Then the result must be..
那么结果一定是..
Dim spaces as integer, char as integer
Dim 空格为整数，char 为整数
spaces = 10 , char = 10
空格 = 10 ，字符 = 10

Dim spaceCount, lettercount As Integer
spaceCount= 0
lettercount = 0
Dim s As String = " 1 2 3 4 5 6 7 a b c"
For Each c As Char In s
If c = " " Then
spaceCount+= 1
Else
lettercount += 1
End If
Next
MsgBox(charcount)
MsgBox(lettercount)
For Eachwill iterate each character within the stringthen it will check whether cis a space or not. if it is a space then increment the spaceCountelse increment the lettrtCount
For Each将迭代每个字符，string然后它会检查是否c是一个空格。如果它是一个空格然后增加spaceCountelse 增加lettrtCount

You can do as you want in a sort way.
您可以以某种方式为所欲为。
Try it
尝试一下
Dim count As Integer = 0
textbox1.text = " 1 2 3 4 5 6 7 a b c"
count = textbox1.text.Split(" ").Length -1

Dim longstring As String = "aab c d e"
Dim TotalLength As Integer = longstring.Length
Dim TotalSpaces() As String = Split(longstring, " "
Dim TotalChars As Integer = TotalLength - (TotalSpaces.Length - 1)
