如何在 string.replace 上使用字符串插值

Question

I created a method and would like to know how to use string interpolation with string.replace inside my method.

I looked through several how to's on Stack Overflow on its use but not with replace. I would like some guidance on how to accomplish this.

 private string CheckForEscapeStringInQuotesAndTrim(string csvDataValue)
 {
     if (Regex.IsMatch(csvDataValue, "[,\"\\r\\n]"))
     {
         return "\"" + csvDataValue.Replace("\"", "\"\"") + "\"";
     }
     //trim any unnecessary whitespace
     return csvDataValue.Trim();
 }

You could simply use csvDataValue.Replace("\\"", "\\"\\"") as an interpolated expression it will be resolved.

private string CheckForEscapeStringInQuotesAndTrim(string csvDataValue)
{
    if (Regex.IsMatch(csvDataValue, "[,\"\\r\\n]"))
    {
        return $"\"{csvDataValue.Replace("\"", "\"\"")}\"";
    }
    //trim any unnecessary whitespace
    return csvDataValue.Trim();
}
