Pass concrete object type as parameter for generic method

Question

I have an API using generic method as follow

public static class DataProvider
{
    public static Boolean DeleteDataObject(Guid uid, IDbConnection d         


        

Answer 1

I suspect you want something like this:

public static Boolean PurgeDataObject(this IDataObject dataObject, Guid uid)
{
    return PurgeDataObjectImpl((dynamic) dataObject, uid);
}

private static Boolean PurgeDataObjectImpl(T dataObject, Guid uid)
    where T : IDataObject
{
    return DataProvider.DeleteDataObject(uid, DataProvider.GetConnection());
}

That uses dataObject dynamically, getting the "execution-time compiler" to perform type inference to work out T.

You could just use reflection to do this yourself, using MethodInfo.MakeGenericMethod - but this way is certainly less code.
