Answer 1

给你写一个现成的方法

        public static string ReplaceFirstStr(string sourceStr, string splitStr, string newStr)
        {
            try
            {
                int indexOfFirstSplitStr = sourceStr.IndexOf(splitStr);
                StringBuilder sb = new StringBuilder(sourceStr);
                sb.Replace(splitStr, newStr, indexOfFirstSplitStr, splitStr.Length);
                sourceStr = sb.ToString();
            }
            catch
            { }
            return sourceStr;
        }
