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。
