使用C＃生成Powershell脚本时转义字符

Question

我使用VS2010，C＃，.NET 3.5生成Powershell脚本（ps1文件）。

然后，Powershell需要转义字符。

有关它的任何建议用于开发转义字符的良好方法？

public static partial class StringExtensions 
    { 
     /* 
     PowerShell Special Escape Sequences 

     Escape Sequence   Special Character 
     `n      New line 
     `r      Carriage Return 
     `t      Tab 
     `a      Alert 
     `b      Backspace 
     `"      Double Quote 
     `'      Single Quote 
     ``      Back Quote 
     `0      Null 
     */ 

     public static string FormatStringValueForPS(this string value) 
     { 
      if (value == null) return value; 
      return value.Replace("\"", "`\"").Replace("'", "`'"); 
     } 
    } 

用法：

var valueForPs1 = FormatStringValueForPS("My text with \"double quotes\". More Text"); 
var psString = "$value = \"" + valueForPs1 + "\";";

另一种选择是使用正则表达式：

private static Regex CharactersToEscape = new Regex(@"['""]"); // Extend the character set as requird 


public string EscapeForPowerShell(string input) { 
    // $& is the characters that were matched 
    return CharactersToEscape.Replace(input, "`$&"); 
} 

注意：你不需要逃避反斜杠：PowerShell不把它们作为转义字符。这使得编写正则表达式更容易一些。
