VB.Net 的下一个目标

Question

这两者有区别吗？

For i = 0 To Something.Length - 1
  'do something
Next

For i = 0 To Something.Length - 1
  'do something
Next i

Answer 1

这只是为了可读性:

You can optionally specify counter in the Next statement. This improves the readability of your program, especially if you have nested For loops. You must specify the same variable as the one that appears in the corresponding For statement.
