VB.NET在新行中拆分(C#转换) [英] VB.NET split on new lines (C# conversion)

问题描述

我正在尝试将此代码从C#转换为VB.NET

I'm trying to convert this code from C# to VB.NET

string[] lines = theText.Split(new string[] { "\r\n", "\n" }, StringSplitOptions.None);

这就是我所拥有的，问题是它正在打印消息框中的整个文本框内容，而不是打印每一行.

Here's what I have, the problem is it is printing the whole of the text box contents in the messagebox, instead of each line.

    Dim Excluded() As String

    Dim arg() As String = {"\r\n", "\n"}

    Excluded = txtExclude.Text.Split(arg, StringSplitOptions.None)

    For i As Integer = 0 To Excluded.GetUpperBound(0)
        MessageBox.Show("'" & Excluded(i) & "'")
    Next

推荐答案

就字符串文字而言，VB .Net中实际上并不存在转义序列.

Escape sequences don't really exist in VB .Net as far as string literals are concerned.

您可以使用2个特殊常量代替:

There are 2 special constants which you can use instead:

vbCrLf
vbLf

Dim Excluded() As String

Dim arg() As String = {vbCrLf, vbLf}

Excluded = txtExclude.Text.Split(arg, StringSplitOptions.None)

For i As Integer = 0 To Excluded.GetUpperBound(0)
    MessageBox.Show("'" & Excluded(i) & "'")
Next

应该做到这一点(虽然没有被试用).

Should do the trick (untested though).
