vb.net合并空格 vb excel 合并单元格

VB.net 中，输入“空格”的代码textbox.text = "12345"" ""67890"
或者
textbox.text = "12345"space(1)"67890"
vb.net 在TextBox1中输入数字和空格，并求奇数数字，并求和给你个参考的例子
Imports System.Text.RegularExpressions
Public Class Form1
Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged
Dim a_point As Integer = TextBox1.SelectionStart
Dim bs As String = Regex.Replace(TextBox1.Text, "[^ \d]", "")
If TextBox1.TextLengthbs.Length Then
TextBox1.Text = bs
TextBox1.SelectionStart = a_point
End If
End Sub
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim gs() As String = (From mt As Match In Regex.Matches(TextBox1.Text, "\d*[13579]\b") Select mt.Value).ToArray
TextBox2.Lines = gs
TextBox3.Text = ((From mt As String In gs Select CInt(mt)).ToArray).Sum
End Sub
End Class
vb.net 中两个string()合并Dim Str1() As String = {"123", "321", "231", "132"}
Dim Str2() As String = {"qwe", "asd", "zxc", "sdf", "asdf"}
Dim Str() As String = Str1
ReDim Preserve Str(Str1.Length + Str2.Length - 1)
Str2.CopyTo(Str, Str1.Length)
