FastAccessors 1.0.0.1

FastAccessors

Fast Accessors Library for .NET.
Allows you to access any fields of your .NET classes as fast as you want.

Usage

Let the Foo class is defined as follows:

class Foo {
    string private_Name; 
    int private_Field; 
    static int static_Field; 
}

If you want to get access to it's fields you can use the "by-name" accessors:

using FastAccessors;
//...
Foo foo = new Foo()
// access to the specific private field by field-name
string _name = foo.@ƒ("private_Name") as string;

It's quite fast. But, if you want to be faster, you can use "field-keys":

using FastAccessors;
// Field-Keys initialization
int fldKey_private_Field = "private_Field".@ƒRegister(typeof(Foo));
int fldKey_static_Field = "static_Field".@ƒsRegister(typeof(Foo));
//...
Foo foo = new Foo()
// access to the specific private field by field-key
int _field = (int)foo.@ƒ(fldKey_private_Field);
// access to the specific static field by field-key
int _s_field = (int)typeof(Foo).@ƒs(fldKey_Static_Field);

To be fastest use the "default-fields":

using FastAccessors;
// default-fields initialization
"private_Name".@ƒRegister(typeof(Foo), true); // default instance-field
"static_Field".@ƒsRegister(typeof(Foo), true); // default static field
//...
Foo foo = new Foo()
// access to the default-fields
string _name = foo.@ƒDefault() as string;
int _s_Field = (int)foo.@ƒsDefault();
