(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();
        }
