Generic Method - Cannot implicitly convert type 'string' to T

Question

May be a simple question..

I have an interface:

public interface ISanitizer
{
    T Sanitize(T data_);
}

And an implementi

Answer 1

In your code you are returning a string from a generic type which could be anything.

Change your code to this if you want a generic return type:

public interface ISanitizer
{
    T Sanitize(T data_);
}

public class BasicFilenameSanitizer : ISanitizer

If you simply want to always return a string you only need to change the method return type:

public interface ISanitizer
{
    string Sanitize(T data_);
}

public virtual string Sanitize(T filename_)
