Bing 與 Google 是常用的搜尋引擎，而 Bing 與 Google 分別有 Bing API 與 Google Web API 可以讓程式獲取搜尋結果，

本文實做行動裝置應用程式，功能為取得 Bing 與 Google 搜尋的結果。

Bing

2. 方法

2.1 使用 Bing API

(1) 申請 AppID

網址 http://www.bing.com/developers/default.aspx，使用 Live Passport 登入，並輸入相關資訊，註冊後得到一組 AppID

(2) 加入 Web 參考

在 [URL] 中輸入 http://api.search.live.net/search.wsdl?AppID=申請的AppID，修改 [Web 參考名稱]，點選 [加入參考]

在程式中 using 專案名稱.參考名稱

using SmartDeviceSearch.net.live.search.api;

(3) 程式碼

        #region Bing API
        private void btnBing_Click(object sender, EventArgs e)
        {
            // LiveSearchService implements IDisposable.
            using (LiveSearchService service = new LiveSearchService())
            {
                try
                {
                    SearchRequest request = BuildRequestWeb();

                    // Send the request; display the response.
                    SearchResponse response = service.Search(request);
                    DisplayResponseWeb(response);
                }
                catch (System.Net.WebException ex)
                {
                    // An exception occurred while accessing the network.
                    Console.WriteLine(ex.Message);
                }
            }
        }

        private SearchRequest BuildRequestWeb()
        {
            SearchRequest request = new SearchRequest();

            // Common request fields (required)
            request.AppId = "B692A148D1624C4E3C1248C8E5DDC209E524D2C4";
            request.Query = this.txtQuery.Text;
            request.Sources = new SourceType[] { SourceType.Web };

            // Common request fields (optional)
            request.Version = "2.0";
            request.Market = "zh-tw";
            request.Adult = AdultOption.Moderate;
            request.AdultSpecified = true;
            request.Options = new SearchOption[]
            {
                SearchOption.EnableHighlighting
            };

            // Web-specific request fields (optional)
            request.Web = new WebRequest();
            request.Web.Count = 10;
            request.Web.CountSpecified = true;
            request.Web.Offset = 0;
            request.Web.OffsetSpecified = true;
            request.Web.Options = new WebSearchOption[]
            {
                WebSearchOption.DisableHostCollapsing,
                WebSearchOption.DisableQueryAlterations
            };
            return request;
        }

        private void DisplayResponseWeb(SearchResponse response)
        {
            // Display the results header.
            string strHeader = "";
            strHeader += "Bing API" + System.Environment.NewLine;
            strHeader += "Results Count : " + response.Web.Total;
            this.labBing.Text = strHeader;

            DataTable Table_Results = new DataTable();
            Table_Results.Columns.Add(new DataColumn("Title", typeof(string)));
            Table_Results.Columns.Add(new DataColumn("Description", typeof(string)));
            Table_Results.Columns.Add(new DataColumn("link", typeof(string)));

            // Display the Web results.
            foreach (WebResult result in response.Web.Results)
            {
                DataRow row = Table_Results.NewRow();
                row[0] = result.Title;
                row[1] = result.Description;
                row[2] = result.Url;
                Table_Results.Rows.Add(row);
            }
            this.dataGridBing.DataSource = Table_Results;
        }
        #endregion

2.2 使用 Google API

(1) 加入 Web 參考

在 [URL] 中輸入 http://api.google.com/GoogleSearch.wsdl，修改 [Web 參考名稱]，點選 [加入參考]

在程式中 using 專案名稱.參考名稱

using SmartDeviceSearch.com.google.api;

(2) 程式碼

#region Google API
private void btnGoogle_Click(object sender, EventArgs e)
{
    // GoogleSearchService implements IDisposable.
    GoogleSearchService service_google = new GoogleSearchService();
    GoogleSearchResult result = service_google.doGoogleSearch("a5/RXzlQFHKb8PhlejS5MC3nRkK6ngot", this.txtQuery.Text, 0, 10, false, "", true, "lang_zh-TW", "", "");

    // Display the results header.
    string strHeader = "";
    strHeader += "Google API" + System.Environment.NewLine;
    strHeader += "Results Count : " + result.estimatedTotalResultsCount;
    this.labGoogle.Text = strHeader;

    // Display the Web results.
	DataTable Table_Results = new DataTable();
	Table_Results.Columns.Add(new DataColumn("Title", typeof(string)));
	Table_Results.Columns.Add(new DataColumn("Description", typeof(string)));
	Table_Results.Columns.Add(new DataColumn("link", typeof(string)));

    for (int i = 0; i < result.resultElements.Length; i++)
	{
		DataRow row = Table_Results.NewRow();
        row[0] = result.resultElements[i].title;
        row[1] = result.resultElements[i].snippet;
        row[2] = result.resultElements[i].URL;
		Table_Results.Rows.Add(row);
	}
    this.dataGridGoogle.DataSource = Table_Results;
}
#endregion
