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();

NuGet
