Generic Constraints Situations

Here paste a form:

onstraint

Description

where T: struct

The type argument must be a value type. Any value type except Nullable can be specified.

where T : class

The type argument must be a reference type; this applies also to any class, interface, delegate, or array type.

where T : new()

The type argument must have a public parameterless constructor. When used together with other constraints, the new() constraint must be specified last.

where T : Baseclass

The type argument must be or derive from the specified base class.

where T : Iinterfacename

The type argument must be or implement the specified interface. Multiple interface constraints can be specified. The constraining interface can also be generic.

Let's take the constructor constraints as an example:

where T: new(), this means when we instantiate T, we limit the class constructor doesn't have parameter,

and where T: new(int,string), Then when we instantiate T, we can only write T t=new T(3, "string") like this.

WebRequest and WebResponse Examples

As there are lot's of contents to talk about in C# network programming, in this article I am going to talk only a bit on the WebRequest/WebResponse briefly.

In this article I am going to talk about something on WebRequest, WebResponse method. I will talk about the WebRequest Method property to be "GET", "POST", "HEAD" et al to Get or Post a uri or get the Header contents. For the "POST", I am going to write some examples on the context type to be "text/xml" or "application/x-www-form-urlencoded" types. I am also going to write some sample code to talking about create a Webrequest object to call a SiteMinder protected resources.

The simplest example use "GET" method to request a uri:
eg.

var request=WebRequest.Create("http://...");
We can set the request properties, such as:
request.Credentials=CredentialCache.DefaultCredentials;
sometimes need use network credentials:(request.Credentials=new NetworkCredential(UserName, Password))
Sometimes we need to specify the Authentication lvl, such as:
request.AuthenticationLevel=System.Net.Security.AuthenticationLevel.MutualAuthRequested;

For the AuthenticationLevel, it can be None, MutualAuthRequested, MutualAuthRequired. which means no authentication, need client side authentication, and both server and client sides authentication mechanism.

Dynamically Create Image and write Text Over it

using System.Drawing;

using System.Drawing.Imaging;

using System.Globalization;

///

/// The program.

///

internal class Program

{

private static void Main(string[] args)

{

var chartWidth = 500;

var chartHeight = 200;

Bitmap bitmap = new Bitmap(chartWidth, chartHeight);

Graphics graphics = Graphics.FromImage(bitmap);

using (Font font = new Font("Arial", 20, FontStyle.Bold))

{

var text = string.Format(CultureInfo.InvariantCulture, "Chart Unavailable");

SizeF size = graphics.MeasureString(text, font);

graphics.DrawString(

text,

font,

Brushes.Black,

(((float)chartWidth / 2) - (size.Width / 2)),

(((float)chartHeight / 2) - (size.Height / 2)));

graphics.Dispose();

}

bitmap.Save("test.png", ImageFormat.Png);

//bitmap.Save(memoryStream, ...)

}

}

}

Create Section in the Configure file and Read Parameters from it

Create section in config file is pretty much like:

< ? xml version="1.0" encoding="utf-8" ?> 
<configuration>
  <configSections>
    <section name="InstrumentationSettings" type="System.Configuration.NameValueFileSectionHandler" />
  < /configSections>
  < ! -- < InstrumentationSettings file="instrumentation.xml"  /> --> 
  <InstrumentationSettings>
    <add key="MachineName" value="EMC01" />
    <add key="UserID" value="03" />
    <add key="CPU" value="2.8G" />
    <add key="Memory" value="2G" />
  < /InstrumentationSettings> configuration>

To Read the information, the code is pretty much like:

using System; using System.Collections.Specialized; 
using System.Configuration;        
internal class Program     
{         
       private static void Main(string[] args)         
      {        
          var instSettings = ConfigurationManager.GetSection("InstrumentationSettings") as NameValueCollection;            
            if (null != instSettings)
            {               
               Console.WriteLine(instSettings["MachineName"]);
            }
        }
}
Similar code like:
                    
 Dictionary< string,string >  instSettingsDict = new Dictionary< string, string >();
            if (null != instSettings)
            {
                for (int i = 0; i < instSettings.Count; i++)
                {
                 instSettingsDict.Add(instSettings.Keys[i], instSettings[instSettings.Keys[i]]);
                }
            }
