Question

如何循环的给textbox赋值

我现在要的是。我有textbox1~~~~textboxN，textbox1=1~~~textboxN=N.

Answer 1

int N = 4;
for (int i = 1; i <= N; i++)
{
TextBox tb = this.Controls["TextBox" + i.ToString()] as TextBox;
if (tb != null)
{
tb.Text = i.ToString();
}
}
这个是你要求的,即使上面有别的不是textBox?为名的TextBox也可以

Answer 2

TextBox txt = null;
foreach (Control c in Page.Controls)
{
if (c.GetType().Name == "HtmlForm")
{
foreach (Control c1 in c.Controls)
{
if (c1.GetType().Name == "TextBox")
{
txt = ((TextBox)c1);
txt.Text = "N";
}
}
}
}
