關于博客

以后不說話,只貼代碼和看到的鏈接,當個備忘錄吧.另外,我已近一年沒有接觸java。所以,貼的代碼和鏈接大多是關于asp.net的。BlogJava - 專注于Java技術，看到這個標題我總很慚愧,專注于Java技術,我在這里貼c#代碼..雖然博客園我也有申請博客,但和blogjava呆的時間相對比較長,也算有點感情,我也懶的搬，以后發布隨筆的時候盡量不發布到blogjava隨筆分類上。希望不會影響到blogjava的質量.

-----

我發布隨筆是用windows live writer，所以一下發個10幾篇上來。同志們不要覺得我很瘋狂。很多隨筆都是我以前的筆記和摘抄.

驗證數據庫鏈接字符串

當我正要找的時候，竟然就讓我碰到了下面這段代碼。運氣不錯

/// <summary>

/// Checks a connection string for validity

/// </summary>

/// <param name="cn">SQL Connection string to validate</param>

/// <returns>True if connection is valid.</returns>

/// <history>

///     [Tim Hibbard]   12/03/2006  Created

/// </history>

public static bool IsValidSQLConnectionString(string cn)

    bool RV = true;

try

        if (!cn.Contains("Data Source"))

            throw new MissingMemberException("Missing Data Source");

        if (!cn.Contains("Initial Catalog"))

            throw new MissingMemberException("Missing Initial Catalog");

        if (!cn.Contains("User ID"))

            throw new MissingMemberException("Missing User ID");

        if (!cn.Contains("Password"))

            throw new MissingMemberException("Missing Password");

        string[] contents = cn.Split(char.Parse(";"));

        if (!contents[0].StartsWith("Data Source"))

            throw new MissingMemberException("Missing Data Source");

        if (!contents[1].StartsWith("Initial Catalog"))

            throw new MissingMemberException("Missing Initial Catalog");

        if (!contents[2].StartsWith("User ID"))

            throw new MissingMemberException("Missing User ID");

        if (!contents[3].StartsWith("Password"))

            throw new MissingMemberException("Missing Password");

    catch (Exception)

        RV = false;

    return RV;

Nhibernate MultiQuery

構造多個查詢。效果不錯。注意Nhibernate CreateMultiQuery()這個方法

public void MultiQueryTest(int var)
{

   ISession session = null;
   session = Class1.GetFactory().OpenSession();
   IList result = session.CreateMultiQuery().Add("from Archives where id>:id")
      .Add("select count(*) from Archives a where id>:id").SetInt32("id", var).List();
   //獲得第一個查詢結果
   IList archives = (IList)result[0];
   long count = (long)((IList)result[1])[0];

   //當然也可以session.CreateQuery 構造查詢
    //IList result = session.CreateMultiQuery()
     //    .Add(session.CreateQuery("from Archives where id>:id").SetFirstResult(5).SetMaxResults(10))
    //    .Add(session.CreateQuery("select count(*) from Archives a where id>:id"))
    //    .SetCacheable(true).SetInt32("id", var).List();
    // IList archives = (IList)result[0];
   //long count = (long)((IList)result[1])[0];

 }

//helper

public class Class1

        private static ISessionFactory factory;

        private static string _mappingAssembly;

        static Class1()

            _mappingAssembly = ConfigurationManager.AppSettings["EntityAssemblyName"];

            NHibernate.Cfg.Configuration cfg = new NHibernate.Cfg.Configuration();

            foreach (string assembly in _mappingAssembly.Split(','))

try

                    cfg.AddAssembly(assembly);

                catch (MappingException me)

                    throw new MappingException("Assembley Could Not Be Loaded: " + assembly, me);

            factory = cfg.BuildSessionFactory();

        public static ISessionFactory GetFactory()

            return factory;
