C＃替換字符串「與」

Question

我有這個字符串波紋管

string b = IIF("L" = "H", 9.0, IIF("L" = "M", 7.5, 6.0)) 

，我想用'L'與'H'和"L"更換"H"

我嘗試這樣做，它不工作：

b = b.Replace("\"", "'"); 

它給我這個錯誤：

SyntaxError: missing) after argument list

這個作品

  string b = "IIF(\"L\" = \"H\", 9.0, IIF(\"L\" = \"M\", 7.5, 6.0)"; 
      b = b.Replace("\"", "'");

玩這個在.NET小提琴（https://dotnetfiddle.net/）：

using System; 

public class Program 
{ 
    public static void Main() 
    { 
     var test = "This is \"a\" string"; 

     Console.WriteLine(test); 

     test = test.Replace('\"', '\''); 

     Console.WriteLine(test); 
    } 
}
