.NET Object Inspector
[](https://www.nuget.org/packages/Wanhjor.ObjectInspector/)
An efficient .NET object inspector/accesor to avoid reflection usage.
PropertyFetcher, FieldFetcher, MethodCaller and DuckTyping for .NET by Expression Trees or Emitting IL at runtime.
## Target Frameworks
`netstandard2.0`, `netstandard2.1`, `netcoreapp2.0`, `netcoreapp2.1`, `net461`, `net462`, `net471`, `net472`, `net48` and `net45`.
### Dependencies for *netstandard2.0*:
- `System.Reflection.Emit (>= 4.7.0)`
- `System.Reflection.Emit.Lightweight (>= 4.7.0)`
## Usage
Given the following class with private members, the object inspector can help you to Get, Set or Invoke members of the object instance:
```cs
namespace OtherAssembly
{
public class SomeClass
{
private string _privateField = "This field it's so private...";
private string PrivateProperty { get; set; } = "You can't read this";
private void PrivateConsoleWrite(string line) => Console.WriteLine(line);
}
public static class ObjectFactory
{
public static object New() => new SomeClass();
}
}
```
> **Note** You can inspect, public or non public types with public or non public members, also it's compatible with anonymous objects.
>As you can see in the following code: [](https://dotnetfiddle.net/cBAmGG)
### By using a Duck Typing mechanism
Duck Typing can be done by using an Interface, Abstract class or a class with virtual members. The library will create a proxy type inheriting/implementing the base type.
```cs
namespace MyAssembly
{
public interface IDuckSomeClass
{
[Duck(Name="_privateField", Kind = DuckKind.Field, Flags = DuckAttribute.AllFlags)]
string PrivateField { get; set; }
[Duck(Flags = DuckAttribute.AllFlags)]
string PrivateProperty { get; set; }
[Duck(Flags = DuckAttribute.AllFlags)]
void PrivateConsoleWrite(string line);
}
public class Program
{
public static void Main()
{
var obj = OtherAssembly.ObjectFactory.New();
HandleObject(obj);
}
public static void HandleObject(object obj)
{
// We can treat the object as it were implementing the IDuckSomeClass interface
var duck = obj.DuckAs();
Console.WriteLine(duck.PrivateField);
Console.WriteLine(duck.PrivateProperty);
Console.WriteLine();
duck.PrivateField += " or not!";
duck.PrivateProperty += ". I think I can!";
Console.WriteLine(duck.PrivateField);
Console.WriteLine(duck.PrivateProperty);
Console.WriteLine();
duck.PrivateConsoleWrite("Sooo private...");
}
}
}
```

### By using a DynamicFetcher
```cs
namespace MyAssembly
{
public class Program
{
public static void Main()
{
var obj = OtherAssembly.ObjectFactory.New();
HandleObject(obj);
}
private static readonly DynamicFetcher _privateFieldFetcher = new DynamicFetcher("_privateField", DuckAttribute.AllFlags);
private static readonly DynamicFetcher _privatePropertyFetcher = new DynamicFetcher("PrivateProperty", DuckAttribute.AllFlags);
private static readonly DynamicFetcher _privateConsoleWriteFetcher = new DynamicFetcher("PrivateConsoleWrite", DuckAttribute.AllFlags);
public static void HandleObject(object obj)
{
// We can handle the object using a dynamic fetcher
Console.WriteLine((string)_privateFieldFetcher.Fetch(obj));
Console.WriteLine((string)_privatePropertyFetcher.Fetch(obj));
Console.WriteLine();
_privateFieldFetcher.Shove(obj, "This field it's so private... or not!");
_privatePropertyFetcher.Shove(obj, "You can't read this. I think I can!");
Console.WriteLine((string)_privateFieldFetcher.Fetch(obj));
Console.WriteLine((string)_privatePropertyFetcher.Fetch(obj));
Console.WriteLine();
_privateConsoleWriteFetcher.Invoke(obj, "Sooo private...");
}
}
}
```

### By using an Object Inspector
```cs
namespace MyAssembly
{
public class Program
{
public static void Main()
{
var obj = OtherAssembly.ObjectFactory.New();
HandleObject(obj);
}
public static void HandleObject(object obj)
{
var inspector = new ObjectInspector(new InspectName("_privateField", DuckAttribute.AllFlags),
new InspectName("PrivateProperty", DuckAttribute.AllFlags),
new InspectName("PrivateConsoleWrite", DuckAttribute.AllFlags));
var viewer = inspector.With(obj);
Console.WriteLine((string)viewer["_privateField"]);
Console.WriteLine((string)viewer["PrivateProperty"]);
Console.WriteLine();
viewer["_privateField"] = "This field it's so private... or not!";
viewer["PrivateProperty"] = "You can't read this. I think I can!";
Console.WriteLine((string)viewer["_privateField"]);
Console.WriteLine((string)viewer["PrivateProperty"]);
Console.WriteLine();
viewer.Invoke("PrivateConsoleWrite", "Sooo private...");
}
}
}
```

### By using an Inspector Tuple
```cs
namespace MyAssembly
{
public class Program
{
public static void Main()
{
var obj = OtherAssembly.ObjectFactory.New();
HandleObject(obj);
}
public static void HandleObject(object obj)
{
var inspTuple = new InspectorTuple(new InspectName("_privateField", DuckAttribute.AllFlags),
new InspectName("PrivateProperty", DuckAttribute.AllFlags),
new InspectName("PrivateConsoleWrite", DuckAttribute.AllFlags));
inspTuple.SetInstance(obj);
Console.WriteLine(inspTuple.Item1);
Console.WriteLine(inspTuple.Item2);
Console.WriteLine();
inspTuple.Item1 = "This field it's so private... or not!";
inspTuple.Item2 = "You can't read this. I think I can!";
Console.WriteLine(inspTuple.Item1);
Console.WriteLine(inspTuple.Item2);
Console.WriteLine();
inspTuple.InvokeItem3("Sooo private...");
}
}
}
```
