使用vb.net来填充字符串 [英] to fomat an string using vb.net

问题描述

如何使用 vb.net自动格式化此字符串

  Dim  stext  as   string  =    1A 
  Dim  stext1  as   string  =   A1 
  Dim  sout，sout1  As   String  
 sout = 字符串 .Format（  0000，stext）
 sout1 = 字符串 .Format（  0000，stext1）

但我得到输出为：< br $> b $ b

 stext = 0000 
 stext1 = 0000 

但是我需要一个输出：

 stext = 001A 
 stext1 = 00A1 

Kinldy做必要的

解决方案

 sout =   00 + stext; 
 sout1 =   00 + stext1; 

看看这里：如何：用前导零填充数字 [ ^ ]

更好的方法是创建自定义格式提供程序：如何：定义和使用自定义数字格式提供程序 [ ^ ]

  Dim  yourNumber  as   Int32  =  5  
 yourNumber.ToString（  D2）'  =05 

how to format this string automatically using vb.net

Dim stext1 as string ="A1"
Dim sout,sout1 As String
sout= String.Format("0000", stext )
sout1 = String.Format("0000", stext1 )

but iam getting output as :

stext = 0000
stext1= 0000

But i need an output as :

Kinldy do the needfull

解决方案

Have a look here: How to: Pad a Number with Leading Zeros[^]
And even better way is to create custom format provider: How to: Define and Use Custom Numeric Format Providers[^]

Dim yourNumber as Int32 = 5
yourNumber.ToString("D2") '= "05"
