我有以下方法从文件名替换"磅"符号,但我也希望能够同时替换"单撇号".我该怎么做？这是filename = Provider license_A'R_Ab#acus Settlements_1-11-09.xls的值

static string removeBadCharPound(string filename)
{            // Replace invalid characters with "_" char.            
    //I want something like this but is NOT working 
    //return Regex.Replace(filename, "# ' ", "_");
    return Regex.Replace(filename, "#", "_");
 }
