C＃：將圖形代碼合併到一起？

Question

我有一個數字代碼，可以檢測用戶穿着什麼衣服。以下是一些隨機數字代碼的例子。

lg-285-76.hr-155-31.sh-300-92.ca-1819-63.hd-209-2.ch-3030-76. 
he-3149-1331.sh-3035-110.hr-170-61.fa-3276-72.ch-255-110.hd-209-2.lg-280-1331. 
ch-210-110.hd-209-7.hr-828-1407.he-3082-63.lg-280-1408.cp-3309-77.sh-290-92. 

的雙字母代碼指示衣服的類型，例如：

• lg =腿
• ch =胸部
• sh =鞋
• he =頭
• hr =頭髮

我想要做的就是將該數字代碼與統一代碼合併。可以說，我有一個統一的代碼，我想圖形代碼合併，並且這件制服包含一件t恤和褲子。它將包含腿部的lg標籤和胸部的ch標籤。

統一字符串：lg-285-76.sh-300-92.ch-3030-76.

我想要做的就是更換腿部，胸部等在主圖形碼，並與一個在統一的字符串替換它們，這裏是我到目前爲止已經試過：

public static string ReturnUniform(string uniform, string figure) 
{ 
    string[] uniformParts = uniform.Split('.'); 
    string[] figureParts = uniform.Split('.'); 

    foreach (string uniformPart in uniformParts) 
    { 
     string[] childUniformParts = uniformPart.Split('-'); 

     if (figure.Contains("." + childUniformParts[0])) 
     { 
      // remove it from figure parts and replace it with the uniform one here 
     } 
    } 

    return string.Join("", figureParts); 
}

我建議使用的LINQ和正則表達式（解析各行）：

string[] figures = new string[] { 
    "lg-285-76.hr-155-31.sh-300-92.ca-1819-63.hd-209-2.ch-3030-76.", 
    "he-3149-1331.sh-3035-110.hr-170-61.fa-3276-72.ch-255-110.hd-209-2.lg-280-1331.", 
    "ch-210-110.hd-209-7.hr-828-1407.he-3082-63.lg-280-1408.cp-3309-77.sh-290-92.", 
    }; 

    // we want "lg", "sh", "ch" in this particular order 
    string[] itemsToGet = new string[] { "lg", "sh", "ch" }; 

    var result = figures 
    .Select(figure => Regex 
     // Parse each line into name (e.g. "sh") 
     //      value (e.g. "3035-110") 
     //      index in the itemsToGet (-1 if absent) 
     // with a help of regular expression 
     .Matches(figure, @"(?<name>[a-z]+)-(?<value>[0-9]+-[0-9]+)\.") 
     .OfType<Match>() 
     .Select(match => new { 
     name = match.Groups["name"].Value, 
     value = match.Groups["value"].Value, 
     index = Array.IndexOf(itemsToGet, match.Groups["name"].Value) }) 
     // we want items' names that are presented in itemsToGet only... 
     .Where(item => item.index >= 0) 
     // ... and in the right order (as they mentioned in itemsToGet) 
     .OrderBy(item => item.index) 
     // item format: "name.value." 
     // $"..." (string interpolation) is a C# 6.0 syntax; C# 5.0- alternative 
     // .Select(item => string.Format("{0}.{1}.", item.name, item.value)) 
     .Select(item => $"{item.name}.{item.value}.")) 
    // concat all the items back into a string e.g. "lg.285-76.sh.300-92.ch.3030-76." 
    .Select(items => string.Concat(items)) 
    // finally, let's materialize records into an array 
    .ToArray(); 

測試：

Console.Write(string.Join(Environment.NewLine, result)); 

結果（提取itemsToGet名，爲了保存）：

lg.285-76.sh.300-92.ch.3030-76. 
lg.280-1331.sh.3035-110.ch.255-110. 
lg.280-1408.sh.290-92.ch.210-110.
