Object Members
Besides methods and fields, C# has other class members, such as properties, indexers, and events. A property is sometimes called a smart field; it has a get accessor to customize value retrieval and a set accessor to customize setting the value. Here's an example of a property:
private short foo;
public short Foo
{
get
{
return foo;
}
set
{
foo = value;
}
}
The previous code could be used like this (assuming that the property is a member of MyClass):
MyClass.Foo = 25; Short myField = MyClass.Foo;
And here's an example of an indexer, which enables a class to provide array-like semantics.
private ArrayList junk = new ArrayList();
public this[int index]
{
get
{
return junk[index];
}
set
{
junk[index] = value;
}
}
The previous code could be used like this (assuming that the property is a member of MyClass):
MyClass[5] = "somestring"; string myString = MyClass[2];
Indexers and properties don't look like any of Java's syntactical constructs.
It would be difficult for C# to mimic Java with overloaded operators such as these:
public static MyClass operator+(MyClass bar1, MyClass bar2)
{
// some implementation
}
That's especially true because Java doesn't have overloaded operators.
