Question

如何收集JUST文本框控件的值？

有没有办法在ASP.NET 4.0中指定它？

ArrayList alAnswerList = new ArrayList();

int iCount = 0;
NameValueCollection frmCollect = Request.Form;

iCount = frmCollect.Count;

for (int i = 0; i <= iCount; i++)
{
    alAnswerList.Add(frmCollect.GetValues(i));
}

我试图避免硬编码确切的索引值以开始获取值。

谢谢！

更新：控制代码

Answer 1

试试这个：

// You might not be able access the controls directly here. 
//As it might be on a master page,or Simple Page or a 
//Content Page or an User Control. Either you have to use FindControl() 
//or NamingContainer
    foreach(Control c in Page.Controls) 
    {
       if(c is TextBox)
       {
          var val = ((TextBox)c).Text; // or any other properties of textbox
       }
    }

Answer 2

在btnShowAnswers_Click内，添加以下代码：

var answers = new List<string>();

if(dlHunt.Items.Count > 0)
{
    foreach(DataListItem item in dlHunt.Items)
    {
        var textBox = (TextBox)item.FindControl("huntAnswerText");
        answers.Add(textBox.Text);         
    }
}

// At this point you have your list of answers and can handle as you see fit

使用NameValueCollection我怎样才能获得文本框控件值？
