我的代码如下（asp.net2005）
For Each c As Control In Page.Controls
If TypeOf c Is TextBox Then
Select Case c.ClientID
Case "TextBox1"
DirectCast(c, TextBox).Text = "a1"
Case "TextBox2"
DirectCast(c, TextBox).Text = "a2"
Case "TextBox3"
DirectCast(c, TextBox).Text = "a3"
End Select
End If
Next
不知道哪里出错，就是不能赋值。请各路高手指点

- VB.NET code
For Each c As Control In Me.Controls If c Is TextBox Then Select Case c.ClientID Case "TextBox1" DirectCast(c, TextBox).Text = "a1" Case "TextBox2" DirectCast(c, TextBox).Text = "a2" Case "TextBox3" DirectCast(c, TextBox).Text = "a3" End Select End If Next
