Inconsistent accessibility error with the following c# code. Why?

Question

Whats wrong with the following c# code? Compiler reports this error:

Inconsistent accessibility: parameter type 'ClassLibrary1.Interface1' is less accessible than method 'ClassLibrary1.Class1.Class1(ClassLibrary1.Interface1)'

with the following code:

interface Interface1<T>
{
    bool IsDataValid();
    /* Other interfaces */
}

public class Class1<T>
{
    public Interface1<T> interface1;

    public Class1(Interface1<T> interface1)
    {
        this.interface1 = interface1;
    }

}

I've since designed my code differently using inheritence to but if anyone could tell me what the above is wrong I'd greatly appreciate it.

Answer 1

your "Interface1" isn't public..

public interface Interface1<T>
{
    bool IsDataValid();
    /* Other interfaces */
}
