如何計算vb.net中的空格和字符數？

Question

我想計算在文本框字段中輸入的空格和字符數。 實施例

textbox1.text - " 1 2 3 4 5 6 7 a b c" 

我要計數的空格數和字符

然後其結果必然是..

昏暗空格作爲整數，焦炭用作整數

空間= 10 ，char = 10

Answer 1

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 Each將迭代string中的每個字符，然後它將檢查c是否爲空格。如果是空格，則增加spaceCount，否則增加lettrtCount

Answer 2

您可以按照您的需要按排序方式進行操作。

嘗試

Dim count As Integer = 0 
textbox1.text = " 1 2 3 4 5 6 7 a b c" 
count = textbox1.text.Split(" ").Length -1 

Answer 3

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)
