请教1个字符串处理的问题

[xxmiaoyong126com]

字符串：M100505745662118,M100506254172546,M100506751910768
处理后变成
字符串：'M100505745662118','M100506254172546','M100506751910768'

","号个数不固定的

数据库子查询需要用到这种格式

先Split成数组，再用StringBuilder拼接

string str = "M100505745662118,M100506254172546,M100506751910768";
str = "'" + str + "'";
str = str.Replace(",","','")

经典

[wackyboy]

string input = "M100505745662118,M100506254172546,M100506751910768";
string output = Regex.Replace(input, @"\b", "'");

System.Text.StringBuilder sb = new System.Text.StringBuilder();
string str = "M100505745662118,M100506254172546,M100506751910768";
string[] strs = str .Split(',');
for (int i = 0; i < strs .Length; i++)
                    {
                        sb.Append("'");
                        sb.Append(strs[i]);
                        sb.Append("'");
                        if (strs1.Length - 1 != i)
                            sb.Append(",");
                    }
