Question

Suppose I have a class like

interface ISampleInterface
{
  void SampleMethod();
}

class ImplementationClass : ISampleInterface
{
// Explicit interface member implementation: 
void ISampleInterface.SampleMethod()
{
    // Method implementation.
}

static void Main()
{
    // Declare an interface instance.
    ISampleInterface obj = new ImplementationClass();

    // Call the member.
    obj.SampleMethod();
}
}

From the main method how could I determine that the ImplementationClass class implements ISampleInterface before writing the code like below

SampleInterface obj = new ImplementationClass();
obj.SampleMethod();

is there any way….please discuss. thanks.

You could use reflection:

bool result = typeof(ISampleInterface).IsAssignableFrom(typeof(ImplementationClass));
