如何用c#中的某些特殊字符替换字符串中的空格以外的空格？

我有一个字符串

Hi I  am new  here. Would   you    please help    me?

我希望输出为

Hi I$am new$here. Would$you$please help$me?

我试过了

string line=@"Hi I  am new  here. Would   you    please help    me?";
string line1 = Regex.Replace(line,@"[\s\s]+","$");
Console.WriteLine(line1);

但我得到了输出

Hi$I$am$new$here.$Would$you$please$help$me?

你能告诉我我哪里错了吗？
