vba string转integer

将VBA字符串转换为整数可以使用VBA内置函数Val(),例如:
Dim str As String
Dim num As Integer
str = "123"
num = Val(str)
这将把字符串"123"转换为整数123并保存在变量num中。

vba excel转txt
你可以使用 VBA 代码将 Excel 文件转换为文本文件。以下是一个示例代码:
```vb
Sub ExportToTextFile()
Dim myFile As String
Dim rng As Range
Dim cellValue As Variant
Dim i As Integer, j As Integer
'Get file name
myFile = Application.GetSaveAsFilename(fileFilter:="Text Files (*.txt), *.txt")
'Exit if user cancels
If myFile = "" Then Exit Sub
'Open file for output
Open myFile For Output As #1
'Loop through each row and column in the range
For i = 1 To ActiveSheet.UsedRange.Rows.Count
For j = 1 To ActiveSheet.UsedRange.Columns.Count
'Get cell value
cellValue = ActiveSheet.Cells(i, j).Value
'Write cell value to file
If j = ActiveSheet.UsedRange.Columns.Count Then
Write #1, cellValue
Else
Write #1, cellValue,
End If
Next j
Next i
'Close file
Close #1
MsgBox "Export complete."
End Sub
```
在运行代码之前,请确保你已经保存了 Excel 文件。该代码将提示你选择一个文本文件的保存位置。然后,它将循环遍历所选范围中的每个单元格,并将其值写入文本文件中。
vba 数组转成字符串
在VBA(Visual Basic for Applications)中,将数组转换为字符串通常可以通过循环遍历数组元素并将它们连接起来完成。这里是一个基本的方法:
```vba
Function ArrayToString(arr() As Variant) As String
Dim strResult As String
Dim i As Long
' 初始化结果字符串
strResult = ""
' 遍历数组
For i = LBound(arr) To UBound(arr)
' 将每个元素添加到结果字符串,如果元素不是字符串类型,可能需要先转换
If TypeName(arr(i)) <> "String" Then
arr(i) = CStr(arr(i)) ' 转换为字符串类型
End If
strResult = strResult & arr(i) ' 连接元素
' 如果不是最后一个元素,添加分隔符(如逗号或空格)
If i < UBound(arr) Then
strResult = strResult & ", "
End If
Next i
ArrayToString = strResult
End Function
```
你可以通过调用这个`ArrayToString`函数并传入你的数组来得到字符串形式的结果。例如:
```vba
Dim myArray(1 to 5) As Integer
myArray(1) = 1
myArray(2) = 2
' ... (填充更多元素)
Dim result As String
result = ArrayToString(myArray)
Debug.Print result ' 输出:1, 2, ...
```
