C# .Net Reflection Kullanım Örneği

Örneğin test namespace'i ile oluşturulan projenin dll'ini ele alalım.

[C#]

namespace Test 

{ 

public class Calculator 

 {

public Calculator() { ... } 

private double _number; 

public double Number { get { ... } set { ... } } 

public void Clear() { ... }         private void DoClear() { ... } 

public double Add(double number) { ... } 

public static double Pi { ... } 

public static double GetPi() { ... }

 } 

}  

[C#]

// dynamically load assembly from file Test.dll 

Assembly testAssembly = Assembly.LoadFile(@"c:\Test.dll");

// get type of class Calculator from just loaded assembly 

Type calcType = testAssembly.GetType("Test.Calculator");

// create instance of class Calculator                                                                                    

 object calcInstance = Activator.CreateInstance(calcType); 

// get info about property: public double Number                                                                  

PropertyInfo numberPropertyInfo = calcType.GetProperty("Number"); 

// get value of property: public double Number                                                                       

double value = (double)numberPropertyInfo.GetValue(calcInstance, null); 

// set value of property: public double Number                                                                       numberPropertyInfo.SetValue(calcInstance, 10.0, null); 

// get info about static property: public static double Pi       

PropertyInfo piPropertyInfo = calcType.GetProperty("Pi"); 

// get value of static property: public static double Pi                                                           

double piValue = (double)piPropertyInfo.GetValue(null, null); 

// invoke public instance method: public void Clear()                                                           

calcType.InvokeMember("Clear",     BindingFlags.InvokeMethod | BindingFlags.Instance | BindingFlags.Public,     null, calcInstance, null); 

// invoke private instance method: private void DoClear()

calcType.InvokeMember("DoClear",     BindingFlags.InvokeMethod | BindingFlags.Instance | BindingFlags.NonPublic,     null, calcInstance, null); 

// invoke public instance method: public double Add(double number)                                 

double value = (double)calcType.InvokeMember("Add",     BindingFlags.InvokeMethod | BindingFlags.Instance | BindingFlags.Public,     null, calcInstance, new object[] { 20.0 }); 

// invoke public static method: public static double GetPi()                                                 

double piValue = (double)calcType.InvokeMember("GetPi",     BindingFlags.InvokeMethod | BindingFlags.Static | BindingFlags.Public,     null, null, null); 

// get value of private field: private double _number                                                            

double value = (double)calcType.InvokeMember("_number",     BindingFlags.GetField | BindingFlags.Instance | BindingFlags.NonPublic,     null, calcInstance, null);
