CodeRush Classic shows the Cannot create an instance of interface code issue if an instance creation statement references an interface.
Create an instance of a class implementing the current interface.
Highlights the instance creation statements, which would cause the Cannot create an instance of the abstract class or interface compilation error.
interface IMyClass
{
void OutputText(string text);
}
public class TestClass
{
public TestClass()
{
IMyClass objVar = new │IMyClass();
}
}
Fix:
interface IMyClass
{
void OutputText(string text);
}
class MyClass: IMyClass
{
public override void OutputText(string text)
{
Console.Write(text);
}
}
public class TestClass
{
public TestClass()
{
IMyClass objVar = new MyClass();
}
}
