Question

I have a method with this signature:

public void GenerateLog<TEntity>(TEntity entity) where TEntity : EntityObject

How can I loop through my ObjectContext and call this for each Entity in my ObjectContext?
I know that I can do this:

foreach (ObjectStateEntry entry in
                context.ObjectStateManager.GetObjectStateEntries(
                EntityState.Added | EntityState.Modified))
{
    string entityName = entry.Entity.GetType().Name;
}

But I don’t know how to go from a String representation of the name to GenerateLog<MYSTRING> instead of GenerateLog<TEntity>.

Answer 1

You need to make a generic method from your GenerateLog and then call that. I normally need to mess around a bit before I get something like this to work, but this should be close

MethodInfo generateLog = typeof(YourClass)
    .GetMethod("GenerateLog", BindingFlags.Public | BindingFlags.Instance );

MethodInfo genericGenerateLog = generateLog.MakeGenericMethod(entry.Entity.GetType());

genericGenerateLog.Invoke(this, new object[] { entry.Entity });

YourClass is simply the class the GenerateLog is in.
