(C#) 字符串替换

(C#) 字符串替换

1. 少的话，直接使用 String.Replace

例如： 

        // Correct the spelling of "document".



        string correctString = errString.Replace("docment", "document");

 

2. 多的话，建个处理方法

        private static string FomatName(string name)

        {

            var replacements = new Dictionary<char, char>() {

                {'/', '_'},

                {' ', '_'}

                {'.', '_'}

                {'-', '_'}

            };



            StringBuilder sb = new StringBuilder();

            foreach (char ch in name)

            {

                char replaced;

                if (replacements.TryGetValue(ch, out replaced))

                {

                    sb.Append(replaced);

                }

                else

                {

                    sb.Append(ch);

                }

            }



            return sb.ToString();

        }
