Question

Here’s my method:

public void SomeQuery(string email = "", Guid userId = Guid.Empty)
{
   // do some query
}

userId is giving me an error as it must be a compile-time constant, which i understand. But even when i declare a const:

private const emptyGuid = Guid.Empty;

then change the method signature to:

public void SomeQuery(string email = "", Guid userId = emptyGuid)
{
   // do some query
}

still no love.

What am i missing?

Answer 1

Have you tried setting it to a new instance of Guid ala:

public void SomeQuery(string email = "", Guid userId = new Guid())
{
   // do some query
}

Should do the trick.
