Custom object and ToString()

It is known that in the C # any object can be shown in the form of string by the method ToString () but what to do if you need to make such an operation with custom object?
That is one solution :

        public int Id
        {
            get { return id; }
            set { id = value; }
        }
        private string name;
        public string Name
        {
            get { return name; }
            set { name = value; }
        }
        private DateTime birthday ;
        public DateTime Birthday 
        {
            get { return birthday ; }
            set { birthday  = value; }
        }

      
       //Constructor
       public Customer()
       {
        this.id = 5;
        this.name = "John Smith";
        this.birthday = new  DateTime(1945, 10, 12);

        Console.WriteLine(this.ToString());
       }



To continue press "read more"....

public override string ToString()
 {
   StringBuilder builder = new StringBuilder();

   Type type = this.GetType();
   PropertyInfo[] propertiesInfo =
                      type.GetProperties();
   foreach (PropertyInfo property in propertiesInfo)
        {
           builder.AppendFormat("{0} = {1} \n",
                     property.Name,
                    property.GetValue(this, null));
         }

          return builder.ToString();
 }

Convert any possible type to T in .Net 2005

private T TryConvert <T>(object o, T defaultValue, bool isThrowException)
{
    T convertedValue = defaultValue;
    try
    {
     if (o != null)
      {
       convertedValue = (T)Convert.ChangeType(o, typeof(T));
      }
     else
      throw;
    }
    catch
    {
     if (isThrowException)
      {
       throw;
      }
    }
   return convertedValue;
}

How to use:


Let us suppose you have HttpRequest with some parameters:
ID , Name and Flag
Example 1. Simple using

private void Examle()
 {
   int id      =
     TryConvert<int>(Request["id"], -1,
 true);
   string name =
     TryConvert<string>(Request["name"], string.Empty,
 true);
   bool flag   =
     TryConvert<bool>(Request["Flag"], default(bool),
 true);
 }

Example 2. Using in enum

 public enum Week
        {
            Monday,
            Tuesday,
            Wednesday,
            Thursday,
            Friday,
            Saturday,
            Sunday
        }

 private void Examle2(Week w)
{
   Week day = TryConvert<Week>(w, Week.Sunday, true);
}

NMock

NMock is a dynamic mock object library for .NET. Mock objects make it easier to test single components—often single classes—without relying on real implementations of all of the other components. This means we can test just one class, rather than a whole tree of objects, and can pinpoint bugs much more clearly.

HttpHandler in WebSite VS 2005

This example intended to case, when classes located in App_Code.

HttpHandler:

public class TestHandler : IHttpHandler
{
        public TestHandler() {}

        public  void ToDo()
        {
         //....
        }

    public bool IsReusable
        {
            get { return true; }
        }
        void IHttpHandler.ProcessRequest(

               HttpContext context)      
        {
           ToDo();
        }

Add an uninstall and him shortcut to .NET deployment project in VS2005

1. Create simple project UninstallApp.
2. Add in Main()

{
string[] arguments = Environment.GetCommandLineArgs();

foreach(string argument in arguments)
{
string[] parameters = argument.Split('=');
if (parameters[0].ToLower() == "/u")
{
string productCode = parameters[1];
string path = Environment.GetFolderPath(Environment.SpecialFolder.System);
Process proc = new Process();
proc.StartInfo.FileName = string.Concat(path,"\\msiexec.exe");
proc.StartInfo.Arguments = string.Concat(" /i ", productCode);
proc.Start();
}

}


3. Create new setup project
4. Add UninstallApp.exe to "Application Folder" in 'File System' part
5. In "User's Program menu" create shortcut to UninstallApp.exe and in properties of this shortcut in parameter 'arguments' insert value "/u=[ProductCode]".
6.Rebuild deployment project.

Good luck ;)

Event Log Explorer

The small freeware utility for monitoring and the subsequent analysis of the events which have been written down in system log of operational systems of family Windows NT (NT/2000/XP/2003). It is called to expand functionality of built in component Event Viewer from OS and to add new opportunities its Interface it is extremely simple, divided for convenience into two windows. In left the tree of magazines (by default in Windows XP them three is displayed: for appendices, safety and system), and in right - tables with brief data on events, somehow: date, time, a code of event, a source and other. The arrangement of windows in the right half is limited by nothing, it is possible to look through simultaneously set of logs without restrictions. Probably to organize the selected lists for the separate computers connected through removed access on a network. Functions archiving old logs are supported, there is an advanced system of a filtration by various criteria and text search, and also the expanded functions of a press and export to various formats (HTML, TXT or in Excel). The program is very useful, as by means of it it will be much easier (unlike a standard browser of events Windows) to trace failure of this or that appendix, systems or the driver.
