Intepreter dosn't recognise object- possible C# bug?

[GMMorris]

Hi,

I've encountered a really strange thing.

I have this code:

m_sFilename = Dict.ChildKeys["Filename"].ToString();

 

which basicaly places the value of the string object stored in the Dict.ChildKeys hashtable into the string variable m_sFilename.

 

The problem is, the expression Dict.ChildKeys["Filename"] returns null, and so m_sFilename now contains an empty string.

 

The thing is, that I then tried explicitly telling the interpreter that the "ChildKeys" property returns a hashtable (see code below) and now it returns the correct value of the object stored in the hashtable.

m_sFilename = ((System.Collections.Hashtable)(Dict.ChildKeys))["Filename"].ToString();

 

Any ideas why this would happen? I can leave my Sourcecode like in the lower code example, but that isn't as readable and is ugly.

 

Any ideas?
