一步一步 WordCount 示例

        1. 新建一个控制台应用程序(其它类型均可)。
        2. 添加引用Iveely.CloudComputing.Client.exe。
        3. 继承Application类，重写Run()方法。
` public class MyWordCount : Application { public override void Run(object[] args) { //0.先初始化 this.Init(args);

        //1.虚拟数据构建
        string[] contents =
        {
            "This is Iveely Computing",
            "Weclome here",
            "Iveely is I void every thing,except love",
            "Thanks,Iveely Team."
        };
        StringBuilder dataBuilder = new StringBuilder();
        for (int i = 0; i < 1000; i++)
        {
            Random random = new Random(i);
            int index = random.Next(0, 4);
            dataBuilder.AppendLine(contents[index]);
        }

        string[] words = dataBuilder.ToString().Split(new[] { ' ', ',', '\r', '\n' }, StringSplitOptions.RemoveEmptyEntries);
        WriteToConsole("local words count:" + words.Length);
        int globalWordCount = Mathematics.Sum<int>(words.Length);
        WriteToConsole("global words count:" + globalWordCount);

        //2.子节点处理数据
        Hashtable table = new Hashtable();
        foreach (string word in words)
        {
            if (table.ContainsKey(word))
            {
                table[word] = int.Parse(table[word].ToString()) + 1;
            }
            else
            {
                table.Add(word, 1);
            }
        }

        //3.归并所有结点处理结果
        WriteToConsole("local word frequency count:" + table.Keys.Count);
        table = Mathematics.CombineTable(table, args);
        WriteToConsole("global word frequency count:" + table.Keys.Count);

        //4.写入文件
        StringBuilder builder = new StringBuilder();
        foreach (DictionaryEntry dictionaryEntry in table)
        {
            builder.AppendLine(dictionaryEntry.Key + " " + dictionaryEntry.Value);
        }
        WriteText(builder.ToString(), "WordCount.result", true);
    }
}`

        4. 提交自己的程序。
        5. 查看运行结果。
