Code Example
Describing the target
To access or invoke a private method that is defined on a type
or an object
client code needs to specify the target correctly.
Targets' members can be either static or instance.
Notice that constructors
must be accessed through a static target since no instance target is available yet:
class MyClass {
private string name;
private MyClass() { this.name = "Name is not set"; }
private MyClass(string name) { this.name = name; }
}
MyClass targetObject = ...;
var staticTarget = Use.Target<MyClass>();
// staticTarget can now be used to call constructor or
// call or access static members
var instanceTarget = Use.Target(targetObject)
// instanceTarget can now be used to call or access targetObject's members
Creating an instance of an object
// Creates object by calling its default constructor
MyClass newInstance = Use.Target<MyClass>().ToCreateInstance();
// Creates object by calling its best matching parameterized constructor
MyClass newInstance = Use.Target<MyClass>().ToCreateInstance("Alice");
Working with instance members
class MyClass {
private string name;
private string Name { get { return name; } set { name = value } }
private void SetName(string newName) { name = newName; }
private string GetName() { return name; }
}
MyClass target = new MyClass();
// Field/Property access code looks similar
Use.Target(target).Set("name").Value("Bob")
Use.Target(target).Set("Name").Value("Chris")
string nameFromField = Use.Target(target).ToGet<string>("name");
string nameFromProperty = Use.Target(target).ToGet<string>("Name");
// Method access
Use.Target(target).ToCall("SetName", "David");
string nameFromMethod = Use.Target(target).ToCall<string>("GetName");
Working with static members
static class MyClass {
private static string name;
private static string Name { get { return name; } set { name = value } }
private static void SetName(string newName) { name = newName; }
private static string GetName() { return name; }
}
Use.Target<MyClass>().Set("name").Value("Bob")
string nameFromStaticField = Use.Target<MyClass>().ToGet<string>("name");
Use.Target<MyClass>().Set("Name").Value("Chris")
string nameFromStaticProperty = Use.Target<MyClass>().ToGet<string>("Name");
Use.Target<MyClass>().ToCall("SetName", "David");
string nameFromStaticMethod = Use.Target<MyClass>().ToCall<string>("GetName");
Attribute discovery
Attribute retrieval can be string-based (full type name argument required).
IEnumerable<Attribute> obsoleteClassAttribute =
typeof(TargetClass)
.GetAttributes("System.Obsolete")
.SingleOrDefault();
IEnumerable<Attribute> obsoleteMethodAttribute =
typeof(TargetClass)
.GetMethod("TargetMethod")
.GetAttributes("System.Obsolete")
.SingleOrDefault();
Alternatively, the generic method can be used if specific attribute type is known at compile time.
IEnumerable<Obsolete> obsoleteClassAttribute =
typeof(TargetClass)
.GetAttributes<Obsolete>()
.SingleOrDefault();
IEnumerable<Obsolete> obsoleteMethodAttribute =
typeof(TargetClass)
.GetMethod("TargetMethod")
.GetAttributes<Obsolete>()
.SingleOrDefault();
Motivation
Syntax sugar is syntax sugar: it's not a necessary thing per se but it can improve code quality. Reflection should be your last resort tool when used in production code: types very often limit constructor and other members' accessibility level on purpose.
In your tests, however, it may be okay to have slightly sloppier code. For example, you may want to build a dummy/fake object and for some reason mocking tools like NSubstitute can't do it.

Reporting an Issue
Reporting an issue, proposing a feature, or asking a question are all great ways to improve software quality.
Here are a few important things that package contributors will expect to see in a new born GitHub issue:
- the relevant version of the package;
- the steps to reproduce;
- the expected result;
- the observed result;
- some code samples illustrating current inconveniences and/or proposed improvements.
