C# and .NET interview questions: - What is reflection?

 Posted by ArticlesMaint on 9/20/2011 | Category: .NET Framework Interview questions | Views: 18712

Reflection helps us to browse methods, properties and function of a given class or assembly on run time. You can also invoke the methods and functions using reflection. Below is a simple sample code where we are browsing in run time through methods and function of “MyClass”.

MyClass objMyClass = new MyClass();

// Get the class type
Type parameterType = objMyClass.GetType();
string name = parameterType.Name;
// Browse through members
foreach (MemberInfo objMemberInfo in parameterType.GetMembers())

// Browse through properties.
foreach (PropertyInfo objPropertyInfo in parameterType.GetProperties())


If you want to invoke method and function you need to use the invoke member function as shown in the below code.

parameterType.InvokeMember("Display",BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.InvokeMethod | BindingFlags.Instance,null, objMyClass, null);

Microsoft's .NET stores type information as Metadata. Reflection is a mechanism to access this Metadata information and enable us to access it with our .NET Code.
