需要帮助进行字符串操作。 [英] need help with a string manipulation.
问题描述
您好，
我正在尝试创建一些动态控件，一旦它们被渲染
我需要保存输入这些动态的信息
fileds。
例如当我创建3个单选按钮动态控件时，我得到这个控件的ID
rdb29OPT0
rdb30OPT1
rdb31OPT2
....
现在我试图操纵上面的字符串，试着从他们那里获得29,30,31的
。有人可以帮助我如何只需要
值29并删除rdbOPT1作为第一个字符串？
提前谢谢

看一下mid"功能。

没有使用VisualBasic命名空间（我的偏好，不需要）
使用静态（Visual Basic中的Shared）子串方法：
Dim s As String =" rdb290PT0"
Dim n As String = s.Substring（3,2）

好吧可能会有很多值，例如
rdb1234OPT1234！
其中我只需要'rdb''
和''OPT1234'之间的数值'
我是寻找一种可以rdb的方法，以及
从OPT开始的那个词
希望这会给它带来一点内在。
谢谢

Hello,
I am trying to create few dynamic controls and once they are rendered
I need to save the information that was entered into these dynamic
fileds.
For instance when I create 3 radio button dynamic controls I get the ID
of this controls as
rdb29OPT0
rdb30OPT1
rdb31OPT2
....
Now I am trying to manipulate the the above string and just try getting
the 29, 30, 31 from them. Can some one help me with how do I just the
values 29 and remove rdbOPT1 for the first string?
Thanks in advance

Take a look at the "mid" funtion.

And without using the VisualBasic namespace (my preference, not required)
using using the static (Shared in Visual Basic) Substring method:
Dim s As String = "rdb290PT0"
Dim n As String = s.Substring(3, 2)

well there could be many values down the line for instance
rdb1234OPT1234 !
out of which I just need the numerical value that is in between ''rdb''
and ''OPT1234''
I am looking for kind of a method that could rdb and also the word that
starts with OPT
Hope this gives a little inside of it.
Thanks
