如何将Vb.Net中的数字拆分为两个 [英] How Can I Split A Number In Vb.Net Into Two

问题描述

我需要检查条形码是否以27开头。如果是，我需要在文本框中输入此条形码的前6位数，其他文本框中的其余数字如何在vb.net中执行此操作？任何帮助将不胜感激

我如何使用split方法来做那个或正则表达式或什么？

解决方案

你知道吗String类型有一个Substring方法？

所以伪代码（即粗略的代码，实际上不是任何语言，除了字符串Substr和Remove ARE VB）

 if barCodeString .Substr（0,2）=='27'
 //将条形码的前6个字符放入TextBox 1 
 TextBox1.Text = barCodeString.Substr（0,6）
 //创建一个临时字符串，以便不改变原始
字符串TempString = barCodeString 
 //删除前6个字符
 TempString.Remove（0,6） 
 //将剩余物放入TextBox2 
 TextBox2.Text = TempString 
 end 

为何复杂化正则表达式的东西？你只需要将我所投入的内容转换为适当的VB

guys i need to check if a barcode number starts with 27. if it does, i need to have the first 6 digitsnof this barcode in a textbox and the rest digits in another textbox how can i do that in vb.net? any help would be appreciated
how can i use the split method to do that or regular expressions or something?

解决方案

you do know the String type has a Substring method ?

https://msdn.microsoft.com/en-us/library/aka44szs(v=vs.110).aspx[^]

so in pseudocode (ie rough code thats not really any language except the string Substr and Remove ARE VB)

if barCodeString.Substr(0,2) == '27'
    // Put 1st 6 chars of bar code into TextBox 1
    TextBox1.Text = barCodeString.Substr(0,6)
    // Create a temporary String so as to not alter original
    String TempString = barCodeString
    // Delete the 1st 6 characters
    TempString.Remove(0,6)
    // Put the Remainder in TextBox2
    TextBox2.Text = TempString
end

Why complicate things with Regular expressions ? you just have to turn what Ive put into proper VB
