威力强大的 DateTime.ParseExact

http://www.cnblogs.com/panzhilei/archive/2007/05/24/758595.aspx
统一项目时间格式（DateTime.ParseExact使用）

string   year   =   "2005";
                                string   mon   =   "05";
                                string   day   =   year   +   "-"   +   mon;
                                DateTime   date   =   DateTime.ParseExact(   day,   "yyyy-mm",   CultureInfo.CurrentCulture   );  

    从文本文件中读入数据时，遇到 "20061230" 这种日期格式，用C#的Convert.ToDateTime(string)方法，是不能进行转换的。查看了一下DateTime结构，发现ParseExact方法可以转化成DateTime结构，把代码贴在这里：

string dt = "20061230";                                                                                                                                                

DateTimeFormatInfo info1 = (DateTimeFormatInfo) Thread.CurrentThread.CurrentCulture.GetFormat(typeof(DateTimeFormatInfo));
DateTime time1 = DateTime.ParseExact(dt,"yyyyMMdd", info1, DateTimeStyles.AllowWhiteSpaces);

Console.WriteLine(time1 );

其中第二个参数格式数组，写了几个：

new string[] { "MMM d yyyy hh:mm:ss:ffftt", "MMM d yyyy hh:mm:ss:fff", "d MMM yyyy hh:mm:ss:ffftt", "d MMM yyyy hh:mm:ss:fff", "hh:mm:ss:ffftt", "hh:mm:ss:fff", "yyMMdd", "yyyyMMdd" };

用StructLayout特性限定声明结构或类

using System;
using System.Runtime.InteropServices;
using System.Text;

class Class1
{

    [StructLayout(LayoutKind.Sequential, CharSet=CharSet.Unicode)]
    public struct MyStruct
    {
        [MarshalAs(UnmanagedType.ByValTStr, SizeConst=4)] public string fname;
        [MarshalAs(UnmanagedType.ByValTStr, SizeConst=4)] public string lname;
        [MarshalAs(UnmanagedType.ByValTStr, SizeConst=7)] public string phone;
    }
   
    public static void Main()
    {
        string buffer = "abcdefgh2223333";
        IntPtr pBuf = Marshal.StringToBSTR(buffer);
        MyStruct ms = (MyStruct)Marshal.PtrToStructure(pBuf,typeof(MyStruct));
        Console.WriteLine("fname is: { 0 }",ms.fname);
        Console.WriteLine("lname is: { 0 }",ms.lname);
        Console.WriteLine("phone is: { 0 }",ms.phone);
        Marshal.FreeBSTR(pBuf);
    }
}

System.Configuration.Configuration rootWebConfig =
    System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration("/MyWebSiteRoot");
System.Configuration.ConnectionStringSettings connString;
if (0 < rootWebConfig.ConnectionStrings.ConnectionStrings.Count)
{
    connString =
        rootWebConfig.ConnectionStrings.ConnectionStrings["NorthwindConnectionString"];
    if (null != connString)
        Console.WriteLine("Northwind connection string = \"{ 0 }\"",
            connString.ConnectionString);
    else
        Console.WriteLine("No Northwind connection string");
}

C# 通过类名动态创建对象

加载程序集有两个函数，Assembly.Load()和Assembly.LoadFrom()。Assembly.Load的参数是程序集的名称，运行库会在本地目录和全局程序集高速缓存内搜索该程序集；Assembly.LoadFrom()的参数是程序集的完成路径名，不会在其它位置搜索该程序集。
