问题描述
我有一个包含2列数字的列表框我想用零或空格填充数字,这样它们就等于3个字符,所以它们对齐。我尝试了以下代码 但我必须遗漏一些东西。
看起来像这样
4 786
123 265
34 123
128 2
我希望它看起来像这样
004 786
123 265
034 123
123 002
Private Sub Button3_Click(sender As Object,e As EventArgs)Handles Button3.Click
For Each c As Char in ListBox1 .Items
Dim i As String =" 1234567890"
Dim count As Integer = 0
如果i.Count = 1则
i.PadLeft(2).ToString()
ElseIf i.Count = 1则
i.PadLeft(1).ToString()
End if
Next
End Sub
解决方案
I have a list box with 2 columns of numbers I would like to pad the numbers with zeros or spaces, so that they equal 3 characters so they align. I tried the following code but I must be missing something.
Looks like this
4 786
123 265
34 123
128 2
I want it to look like this
004 786
123 265
034 123
123 002
Private Sub Button3_Click(sender As Object, e As EventArgs) Handles Button3.Click For Each c As Char In ListBox1.Items Dim i As String = "1234567890" Dim count As Integer = 0 If i.Count = 1 Then i.PadLeft(2).ToString() ElseIf i.Count = 1 Then i.PadLeft(1).ToString() End If Next End Sub
