Split a String into 2 Variables
提问by Ron
What I'm trying to do here is Capture 2 Variables from a Textbox
我在这里要做的是从文本框中捕获 2 个变量
Here is an example of whats going to be in here.
下面是一个例子，说明这里将要发生的事情。
User:Pass
User:Pass
I want to declare everything before the :as user and everything after the :as pass.
我想声明:as 用户之前的所有内容以及:as 传递之后的所有内容。
I've Googled, and found a few things, but I couldn't seem to get it working fully.
我用谷歌搜索，发现了一些东西，但我似乎无法让它完全工作。

Dim words As String() = textbox1.text.Split(":")
Dim user as String = words(0)
Dim pass as String = words(1)

Dim str = "User:Pass"
Dim split = str.Split(":")
Dim user as String
Dim password as String
If (split.Count = 2) then
user=split(0).ToString()
password = split(1).ToString()
End If
Split on the :, if there are 2 entries in the resulting array, populate the user variable with the first item, and the password variable with the second.
拆分:，如果结果数组中有 2 个条目，则用第一项填充用户变量，用第二项填充密码变量。

Dim user As String
Dim pass As String
Dim iPosEQ As Integer
iPosEQ = textbox1.text.IndexOf(":", System.StringComparison.Ordinal)
kv(0) = textbox1.text.Substring(0, iPosEQ - 1)
kv(1) = textbox1.text.Substring(iPosEQ + 1)
This works even with passwords (or users) with ":"
这甚至适用于带有“：”的密码（或用户）
