在文本文件 vb.net 中写多行带引号

Question

嗨，有没有更简单的方法可以在包含引号和其他类似内容的文件中写入多行，或者这是这样做的唯一方法

                Dim objwriter As New System.IO.StreamWriter(AppsDir & "EthIPChanger.bat")
            objwriter.WriteLine("@echo off")
            objwriter.WriteLine("netsh interface ip set address name=""" & "Local Area Connection""" & " static " & TB_EthIPAddress.Text & " " & TB_EthSubnetMask.Text & " " & TB_EthDefaultGateway.Text & " 1")
            objwriter.WriteLine("netsh interface ip set dns """ & "Local Area Connection""" & " static " & TB_EthDNS1.Text)
            objwriter.WriteLine("ipconfig /all > """ & AppsDir & "NetworkInfo.txt""")
            objwriter.WriteLine("echo hi > """ & AppsDir & "CheckLen.txt""")
            objwriter.Close()

我知道如果你使用的是python，你可以做""，

然后在里面做任何事情，并以"结尾

vb.net 存在这样的事情吗？

谢谢

如果你使用objwriter。写入 - 然后您可以自己提供 vbcrlf - 然后您可以在一个写入语句中放置多个"行"。

例如：

Dim str2write As string
str2write  = "firstline" and Chr(34) & Chr(34) & vbcrlf
str2write &= Chr(34) & "second line" and Chr(34) & vbcrlf & vbcrlf
objwriter.write(str2write)
objwriter.close()

你可以尝试使用StringBuilder：

    Dim objwriter As New System.IO.StreamWriter(AppsDir & "EthIPChanger.bat")
    Dim textToWrite As New System.Text.StringBuilder
    With textToWrite
        .Append("@echo off")
        .AppendFormat("netsh interface ip set address name={0}Local Area Connection{0} static {1} {2} {3} 1", Chr(34), TB_EthIPAddress.Text, TB_EthSubnetMask.Text, TB_EthDefaultGateway.Text)
        .AppendFormat("netsh interface ip set dns {0}Local Area Connection{0} static {1}", Chr(34), TB_EthDNS1.Text)
        .AppendFormat("ipconfig /all > {0}{1}{2}{0}", Chr(34), AppsDir, TB_EthDNS1.Text)
        .AppendFormat("echo hi > {0}{1}{2}{0}", Chr(34), AppsDir, CheckLen.Text)
    End With
    objwriter.WriteLine(textToWrite.ToString)
    objwriter.Close()
