C# & VB.NET Conversion Pocket Reference

End Sub

End Class

Notice from this example that you must add a call to invoke

the base class’s constructor. To do this you must use the

MyBase keyword. The keyword MyBase can be used to invoke

any method in the base class. Unlike C#, in which you use

the

base keyword without specifying the name of a function,

in VB you must use

MyBase in combination with the New key-

word. The VB compiler forces you to write the line

MyBase.

New( )

before any other code in the constructor.

Initializers

Field initializers are class fields that are initialized in place, as

in the following C# example:

class Account

{

int Balance = 100;

public void MakeDeposit( )

{

}

}

The line:

int Balance = 100

is a field initializer. This code does not have an explicit con-

structor function. However, if you do not provide one, the

C# compiler adds a default constructor. It also adds code to

this constructor to invoke the field initializers. In other

words, when the code is compiled, the result should resem-

ble the following:

class Account

{

int Balance;

public Account( )

{

Balance = 100; //field initializers

base( ); //call the base constructor

If your code contains multiple constructors, the compiler

adds the code ...
