问题描述

我正在学习C＃并发现将此JAVA代码转换为C＃的困难。如果有人提供解决方案。对我的理解会更好。

I'm learning C# and finding difficulties in converting this JAVA code into C#. If anyone would provide a solution. Would be better for my understanding.

public static List<Operator> oprs = new List<Operator>();
private List<String> GetTokens(String s)
    {
        StringBuilder sb = new StringBuilder();
        sb.Append(Pattern.quote(oprs[0].symbol));

        for (int i = 1; i < oprs.Count; i++)
        {
            sb.Append("|");
            sb.Append(Pattern.quote(oprs.get(i).symbol));
        }
        sb.Append("|[a-zA-Z_]+[a-zA-Z0-9_]*\\([^()]*\\)|[0-9]+|[a-zA-Z_][a-zA-Z0-9_]*|\\Q(\\E|\\Q)\\E");

        List<String> tokens = new List<String>();
        Pattern p = Pattern.compile(sb.ToString());
        Matcher m = p.matcher(s);

        while (m.find()) tokens.add(m.group());
        return tokens;
    }

What I have tried:

Try 1

public static List<operator> oprs = new List<operator>();
private List<string> GetTokens(String s)
    {
Dictionary<string,> dictionary = new Dictionary<string,>()
            {
                {source, " " }
            };
            var matches = dictionary.SelectMany(a => Regex.Matches(s, a.Value)
            .Cast<match>()
            .Select(b=>
                    new
                    {
                        Index = b.Index,
                        Value = b.Value,
                        Token = a.Key
                    }))
            .OrderBy(a => a.Value).ToList();
            List<string> tokens = new List<string>();
            foreach(var items in matches)
            {
                tokens.Add(items.Value.ToString());
            }
return tokens;
}

Try 2

private List GetTokens(String s)
{
    List tokens = new List();
    Regex rx = new Regex(@"|[a-zA-Z_]+[a-zA-Z0-9_]*\\([^()]*\\)|[0-9]+|[a-zA-Z_][a-zA-Z0-9_]*|\\Q(\\E|\\Q)\\E");

    MatchCollection matches = rx.Matches(s);
    if (matches.Count > 0)
    {
        Match match = matches[0];
        GroupCollection groupCollection = match.Groups;
    }

    foreach(var ma in matches)
    {
        tokens.Add(ma.ToString());
    }

    return tokens;
}

推荐答案

如何使用其中一个转换器，然后研究并调整结果？

请注意，varycode目前正在更新java算法，并且在线无法使用。





微软还提供此功能



[在VS中（参见MSDN）]

How about you use one of the converters and then study and tweak the result?

Note that varycode is currently updating java algorithm and is unavailable online.


Microsoft also provides this functionality

[in VS (see MSDN)]
