VB.NET拆分新行（C＃轉換）

Question

我正在嘗試將此代碼從C＃轉換為VB.NET

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

這就是我所擁有的，問題是它是在消息框中打印整個文本框內容，而不是每行。

    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

Answer 1

您不能使用反斜杠（ \\ ）來轉義VB中的字符。 使用ControlChars類：

Dim arg() As String = { ControlChars.CrLf, ControlChars.Lf }

Answer 2

就字符串文字而言，轉義序列在VB .Net中並不存在。

您可以使用2個特殊常量：

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

應該做的伎倆（雖然未經測試）。

來自在線轉換器 ：

你的c＃代碼：

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

轉換為VB.NET：

Dim lines As String() = theText.Split(New String() {vbCr & vbLf, vbLf}, StringSplitOptions.None)
