Question

I am converting a VB6 project to C# .Net but I have problems using Scripting.Dictionary. The error message is ” Scripting.Dictionary.this[ref object]’ is not supported by the language “. I want to get the item for a specific key.

key=astr[n];
Scripting.Dictionary m_dicValueOf;
strXPath = m_dicValueOf[astr[n]];

Answer 1

You can’t use ref or out parameters in an indexer in C#, so you can’t use an indexer that has a ref or out parameter.

(The reasoning behind the limitation in the language is of course that it makes no sense what so ever to change the key that you send to an indexer.)

Use the Dictionary<K,V> class from the framework instead. Example:

Dictionary<string, string> m_dicValueOf;

strXPath = m_dicValueOf[key];
