推荐答案

尝试此

try this

For i As Integer = 0 To str.Length - 1
    If i = 3 Then
        str = str.Insert(i, " ")
    End If
Next

如果字符串包含数字，我认为最简单的方法是首先将其强制转换为例如整数( http://msdn.microsoft.com对其进行格式化/en-us/library/ms157406(v=SQL.100).aspx [

If the string contains numbers, I think the easiest way is to cast it first to for example integer (http://msdn.microsoft.com/en-us/library/ms141704.aspx[^])

And then format it using number format models http://msdn.microsoft.com/en-us/library/ms157406(v=SQL.100).aspx[^]
