Calling indexer from within the same (generic) class

public class MyClass<T>
{
        public T this[int index]
        {
            get
            {
                ...
            }
            set
            {
                ...
            }
        }

        public void MyMethod<T>()
        {   
             int middleIndex = ...;              
             T value = this[middleIndex ];     
             ...             
        }           
}

The code won't compile because of the statement in MyMethod(). Is there another way of calling the indexer ?

Edit: Modified MyMethod()

Edit2: Compilation error

Error    6    Cannot implicitly convert开发者_运维知识库 type 'T [C:\MyClass.cs]' to 'T [C:\MyClass.cs]'

Thanks.

Works fine for me:

public class MyClass<T>
{
    public T this[int index]
    {
        get
        {
            return default(T);
        }
        set
        {
        }
    }

    public void MyMethod(int index)
    {                 
         T value = this[index];     
    }           
}

Admittedly I had to introduce the index parameter into MyMethod, but I'm assuming you were wanting to get the index from somewhere... if that's not what you meant, please clarify.

This works fine for me:

public class MyClass<T>
{
    List<T> _items = new List<T>();

    public T this[int index]
    {
        get
        {
            return _items[index];
        }
    }

    public void MyMethod()
    {
        T value = this[2];
    }
}

Calling the indexer is fine, but it doesn't know which index you want. If you make index a parameter of MyMethod it will work fine.

If you're trying to get the current index or something then you need to store a private variable, wire it up in your indexer and access that.

Your edited code compiles fine...

public class MyClass<T>
{
        public T this[int index]
        {
            get
            {
                ...
            }
            set
            {
                ...
            }
        }

        public void MyMethod()
        {   
             int middleIndex = ...;              
             T value = this[middleIndex ];     
             ...             
        }           
}

you're not passing in a value for the index into the method MyMethod - can you post a little more code? It looks like something is missing...

Your offending code is here:

public void MyMethod<T>()

Your class MyClass<T> already has a generic type parameter T, so the generic <T> on MyMethod is unnecessary
