如何解析這個逗號分隔的字符串？

Question

我有以下字符串：

"'2014' , '381' , '1' , 'Eastern 10' , 'Wes 10' , '1'" 

我想加盟位置1和2一起，將它保存到正確位置1，例如：

"'2014381' , '381' , '1' , 'Eastern 10' , 'Wes 10' , '1'" 

Answer 1

var str = "'2014' , '381' , '1' , 'Eastern 10' , 'Wes 10' , '1'"; 
var parts = str.Split(new string[] { " , " }, StringSplitOptions.None); 

parts[0] = String.Format("'{0}{1}'", parts[0].Replace("'", ""), 
            parts[1].Replace("'", "")); 
str = String.Join(" , ", parts); 

Answer 2

使用replaceFirst功能在此指出的問題：

How do I replace the *first instance* of a string in .NET?

string ReplaceFirst(string text, string search, string replace) 
{ 
    int pos = text.IndexOf(search); 
    if (pos < 0) 
    { 
    return text; 
    } 
    return text.Substring(0, pos) + replace + text.Substring(pos + search.Length); 
} 

你可以再做：

string updated = ReplaceFirst(original, "' , '", ""); 

Answer 3

使用String.Split和String.Join：

string text = "'2014' , '381' , '1' , 'Eastern 10' , 'Wes 10' , '1'"; 
string[] words = text.Split(new[] { "' , '" }, StringSplitOptions.None); 
string result = string.Join("", words.Take(2)) + 
       string.Join("' , '", words);

Answer 4

var input = "'2014' , '381' , '1' , 'Eastern 10' , 'Wes 10' , '1'"; 
var delimeter = " , "; 

var splits = input.Split(',').Select (i => i.Trim()); 
var result = splits.Take(2).Aggregate ((x, y) => x + y).Replace("''", "") 
    + delimeter + splits.Skip(1).Aggregate ((x, y) => x + delimeter + y); 

輸出：

'2014381' , '381' , '1' , 'Eastern 10' , 'Wes 10' , '1'
