row sum textbox value is 2 . ie from texbox1 .....textbox10 the answer is 2. If we type 2 in textbox1 then our correct answer is 1. If we type 2 in textbox1 to textbox10 then our correct answer is 10.if we type any wrong answer then it will b counted as wrong answer( for example if i type 3 for textbox5 ans. then my overall calculation for texbox1 to texbox10 ll b "CORRECT ANSWER =9 , WRONG ANSWER=1 ). This what i have to do for my whole Rows.
Now what i have to do in this page is when i finished my sums i have to get total "CORRECT ANSWER and WRONG ANSWER" for 5 row sums. That means 50 text box values.. I have to perform this in a button click. For 10 texboxes wat i did was
int _correct = 0;
int _wrong = 10;
if (txtbox1.Text == "5")
{
_correct++;
}
if (txtbox1.Text == "3")
{
_correct++;
}
.
.
.
.
.
.
int _wrongfinal = _wrong - _correct;
lblCorrextAnswer.Text = _correct.ToString();
lblWrongAnswer.Text = _wrongfinal.ToString();
对于50 texbox我认为这不是一个好方法。我可以用循环方法吗？我怎样才能做到这一点？我应该使用Tabindex进行循环吗？
For 50 texbox i think this is not a good method. Can i do this with loop method?. How can i do that? Should i use Tabindex for looping?
推荐答案
在你的HTML添加文本框中输入正确值
On your HTML add text box with correct value to check
<asp:textbox id="TextBox1" runat="server" valuetocheck="4" xmlns:asp="#unknown"></asp:textbox>
这是通过循环来完成的。
form1.Controls这里form1是控件的名称包含文本框控件。你可以相应地调整条件。
This is how to do it through loop.
form1.Controls here form1 is the name of control that contains the textbox controls. You can adjust the conditions accordingly.
int _correct = 0;
int _wrong = 0;
foreach (Control cntrl in form1.Controls)
{
if (cntrl.GetType().Name == "TextBox")
{
TextBox txt = (TextBox)cntrl;
string Valuetocheck = txt.Attributes["valuetocheck"];
string GetInputValue = txt.Text;
if (Valuetocheck == GetInputValue)
{
_correct++;
}
else
{
_wrong++;
}
}
}
