c# 中怎么用FOR 循环给 textBox 赋ID 例 textBox1 textBox2 谁能给我个完整的案例 782189035@QQ.COM

for (int i = 1; i < 4; i++)
{

TextBox tb = this.FindControl("TextBox" + i) as TextBox;
tb.Text = i.ToString();

}
FindControl 报错

Answer 1

TextBox tb = this.FindControl("TextBox" + i) as TextBox;

应该是

TextBox tb = this.FindControl("textBox" + i) as TextBox;
吧？

Answer 2

this.FindControl("TextBox" + i,true)

要寻找所有子控件的子控件。你的TextBox不是在顶层容器里。

Answer 3

this.FindControl有这个方法吗？？
foreach (Control c in this.Controls)
{
if (c is TextBox)
{
//
}
}

Answer 4

string[] arr=new string[]{"a","b"};
for(int i=0;i<2;i++)
{
((TextBox)form1.FindControl("TextBox"+(i+1).ToString())).Text=arr[i];
}
