C＃GetMethod抛出异常：对象引用未设置为对象的实例

Question

I had a generic method that I'd like to invoke, but it throws the exception below:

Object reference not set to an instance of an object.

It's in fact the GetMethod(...) who equals to null. But I can't find where I did wrong cause I had a very similar function in another class. This is the code simple:

Class DatabaseSyncronizor
{
    ...
    internal void SyncronizeAll()
    {
           for(int i=0;i<MyList.Count();i++)
           {
                Type type=Type.GetType(MyModelClass);
                typeof(DatabaseSyncronizor).GetMethod("Synchronize",BindingFlags.NonPublic|BindingFlags.Instance).MakeGenericMethod(type).Invoke(this, null);

            }
      }


    private void Syncronize<T>() where T :class,IDate
    {
         IGenericService<T> service = new GenericService<T>(new UnitOfWorkFactory(_connectionString));
         ...
    }
}

Thank you for you help!

Answer 1

Your method is called Syncronize not Synchronize.

Try this

typeof(DatabaseSyncronizor).GetMethod("Syncronize",BindingFlags.NonPublic|BindingFlags.Instance)
                           .MakeGenericMethod(type).Invoke(this, null);
