不爽的VS2010总有解决办法

paulleder@msn.com(PaulLeder) — Fri,23 Jul 2010 16:46:08 +0800

开始用VS2010还是挺好的，最不爽的莫过于它的项目右键菜单，正如http://www.cnblogs.com/KevinYang/archive/2010/06/02/1749671.html文章提到的。
后来我在网上找了一些插件（VS2010的插件是要比VS2008丰富多了）来解决了种种问题。我推荐的VS2010插件如下：
AxTools.VS10X.CodeMap ---可以在代码编辑区域右侧出现代码大纲，也很容易控制代码折叠，还有历史记录功能等等。
codecompareinstall ---代码比较工具
Microsoft.VisualStudio.RegularExpression ----正则表达式帮助工具，之要你new RegExp后就会自动弹出
PowerCommands ---命令增强工具，会提供文件打开工具，项目清除多余命名空间等功能，很实用
ProPowerTools ----算是一个VS2010很男用UI部分的一个补救，用了就知道
SelectionHighlight ---选择单词后会显示当前页所有此命名的变量，没有延时出现
ThemeManagerPackage ---风格选择和自定义颜色工具。

介绍就到此，上述插件均为MS开发。地址：

VS2010引用第三方组建错误（具有依赖关系。请删除对不在目标框架中的程序集的引用，或考虑重新确定）

paulleder@msn.com(PaulLeder) — Sun,18 Jul 2010 09:49:34 +0800

log4net has a known issue of referencing a System.Web component which is not part of the .NET Framework 4 Client Profile and the VS2010 by default sets project target to be the lightweighted Client Profile. The solution is to change the target to .NET Framework 4:

Right click project -> properties -> Application. Change:

.NET Framework 4 Client Profile

to be:

.NET Framework 4

... and that should work, i.e. you can use log4net again...

通过Enum.Parse转换字符串成对应的枚举类型

paulleder@msn.com(PaulLeder) — Sun,18 Jul 2010 08:17:14 +0800

引用内容

using System;

public class ParseTest {
    [FlagsAttribute]
    enum Colors { Red = 1, Green = 2, Blue = 4, Yellow = 8 };

    public static void Main() {

        Console.WriteLine("The entries of the Colors Enum are:");
        foreach(string s in Enum.GetNames(typeof(Colors)))
            Console.WriteLine(s);

        Console.WriteLine();

        Colors myOrange = (Colors)Enum.Parse(typeof(Colors), "Red, Yellow");
        Console.WriteLine("The myOrange value has the combined entries of {0}", myOrange);
    }
}

这里需要注意：
如果写成下面结果会不一样：

引用内容

using System;

public class ParseTest {

    enum Colors { Red = 1, Green = 2, Blue = 4, Yellow = 8 };

    public static void Main() {

        Console.WriteLine("The entries of the Colors Enum are:");
        foreach(string s in Enum.GetNames(typeof(Colors)))
            Console.WriteLine(s);

        Console.WriteLine();

        Colors myOrange = (Colors)Enum.Parse(typeof(Colors), "Red, Yellow");
        Console.WriteLine("The myOrange value has the combined entries of {0}", myOrange);
    }
}

最后的结果会输出9，而前一个则会输出Red|Yellow

C#开发彩信帮助利器（MMS、SDP）

paulleder@msn.com(PaulLeder) — Wed,07 Jul 2010 16:46:42 +0800

开发彩信（MM7或基于MM7的SDP）均采用带附件的SOAP方式传输。问题难就难在传输的SOAP还要带附件。
在网上看到很多人把SOAP报文搞得很神秘，现在想回去，这些人应该是没有拿到移动运营商的协议资料才这样的。
但是即使你知道了带附件的SOAP也未必能下手处理彩信分包。这是个最关键的问题。
之前我用过SharpMIMETools,是一个不错的工具，但是因为他并不支持内嵌式的分块，所以我选择了放弃，也许它本身是支持的，只是我没有发现而已。
后来我找到了A C# Implementation of Mime De/encode解决了这样的问题，个人觉得A C# Implementation of Mime De/encode更加方便使用，当然，需要做一些简单的扩展。
比如我的例子，此例子是在原DEMO的基础上修改的。需要修改DEMO里面的MIME类。

引用内容

MimeMessage mail = new MimeMessage();
            mail.Setversion();
            mail.SetContentType("multipart/related; type=\"text/xml\"; start=\"\"");

            mail.SetBoundary(null);

            // Add a text body part
            // default Content-Type is "text/plain"
            // default Content-Transfer-Encoding is "7bit"
            MimeBody mBody = mail.CreatePart();
            //mBody.SetContentType("text/xml; charset=UTF-8");
            mBody.SetTransferEncoding("8bit");
            mBody.SetContentID("rootpart@soapui.org");
            System.Text.StringBuilder sb1 = new StringBuilder();
            sb1.AppendLine("http://schemas.xmlsoap.org/soap/envelope/\" xmlns:loc=\"http://www.csapi.org/schema/parlayx/multimedia_messaging/send/v2_4/local\">");
            sb1.AppendLine("");
            sb1.AppendLine(" ");
            sb1.AppendLine(" ");
            sb1.AppendLine("");

            mBody.SetText(sb1.ToString());

            mBody = mail.CreatePart();
            mBody.SetTransferEncoding("base64");
            mBody.SetContentType("images/jpg");
            mBody.ReadFromFile("00.jpg");
            mBody.SetContentID("001.jpg");

            //Add an embeded multipart
            mBody = mail.CreatePart();
            mBody.SetContentType("multipart/mixed");
            mBody.SetBoundary(null);

            MimeBody mBodyChild = mBody.CreatePart();
            mBodyChild.SetContentID("Part 1.txt");
            mBodyChild.ReadFromFile("a.txt");

            mBodyChild = mBody.CreatePart();
            mBodyChild.SetContentID("Part 2.txt");
            mBodyChild.SetText("Content of Part 2\r\n");


            //store content to a string buffer
            StringBuilder sb = new StringBuilder();
            mail.StoreBody(sb);

            StreamWriter sw = new StreamWriter("aaa2.txt");
            sw.Write(sb.ToString());
            sw.Close();

            StreamReader sr = new StreamReader("aaa2.txt");
            string message = sr.ReadToEnd();
            MimeMessage aMimeMessage = new MimeMessage();
            aMimeMessage.LoadBody(message);

            ArrayList bodylist = new ArrayList();
            aMimeMessage.GetBodyPartList(bodylist);
            for (int i = 0; i < bodylist.Count; i++)
            {
                MimeBody ab = (MimeBody)bodylist[i];
                if (ab.IsText())
                {
                    string m = ab.GetText();
                    System.Windows.Forms.MessageBox.Show(m);
                }
                else if (ab.IsAttachment())
                {
                    ab.WriteToFile("new" + ab.GetContentID());
                }
            }

例子中需要一张命名为00.jpg的图片，不然会报错的，需要扩展Content_ID等。在原DEMO上是会出错的。
最后的结果是：

工作机理就是线程1给其中一个Queue1推新数据，当Queue1满了，则线程1给Queue2填充数据，而线程二开始将Queue1的数据推出，交替使用Queue

.NET 2.0是通过委托实现，.NET 3.0以上是用LINQ,LINQ其实也就是一种特殊的委托。所以LINQ总是会有延时。

正则表达式匹配可能带有小数点的数字

paulleder@msn.com(PaulLeder) — Thu,17 Jun 2010 13:06:33 +0800

很多人的地方反应就是

引用内容

var pattern=/\d+(\.\d{2})?/gi;
var s=13.21;
alert(pattern.test(s))

或者

引用内容

var pattern=/\d+(\.\d{2})?/;
var s=13.21;
alert(pattern.test(s))

以上显示结果均正确，但是如果匹配13.121也一样返回true，那么怎么回事呢？

引用内容

var pattern=/^\d+(\.\d{2})?$/;
var s=13.213;
alert(pattern.test(s))

尝试修改成上面，一切正常，看出原因了么？
