Type Initializers in C# 3.0

This is really cool. C# version 3.0 has a new syntax for instantiating an object as well as setting a bunch of initial properties and values on it. This works for regular types as well as lists and dictionaries.

Look at this sample code below.


//
// Regular object initialization
//

// C# 2.0 and earlier

SaveFileDialog dialog = new SaveFileDialog();
dialog.CheckFileExists = false;
dialog.CheckPathExists = true;
dialog.OverwritePrompt = false;

// C# 3.0. Not a huge savings on lines, but less language clutter over all

var dialog = new SaveFileDialog
{
CheckFileExists = false,
CheckPathExists = true,
OverwritePrompt = false
};

// --------------------------------

//
// List initialization
//

// C# 2.0 style

List<string> stringList = new List<string>();
stringList.Add("FOO");
stringList.Add("BAR");
stringList.Add("BAZ");
stringList.Add("BANG");

// C# 3.0 style
var stringList = new List<string>{ "FOO", "BAR", "BAZ", "BANG" };


// --------------------------------

//
// Dictionary initialization
//

// C# 2.0 style

Dictionary<int, string> employeeNameMap = new Dictionary()<int, string>();;
employeeNameMap .Add(1, "Sally");
employeeNameMap .Add(2, "Tim");
employeeNameMap .Add(3, "Joe");
employeeNameMap .Add(4, "Jane");

// C# 3.0 style

var employeeNameMap = new Dictionary<int, string>
{
{1, "Sally"}, {2, "Tim"}, {3, "Joe"}, {4, "Jane"}
};

jQuery, Microsoft, and Nokia

jQuery team have two pieces news today: Microsoft and Nokia are taking the major step of adopting jQuery as part of their official application development platform. Not only will they be using it for their corporate development but they will be providing it as a core piece of their platform for developers to build with.

C# typeof - How it works?

typeof

The typeof operator is used to obtain the System.Type object for a type. A typeof expression takes the form:


where:

type The type for which the System.Type object is obtained.

Remarks

The typeof operator cannot be overloaded.

To obtain the run-time type of an expression, you can use the .NET Framework method GetType.

Example

// cs_operator_typeof.cs
// Using typeof operator
using System;
using System.Reflection;

public class MyClass
{
public int intI;
public void MyMeth()
{
}

public static void Main()
{
Type t = typeof(MyClass);

// alternatively, you could use
// MyClass t1 = new MyClass();
// Type t = t1.GetType();

MethodInfo[] x = t.GetMethods();
foreach (MethodInfo xtemp in x)
{
Console.WriteLine(xtemp.ToString());
}

Console.WriteLine();

MemberInfo[] x2 = t.GetMembers();
foreach (MemberInfo xtemp2 in x2)
{
Console.WriteLine(xtemp2.ToString());
}
}
}

Output

Int32 GetHashCode()
Boolean Equals(System.Object)
System.String ToString()
Void MyMeth()
Void Main()
System.Type GetType()

Int32 intI
Int32 GetHashCode()
Boolean Equals(System.Object)
System.String ToString()
Void MyMeth()
Void Main()
System.Type GetType()
Void .ctor()

How to get the path to my running EXE and DLL?

If you want to get the path of the running EXE of your project you might need to use this code.

EXE

The Application class has a static member ExecutablePath that has this information.

string appPath = Application.ExecutablePath;  

Howerver if you want to get the path of the executing assembly here is the code.

DLL

System.Reflection.Assembly.GetExecutingAssembly().Location 
Also, there are a number of ways to get the app.path in VB.NET. This particular method works for VB.NET (including windows forms applications and .dlls) and ASP.NET. Unlike App.Path in VB6, this includes the the "\" at the end of the value.

Declarations: none
Public Function App_Path() As String         
Return System.AppDomain.CurrentDomain.BaseDirectory()
End Function
